Therefore, it would be prima facie obvious, before the effective filing date of the present invention, to modify the method of Maguire with similar electrode positions as taught by Paassilta for the purpose of detecting the position of the injection needle ([0084-0086]).
Maguire/Paassilta are silent wherein a set of lumen holes of the needle are located between the first and second electrochemical impedance sensors.
Schwartz teaches a method wherein a set of lumen holes (end holes 68, Fig 13)of the needle are located between the first and second electrochemical impedance sensors ([0075]: first electrode at the needle tip and a second electrode spaced apart; additional electrodes could be used to determine the depth of the injection which would include a greater distance than the tip of the needle; holes 68 will lie between the first and second electrode; Fig 13).
Therefore, it would be prima facie obvious, before the effective filing date of the present invention, as taught by Schwartz while maintaining the electrodes position Maguire/Paassilta for the purpose of adjusting the flow rate of the injection to a desired value base on the selected diameter of the holes (Abstract: “create a desired injectate cloud pattern when an injectate is forced through the central lumen and through the plurality of holes”).
Claims 10, and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Maguire et al. (US 20150065916 A1) in view of Peters (US 20060129184 A1).
Regarding claim 10, Maguire discloses the method of claim 1 further. Maguire is silent regarding comprising a pressurized space around the injection position; and sterilizing the pressurized space around the injection position.
