US Classification:

606144000, 606222000

Abstract:

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.

International Classification:

A61B 17/04

US Classification:

606232

Abstract:

Some embodiments of the present invention include a suture anchor with both knotless and knotted suture attachment capabilities, as well as methods for loading the suture in knotless and knotted configurations. Some embodiments of the present invention include a suture anchor with an inner implant body with a spreader that slides in relation to an outer expandable collar, such that pushing the expandable collar distally with an inserter causes the spreader to expand the collar against the surrounding bone to secure the suture anchor in place. Such embodiments may also include a detachment or breakaway feature between the inserter and the suture anchor to permit separation after anchor deployment. Some embodiments of the present invention include methods for deploying such suture anchors and expanding the expandable collars and/or detaching the inserter tools. Embodiments of the present invention may be used in various orthopedic applications such as, for example, shoulder repair.
