  • Patent number: 7713284
    Abstract: A tissue closure apparatus having a collar, a pair of elastically deformable legs, and a flexible adjustment member is provided. The collar includes a collar wall defining a passage therethrough, along which are disposed a plurality of teeth extending outward into the passage. A pair of elastically deformable legs is connected to the collar, and each leg includes a lateral portion adjacent the collar and an engagement portion connected to the lateral portion. A flexible adjustment member is connected to the engagement portion of at least one of the elastically deformable legs. The flexible adjustment member is disposed within the passage of the collar and includes a plurality of teeth to engage the plurality of teeth of the collar.

  • Patent number: 7695474
    Abstract: A femoral neck fixation prosthesis and method of using same which reduces bone loss and the avoids the other shortcomings of the prior art by allowing the fixation of a stable femoral head replacement while reducing the amount of the femur which must be reamed for the insertion of the prosthesis. The preferred embodiment provides that the femoral head is attached to a fixation prosthesis, which extends coaxially through the canal of the femoral neck, into the femur, and is then attached to the opposite lateral wall of the femur. In this manner, the prosthesis serves to imitate the original structure of the femoral neck. No other support members, either crosspins or arms extending into the length of the femur, are required.
