Suture needle, suture needle/suture assembly and suture passer device

摘要

A blade suture needle is adapted for use in a suture needle assembly, and with a suture passer device, for passing a suture needle assembly through tissue. The suture needle includes an elongated resilient sheet body member bounded by opposite principal surfaces. The body member includes at least one central aperture extending between the principal surfaces, having dimensions to permit of a capturing flange to pass therethrough. The suture needle may be part of a needle assembly further including an elongated suture passing through an aperture in the needle. A suture passer device includes an elongated pusher guide with pair of opposed jaw members disposed at its distal end, which may be opened or closed in response to a user action at its proximal end. The guide allows passage of an elongated pusher element through a pusher channel therein. One of the jaw members includes a suture assembly channel aligned with the pusher channel. The other jaw member has an aperture passing therethrough, which is aligned with the suture assembly channel when the jaw members are closed. This other jaw member includes an elongated resilient flange fixedly or retractably attached to the jaw member at the periphery of the aperture, and extending across the aperture to an opposite point on the periphery of the aperture.
