An orthopaedic implant includes an implant body comprising a biocompatible material and configured to be implanted at an anatomical location, the implant body defining a surface; and a porous material at least one of attached to and integral with the surface of the implant body, the porous material having a plurality of grooves formed therein.

A polymer is composed of a linear chain acrylate and a multi-functional acrylate cross-linker. The polymerized composition exhibits a transition at a temperature between about 34° C. and about 50° C. The polymerized composition exhibits shape memory effects. In one embodiment, the linear chain is tert-butyl acrylate and the crosslinker is polyethylene glycol dimethacrylate. The resultant shape memory polymers may be used in medical devices to provide devices with different shapes for pre and post implantation.

A surgical method is provided, the method including the steps of: providing an artificial or allograft flexible planar structure; providing an implant, the implant including material liquefiable by mechanical oscillation, exposing a surface region of hard tissue or hard tissue substitute material; positioning the implant on an exposed area of the hard tissue or hard tissue substitute material; and fastening the implant to the hard tissue or hard tissue substitute material by impinging the proximal end of the implant with mechanical oscillation and simultaneously pressing the implant against the hard tissue or hard tissue substitute material while the distal end of the implant protrudes into a cavity of the hard tissue or hard tissue substitute material and regions of the liquefiable material are in contact with the hard tissue or hard tissue substitute material, and thereby liquefying at least a portion of the liquefiable material, and letting the liquefiable material resolidify.

An implantable and removable filter that may be implanted in and/or removed from a body lumen, such as the Vena Cava. The filter including tissue anchors on expandable anchoring legs, which can be selectively moved between a non-anchoring or pre-deployed configuration into an anchoring or deployed configuration by obturators that are movable inside the anchoring legs.

Tissue repair systems which use knotless all-suture anchors and have the ability to lock multiple repair sutures within the anchor construct. The anchor construct includes a tension suture wrapped or looped upon itself to create an open eyelet, through which multiple repair sutures originating in soft tissue are passed. The location of the eyelet may be anywhere inside the all-suture anchor or adjacent to the exterior of the anchor body. Tensioning of the tension suture causes the eyelet to restrict movement of the repair sutures and secures them within or against the anchor body.

Anterior cruciate ligament reconstruction methods and devices are designed to achieve an anatomically accurate double bundle anterior cruciate ligament reconstruction by using a single femoral and tibial tunnel. The method and devices reconstruct the two bundles of the anterior cruciate ligament in a single femoral and tibial tunnel using a bone-patellar tendon-bone graft. The methods and devices enable an accurate anatomical reconstruction of the anteromedial and posterolateral bundles by creating a single femoral and tibial tunnel as opposed to creating two tunnels in the tibia and femur.

An apparatus and method for the repair of disruptions between bones. The apparatus defines a combination of sleeves, strands and crimps are provided to secure the bones, using a dual sided drill guide to prepare the bones for installation of the apparatus, which is adjusted upon installation to suit the appropriate alignment and tension of the apparatus. The method includes the preparation of the bones, the installation of the apparatus and the adjustment of the apparatus to properly align and tension the apparatus for repair of the bone.

Apparatuses for attaching tissue to bone are provided. In one exemplary embodiment, the apparatus includes an expandable body defining a bore, an expander pin having a shaft sized to be received in the bore of the expandable body, and an insertion shaft slidingly disposed in the bore of the expandable body and in a bore of the expander pin. The body is configured to expand laterally into and attach to bone when the expander pin is driven into the expandable body. The body includes a proximal main member having a distally extending threaded projection and a harder, distal tip member having a threaded recess in a proximal surface thereof such that the projection is threadedly interengageable with the recess. The expansion of the body by way of the pin can occur when the proximal main member and distal tip member are threadedly engaged. The insertion shaft is releasably secured to the expandable body and extends distally beyond the expandable body.

A bone suture assembly including a flexible generally cylindrical sleeve, a plurality of lengths of suture extending through the generally cylindrical sleeve, and at least one sleeve securing thread associated with the generally cylindrical sleeve. A bone suture retaining method including engaging a suture with a bone engaging sleeve, inserting the suture and the bone engaging sleeve engaged thereby into a transosseous tunnel formed into a bone by pulling the bone engaging sleeve into the transosseous tunnel and retaining the suture and the bone engaging sleeve in the transosseous tunnel by virtue of the bone engaging sleeve being unable to fit through an aperture in the bone.

A ligament fixation method can include forming a bone tunnel to a predetermined depth from a surface of a bone; mounting a reconstruction ligament to the ligament fixation device. The reconstruction ligament can be disposed along outer surfaces of plate-like pressing segments of a ligament fixation device and an outer surface of a connection segment that connects the pressing segments. The method can also include inserting the ligament fixation device into the bone tunnel from the connection-segment side; fastening a screw to a receiving section of the ligament fixation device from an opening of the ligament fixation device to increase a distance between the pair of pressing segments and to compress the reconstruction ligament between each pressing segment and an inner surface of the bone tunnel; and fixing the reconstruction ligament to the bone by causing a part of the screw to dig into the bone.
