Assignee:

Ethicon, Inc. - Somerville NJ

International Classification:

A61B017/04

US Classification:

606232, 606 72, 606228

Abstract:

A suture anchor for affixing soft tissue to bone. The anchor has a hollow outer member, and an actuation member slidably mounted within the outer member. The actuation member has at least two engagement members that are pivotally mounted to the actuation member. Proximal movement of the actuation member with respect to the outer member causes the engagement members to move outward to a deployed position, wherein the engagement members are deployed in bone. A surgical suture is mounted to the anchor.

Ethicon, Inc. - Someriville NJ

International Classification:

A61B 17/06

US Classification:

606144

Abstract:

A needle passer instrument for use in minimally invasive surgical procedures, including arthroscopy. The instrument has upper and lower jaws for engaging tissue and a handle. A removable needle engaging cartridge is mounted to the upper jaw. A surgical needle with attached suture is mounted in a needle passage in the lower jaw. A needle actuation rod engages the surgical needle and pushes the needle through tissue contained between the jaws. The needle is engaged by the cartridge, and the needle may be cut away from the suture.

International Classification:

A61B 17/00

US Classification:

606 1

Abstract:

An implant manipulator may have a distal end that retains an implant, a proximal end, and an intermediate portion between the ends. The intermediate portion may have a cross-sectional shape that extends along a nonlinear pathway. The intermediate portion may have a selectively bendable portion in which the cross-sectional shape varies to facilitate bending when desired. The implant manipulator may be a needle for a suture passer, with a suture capture feature at the distal end. The suture capture feature may have first and second members that flex apart to permit entry of the suture into a suture capture hole wherein the suture is retained until released. A suture passer may receive the needle in a bore shaped to change the cross-sectional shape to facilitate or restrict bending of the needle, as needed.

International Classification:

A61B 1704

US Classification:

606232

Abstract:

A connector for joining sections of flexible material includes inner and outer members that snap fit together by passing the bore of the outer member over the inner member to capture and secure ends of flexible material such as sutures. The flexible material is fitted into a bore in the inner member and project out a side portal to pass between the shared or opposing inner and outer member surfaces. This serpentine pathway locks the flexible material in place. The invention further provides a delivery instrument to maintain the outer member in alignment with a receiving end of the inner member loaded with flexible material. The delivery instrument further includes cooperating elements for urging the outer member over the inner member to lock the flexible material in place.
