Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify the adaptor lumen of Mansour so that the adaptor lumen has a constant-diameter segment extending from the tapered segment to the distal end of said adaptor body as taught by Enomoto for the purpose of allowing the fluid to pass through the lumen (Enomoto. ¶0129) . Re claim 5, Mansour fails to disclose further comprising a tubular element extending within the constant-diameter segment of the adaptor lumen. However, Enomoto discloses an adaptor (3’, Fig. 6-10. 32, 34, 35, ¶0128) and wherein the adaptor has a lumen (341, 342) has a constant-diameter segment extending from the tapered segment to the distal end of said adaptor body (314, ,Fig. 6, Fig. 10, ¶0128, 312 next to taper portion 311, ¶0152) and comprising a tubular element (holder 34, 342, ¶0142, made from metal, ¶0028 extending within the constant-diameter segment of the adaptor lumen (342, (Fig. 6) . Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify the adaptor lumen of Mansour to include a tubular element extending within the constant-diameter segment of the adaptor lumen as taught by Enomoto for the purpose of allowing the fluid to pass through the lumen (Enomoto. ¶0129) . Re claim 6, Mansour discloses wherein said adaptor body is formed of a pliable material (¶0190, flexible and compressible) , but it fails to disclose that said tubular element is formed of a material more rigid than the adaptor body material. However, Enomoto discloses an adaptor (3’, Fig. 6-10. 32, 34, 35, ¶0128) and wherein the adaptor has a lumen (341, 342) has a constant-diameter segment extending from the tapered segment to the distal end of said adaptor body (32, ¶0118, made from elastic rubber) and said tubular element is formed of a material more rigid than the adaptor body material. (holder 34, 342, ¶0142, made from metal, ¶0028 extending within the constant-diameter segment of the adaptor lumen (342, (Fig. 6) . Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify the adaptor lumen of Mansour to include a tubular element formed of a material more rigid than the adaptor body material as taught by Enomoto for the purpose of allowing the fluid to pass through the lumen (Enomoto. ¶0129) . Re claim 7, Mansour fails to disclose wherein said adaptor body is an over-molded component that is molded over said rigid tubular element.

Response to Arguments Applicant's arguments filed 8/24/2026 have been fully considered but they are not persuasive. The argument with regards to claim 1 in page 7-10 that Mansour’s device is related to hemolysis- reduction accessories for blood draw. This is found not persuasive as “hemolysis- reduction accessories” was not claimed. The applicant argues that flow restriction of Mansour is as compressible valve member which fails to disclose the limitation “sized, shaped …to fit within a lumen defined through…”. This is found not persuasive as the limitation means that the device is capable to be match in size to connect with a manifold lumen see Fig. 9c, Fig. 14a. The applicant argues to the claim 1 with regards to injection the material ..et. This is found not persuasive as it is capable to deliver/inject the material to the patient see ¶0102. Note the applicant is advised to amend the term “configured” to positively recited limitation such as “the proximal end of the adaptor he injectable treatment material through the manifold.’ The applicant argues with regards to claim 9 in page 9 that a blood is collected with the devices not injected to the adapter. This is found not to be persuasive as in ¶0102 shows that the device is capable to be used in iv delivery system wherein the iv flow in the opposite direction as the blood drawing. The applicant argues with regards to claim 19 in pages 9-10 that a blood is collected with the devices not injected to the adapter. This is found not persuasive as in ¶0102 shows that the device is capable to be used in iv delivery system wherein the iv flow in the opposite direction as the blood drawing. In response to applicant's argument that the examiner's conclusion of obviousness is based upon improper hindsight reasoning, it must be recognized that any judgment on obviousness is in a sense necessarily a reconstruction based upon hindsight reasoning. But so long as it takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made, and does not include knowledge gleaned only from the applicant's disclosure, such a reconstruction is proper. See In re McLaughlin, 443 F.2d 1392, 170 USPQ 209 (CCPA 1971). Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
