Office Action

§102
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1-20 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by FOJTIK et al. (2020/0230359-of record). Regarding claims 1-3, 5-11, 13-14, and 20-25, FOJTIK et al. discloses a method of manufacturing an intravascular catheter, comprising: providing a hypotube structure having a tubular body with a proximal end, a distal end, a pattern of apertures and solid elements disposed on the distal end of the tubular body, and a hypotube lumen extending between the proximal end and the distal end of the tubular body (Fig.9); providing a polymer tube having a tube lumen (46); providing an outer polymer jacket (160); affixing the outer polymer jacket to an exterior surface of the hypotube structure [0066]; disposing the polymer tube within the hypotube lumen; radially expanding the polymer tube within the hypotube lumen; and intermittently attaching the polymer tube to at least some of the solid elements of the hypotube structure and/or the outer polymer jacket at at least one discrete adhesion region along a length of the distal end of the tubular body ([0057],[0074]; claims 17-19). Regarding claim 4, FOJTIK et al. discloses coating with a bond layer [0073]. Regarding claim 12, FOJTIK et al. discloses the tube thickness is 0.00025 inch to about 0.0005 inch [0057]. Regarding claims 15-19, FOJTIK et al. discloses coating a bond layer (tie layer) to the outer surface [0073]. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: a) McNiven et al. (10,661,052) discloses intravascular device delivery sheath. b) Goodin et al. (2004/0068240) discloses covered hypotube to distal port bond.
