A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 7, 11-12, 15, 17-18 are rejected under 35 U.S.C. 103 as being unpatentable over Figulla et al. (Pub. No.: US 2014/0088696) in view of Chang et al. (Pub. No.: US 2017/0156859).
For claim 7, Figulla discloses an implantable heart valve system, comprising:
an implantable heart-valve apparatus (e.g., fig. 1) comprising
a tubular braided (e.g., para. 19) frame, having an inflow end (end with atrial side anchoring elements 6a-d) and an outflow end (end with ventricular-side anchoring members 4a-d);
a flange extending from the inflow end of the tubular braided frame (fig. 1); and
a plurality of engagement attachments 4a-d extending out from the outflow end, the engagement attachments comprising a leaflet anchor 4b. 4c (e.g., fig. 2) and two shape set stabilization anchors 4a, 4d (e.g., fig. 2), wherein the leaflet anchor is disposed between the two shape set stabilization anchors (e.g., fig. 1), wherein the tubular braided frame and the plurality of engagement attachments define a singular component (e.g., fig. 1);
a delivery component comprising one or more suture lines connected on a first end to the implantable heart-valve apparatus;
wherein the one or more suture lines connects on a second end to the delivery component (not disclosed).
As provided in italicized text above, Figulla lacks a delivery component with one ore more suture lines connected on a first end to the implantable heart valve apparatus and on a second end to the delivery component. Figulla does include rings 4’ and 6’ on the end of each anchoring element, however, Figulla does not suggest that these rings are used for a suture line interconnected with a delivery component. Chang et al. (hereinafter, Change) teaches interconnecting a delivery catheter with a heart valve implant using suture loops 172 interconnected with a delivery catheter 104 for the purpose of providing control over the expansion and compression of the prosthetic valve (e.g., para. 79). It would have been obvious to one of ordinary skill in the art at the time the invention was filed to have provided the Figulla implant with suture loops and a delivery catheter as taught by Chang for the purpose of providing reversible control over the deployment of the prosthetic valve, ensuring more accurate placement. This modification would have occurred using known methods and would have yielded predictable results.
For claim 11, Figulla discloses the system of claim 7, wherein the two shape set stabilization anchors are between 120 to 180 degrees apart (e.g., fig. 1, 2).
For claim 12, Figulla discloses a method for percutaneous deployment and placement (e.g., para. 5) of an implantable heart-valve apparatus, comprising:
an implantable heart-valve apparatus 2 and a delivery component (e.g., para. 5);
wherein the implantable heart-valve apparatus comprises a tubular braided frame (e.g., para. 19), an inflow end (end with atrial side anchoring elements 6a-d) and an outflow end (end with ventricular-side anchoring members 4a-d); wherein the tubular braided frame extends out from the inflow end to form at least one flange (fig. 1); and wherein the tubular braided frame extends out from the outflow end to form engagement attachments 4a-d comprising a leaflet anchor4b, 4c and two shape set stabilization anchors 4a, 4d (e.g., fig. 2), wherein the leaflet anchor is disposed between the two shape set stabilization anchors (e.g., fig. 1), wherein the tubular braided frame and at least one of the two shape set stabilization anchors are integrally formed as a single component (e.g., para. 17);
wherein the delivery component comprises one or more suture lines and wherein the one or more suture lines goes through the heart-valve apparatus and connects to the delivery component (not disclosed);
percutaneously placing the implantable heart-valve apparatus into one of a vein or an artery (e.g., para. 26);
delivering the implantable heart-valve apparatus to a native heart valve; placing the implantable heart-valve apparatus in the position of the native heart valve (e.g., para. 26); and
expanding the engagement attachments by releasing one or more of the suture lines (not disclosed),
wherein when deployed in a native valve comprising a native annulus and one or more native leaflets, the leaflet anchor engages behind the one or more native leaflets and the two shape set stabilization anchors extend towards the native annulus (e.g., fig. 2).
As provided in italicized text above, Figulla lacks a delivery component with one ore more suture lines connected on a first end to the implantable heart valve apparatus and on a second end to the delivery component, and the method step of expanding the engagement attachments by releasing one or more of the suture lines. Figulla does include rings 4’ and 6’ on the end of each anchoring element, however, Figulla does not suggest that these rings are used for a suture line interconnected with a delivery component. Chang et al. (hereinafter, Change) teaches interconnecting a delivery catheter with a heart valve implant using suture loops 172 interconnected with a delivery catheter 104 for the purpose of providing control over the expansion and compression of the prosthetic valve (e.g., para. 79). These suture loops engage openings on the heart valve prosthesis and allow for expansion by releasing the suture lines (e.g., para. 79). It would have been obvious to one of ordinary skill in the art at the time the invention was filed to have provided the Figulla implant with suture loops and a delivery catheter as taught by Chang for the purpose of providing reversible control over the deployment of the prosthetic valve, ensuring more accurate placement. It would have been obvious to one of ordinary skill in the art to have provided the suture line son the engagement attachments as an obvious location to control the expansion and contraction of the engagement attachments during implant delivery. This modification would have occurred using known methods and would have yielded predictable results.
For claim 15, Figulla discloses the method of claim 12, wherein the vein is a femoral vein and wherein delivering the implantable heart-valve apparatus to a native heart valve comprises delivering the implantable heart-valve apparatus through the vena cava and through a puncture in the atrial septum (e.g., para. 27). Use of the femoral vein to access the trans-septal implant procedure is considered an obvious expedient.
For claim 17, Figulla discloses the method of claim 12, wherein the two shape set stabilization anchors are between 120 to 180 degrees apart (fig. 1).
For claim 18, Figulla discloses the method of claim 12, wherein the tubular braided frame is a receiver for a replacement heart valve (abstract).
Claims 2-4 are rejected under 35 U.S.C. 103 as being unpatentable over Figulla et al. (Pub. No.: US 2014/0088696) in view of Haug et al. (Pub. No.: US 2005/0137693).
For claims 2-4, Figulla does not specify the engagement attachments are grafted on the tubular braided frame, are welded onto the frame, or comprise a tubular braided frame first wire and an engagement attachment second wire attached to the first wire. Figulla does teach the engagement attachments are integral to the tubular braided frame (para. 17), and welding is a known means of providing an integral attachment. Additionally, Haug et al. (hereinafter, Haug) teaches welded ends on a braided prosthesis as a suitable attachment (e.g., fig. 7A-J). Haug further teaches braiding two wires, where the tubular body is a first wire and an engagement attachment is a second wire (e.g., fig. 10C). This is considered a grafted engagement attachment. It would have been obvious to one of ordinary skill in the art at the time the invention was filed to have provided Figulla with multiple wire braids, grafted engagement attachments, and welds as taught by Haug as an obvious expedient to provide the integral braided structure of Figulla. This modification would have occurred using known methods and would have yielded predictable results.
Claims 8-10, 13-14, 16 are rejected under 35 U.S.C. 103 as being unpatentable over Figulla et al. (Pub. No.: US 2014/0088696) in view of Chang et al. (Pub. No.: US 2017/0156859), further in view of Haug et al. (Pub. No.: US 2005/0137693).
For claims 8-10, 13-14, 16, Figulla and Chen do not specify the engagement attachments are grafted on the tubular braided frame, are welded onto the frame, or comprise a tubular braided frame first wire and an engagement attachment second wire attached to the first wire. Figulla does teach the engagement attachments are integral to the tubular braided frame (para. 17), and welding is a known means of providing an integral attachment. Additionally, Haug teaches welded ends on a braided prosthesis as a suitable attachment (e.g., fig. 7A-J). Haug further teaches braiding two wires, where the tubular body is a first wire and an engagement attachment is a second wire (e.g., fig. 10C). This is considered a grafted engagement attachment. It would have been obvious to one of ordinary skill in the art at the time the invention was filed to have provided Figulla and Chen with multiple wire braids, grafted engagement attachments, and welds as taught by Haug as an obvious expedient to provide the integral braided structure of Figulla. This modification would have occurred using known methods and would have yielded predictable results.
