Abstract: An adjustable anchor system provides for securing tissue to bone and includes an anchor with a collapsible suture loop affixed thereto and a tissue suture connected to the collapsible suture loop. After the tissue suture is loaded into the tissue and the anchor implanted into the bone the collapsible loop is collapsed to tension the tissue suture.

Abstract: A surgical stapler includes first and second tissue clamping members and a knife member. The first tissue clamping member is configured to receive a plurality of staples. The second tissue clamping member comprises an anvil configured to form the staples. A tissue treatment member is positionable between the first and second tissue clamping members. The tissue treatment member comprises a rupturable pouch or baffle that is configured to receive a medical fluid including at least one tissue cell. The tissue treatment member may have a spiral shape, an annular disc shape, or an elongate sleeve shape. The tissue treatment member may also include outwardly extending tabs. The tissue treatment member may also include an injection port. In use, the staples and/or the knife pierce the tissue treatment member to release at least a portion of the medical fluid held by the tissue treatment member.

Abstract: A surgical device is operable to coextrude a multilayered biocompatible tissue repair plug in situ within a lumen in a patient. The device comprises a handle, a shaft extending from the handle, a plurality of conduits extending through the shaft, a plurality of media chambers, and an actuator. At least one of the media chambers contains a suspension of at least one tissue fragment having at least one viable cell in a biocompatible carrier. The actuator is operable to cause media in each of the chambers to be urged through, and expelled from the orifice of, the conduit in communication therewith. The orifices are located at the distal end of the shaft such that media from the media chambers may be ejected into a lumen in a patient in order to form a multilayered biocompatible tissue repair plug in situ. The conduits and their orifices are all coaxially aligned.

Abstract: A medical retrieval device for retrieving foreign objects from a patient and the method of constructing the device are disclosed. The device incorporates a wire cable composed of a precursor alloy to a superelastic material to improve durability of the device. Because precursor alloys exhibit, a linear stress-strain relationship and a yield point associated with a relatively high stress level, the device transfers greater stresses before experiencing deformation. Thus, greater crushing forces can be achieved using a device of this type. These crushing forces may be needed when the foreign object is too large to remove intact. This property also facilitates the device in dilating ducts to retrieve foreign objects. Using the precursor alloy additionally eliminates the need for heat treatment of the cables used in constructing the device. A retrieval device made of precursor alloy cable also is less susceptible to permanent deformation and unwinding during use.

Abstract: A suture anchor comprises an anchor body having a proximal end, a distal end, a longitudinal axis and bone engaging external threads oriented for rotation about the longitudinal axis. A longitudinal axial bore extends into the body from its proximal end and at least one lateral passage passes from the axial bore outwardly through the body. A suture attachment element disposed within the axial bore has at least one protruding member having a first position disposed within the axial bore and a second position protruding outwardly from the anchor body through the at least one lateral passage. The protruding member inhibits rotation of the suture anchor body within the bone.
