Abstract: A multi-suture knotless anchor and related method for securing soft tissue, such as tendons, to bone are described. The suture anchor includes a body, a sleeve, and an outer deformable bone locking structure. The bone locking structure has a first low profile configuration for insertion into the bone, and a second larger profile configuration for engaging the bone when actuated. The bone anchor and methods permit a suture attachment that lies beneath the cortical bone surface and does not require tying of knots in the suture.

Abstract: An innovative bone anchor and methods for securing soft tissue, such as tendons, to bone, which permit a suture attachment that lies entirely beneath the cortical bone surface. The suturing material between the soft tissue and the bone anchor may be secured without the need for tying a knot. The suture attachment to the bone anchor involves the looping of a length of suture around a suture return member or path within the bone anchor, tightening the suture and attached soft tissue, and compressing the suture against the bone anchor. The bone anchor may be a tubular body having a lumen with a locking plug that compresses the suture therein. One of the components of the locking structure may include a deformable or flexible section, member, or surface. The locking plug may include a shaft and an enlarged head that interferes with the tubular body to provide a positive stop.

Abstract: A knotless suture lock and bone anchor wherein a suture, looped through a tissue, is threaded through a plurality of body holes in the anchor to cinch the suture and tissue to the anchor without tying a suture knot on the tissue, and wherein the anchor is adapted for embedding in a bone. The tissue is secured to the anchor by suturing the tissue without a suture knot, fastening the standing leg portion of the suture on a suture leg-anchoring structure, and threading the working leg portion of the suture through the body holes. Pulling on the working leg portion of the suture tightens the suture on the body structure and cinches the loop without a suture knot on the tissue. The bone-embedding structure comprises a plurality of barbs adapted to resist pullout of the anchor from the bone.

Abstract: A suture-loading system, method and apparatus for loading a suture onto a bone anchor, the system comprising: a bone anchor comprising a suture leg-anchoring structure and a plurality of body holes on the anchor; a suture comprising a standing end portion and a working end portion; a standing end trackway to guide the standing end portion of the suture through the suture leg-anchoring structure; and a working end trackway to guide the working end portion of the suture through the body holes in the anchor.

Abstract: A suture-locking apparatus comprising a body member having a proximal end, a distal end, and an axial lumen in between the proximal and distal ends, wherein the proximal end adapted for passing a portion of a suture into the lumen; and a plug member movable from a first position to a second position in the lumen, the plug member comprising a radial protrusion adapted for compressing the suture against the body member on moving to the second position. In a further embodiment the invention is a method of anchoring soft tissue in a body cavity with a suture using the present apparatus and without tying a knot.

Abstract: A vacuum-assisted venous drainage reservoir for cardiopulmonary bypass surgery with both hard and soft shell reservoirs. The system utilizes a wall vacuum or other source of negative pressure to create a negative pressure via a regulator within a sealed hard shell reservoir, or within a sealed housing surrounding a soft shell reservoir. The addition of a negative pressure in the venous return line enables the use of smaller cannulas suitable for minimally invasive surgery. The reservoir need not be positioned well below the patient as in conventional gravity venous drainage configurations, thus adding flexibility to the operating room layout and enabling a reduction in the extracorporeal blood prime volume needed. In one embodiment, a flexible membrane in the hard shell reservoir expands to contact the blood surface and reduce blood/air interactions. In another embodiment, a moisture trap is provided between the source of vacuum and hard shell reservoir to reduce environmental contamination.
