International Classification:

A61B 17/58
A61B 17/60
A61F 2/00

US Classification:

606102, 606 86 R, 606 90

Abstract:

A tensor/ligament balancer for use in measuring a gap existing between an anatomy is provided. The tensor/ligament balancer can include a first paddle. The tensor/ligament balancer can also include a second paddle movable relative to the first paddle. The tensor/ligament balancer can further include a biasing member operable to apply a substantially constant force on the second paddle to move the second paddle relative to the first paddle. At a first position, the second paddle can be substantially adjacent to the first paddle. The second paddle can be automatically movable away from the first paddle to a second position by applying the substantially constant force to the second paddle.

International Classification:

B28B 3/10

US Classification:

264667

Abstract:

A ceramic implant having a rough surface texture and a method for forming the same. The method includes forming a green body of a first ceramic composition. The green body is reduced to smaller pieces thereby forming ceramic fragments. A mold is filled with a second ceramic composition to form a ceramic base. Ceramic fragments are added to the mold and an outer layer is formed over at least a portion of the ceramic base. Pressure is applied to the mold to compress the outer layer onto the ceramic base and to form a green assembly. The green assembly is sintered to form a ceramic implant having a rough surface texture.

International Classification:

A61B 17/04

US Classification:

606232

Abstract:

An anchor for securing tissue to bone can include a flexible first tubular member, a flexible second tubular member, and a first suture member. The first tubular member can include a first wall defining a first passage between first and second ends. The second tubular member can include a second wall defining a second passage between first and second ends. The first suture member can couple the first tubular member and the second tubular member. The first suture member can pass through the first wall and the first passage and the second wall and the second passage. The first tubular member and the second tubular member can engage each other and deform to form an anchoring mass upon tensioning the first suture member. A method of preparing an anchor for securing tissue to bone and a method of securing a tissue to a bone are also provided.

Assignee:

Biomet Sports Medicine, LLC - Warsaw IN

International Classification:

A61B 17/04

US Classification:

606232

Abstract:

A method can include forming a bore in a bone of a patient and positioning a first anchor in the bore. The first anchor can have a self-locking adjustable suture construct extending therefrom that can include first and second adjustable loops. The first adjustable loop can be positioned about a first portion of the soft tissue and the second adjustable loop can be positioned about a second portion of the soft tissue different than the first portion. A coupling element carried by the second adjustable loop can be coupled to the first adjustable loop. An end of the adjustable suture construct can be tensioned to reduce a size of the first and second adjustable loops to couple the soft tissue to the bone.

International Classification:

A61B 17/62

US Classification:

606 56

Abstract:

A polyaxial pivot housing for an external fixation system, comprising a collet body having a threaded portion; a spherical member configured to be partially received by a cavity that is formed in the collet body, the spherical member having a threaded post that is configured to attach to a support member of an external fixation frame; and a threaded locking collar that is configured to orientationally lock the threaded post with respect to the external fixation frame by compressing the spherical member into the cavity as the threaded locking collar is mated with the threaded portion of the collet body.
