An elbow prosthesis according to the present teachings can include a stem structure and an articulating component. The stem structure can be operable to be positioned in a bone of a joint. The stem structure can include a stem portion that is operable to be positioned in the bone and a C-shaped body portion having a first retaining mechanism formed thereon. The articulating component can have a second retaining mechanism formed thereon. One of the first and second retaining mechanisms can comprise an extension portion and a first anti-rotation portion. The other retaining mechanism can comprise a receiving portion and a second anti-rotation portion. The articulating component can be advanced from an insertion position to an assembled position, such that the first and second mechanisms cooperatively interlock to inhibit translation and rotation of the articulating component relative to the C-shaped body portion of the stem structure.

An endoluminal device can be configured for precise positioning during deployment within a vessel. The endoluminal device can be a tack, stent, vascular implant or other type of implant. The endoluminal device can have circumferential member with an undulating configuration having multiple inward and outward apexes and struts extending therebetween. Two of the struts can be used to establish a foot for the precise positioning of the device during deployment. A method of placing the endoluminal device can include withdrawing an outer sheath such that a portion of the endoluminal device is expanded prior to the rest of the endoluminal device.

An implant system for providing stabilized fixation of tissue includes a button having a slot, a band threaded through the slot, and a lock including a member having a slot for receiving an end of the band and a movable member for clamping the band in place. The movable member is movable between an open position and a locking position. The lock is a plug assembly which includes a flange. The slot is disposed in the flange. The movable member may be a cap which is movable between clamping and non-clamping orientations relative to the flange, or it may be a screw wherein a portion of the screw performs the clamping function. The flange is a portion of a plug, which plug further includes a boss extending from one side of the flange.

A system for delivering a surgical staple can include various components. The system may include an elongate body with a proximal end, a distal end, and a plurality of delivery platforms disposed adjacent the distal end. A sheath can move relative to the elongate body from a first position in which the distal end of the sheath is disposed distally of a distal-most distal delivery platform to a second position in which the distal end of the sheath is disposed proximally of at least one delivery platform. A plurality of intravascular tacks can be within the system with each disposed about a corresponding delivery platform.

A system for repairing a defect on an articular surface of a patient's trochlear region, the system comprising a guide block comprising a body having an exterior surface configured to engage with the saddle portion and ridge portions of the patient's trochlear region, a protrusion extending generally from the body and configured to be received in a first bore formed in the articular surface along a reference axis, and a first cavity extending through the body configured to establish a first working axis displaced from the reference axis, wherein the exterior surface of the body and the protrusion are configured to secure the location of the guide block about the patient's trochlear region. A method for preparing an implant site in bone, comprising: establishing a reference axis extending from the bone; creating a bore in the bone by reaming about the reference axis; securing a guide block about the articular surface; establishing a first working axis extending from the bone using the guide block, the first working axis is displaced from the reference axis; and creating a first socket in the bone by reaming about the first working axis, wherein the first socket partially overlaps with the bore.

An elbow prosthesis according to the present teachings can include a stem structure and an articulating component. The stem structure can be operable to be positioned in a bone of a joint. The stem structure can include a stem portion that is operable to be positioned in the bone and a C-shaped body portion having a first retaining mechanism formed thereon. The articulating component can have a second retaining mechanism formed thereon. One of the first and second retaining mechanisms can comprise an extension portion and a first anti-rotation portion. The other retaining mechanism can comprise a receiving portion and a second anti-rotation portion. The articulating component can be advanced from an insertion position to an assembled position, such that the first and second mechanisms cooperatively interlock to inhibit translation and rotation of the articulating component relative to the C-shaped body portion of the stem structure.

A multi-piece IOL assembly is provided that includes a platform and an optic. The platform has an inner periphery surrounding an inner zone of the platform. The optic has an optical zone, an outer periphery and a retention mechanism disposed on the outer periphery. The optic is configured to be disposed in the inner zone of the platform and to extend to a location between the inner periphery and the outer periphery of the platform to be secured to the platform at the location. The platform can be secured to an inner periphery of the eye or can be formed into a natural lens by cutting the lens using a laser or other energy source.

An alloplastic implant for bridging osteotomy border gaps and irregularities in a mandible body. The alloplastic implant has an implant body of biocompatible, alloplastic material with a substantially J-shaped profile contour. The implant body has a vertical component with a substantially flat surface for being disposed toward a face surface of the mandible body, a lateral component that is semi-circular in profile and that mimics a contour of the inferior border of the mandible body, and a transverse component. The implant body is dimensioned to bridge border gaps and irregularities in the mandible body in a method for bridging such gaps and irregularities with the vertical component positioned to span a portion of the face surface of the mandible body and the lateral component positioned to overlie the inferior border of the mandible body. Immobilization of the implant body relative to the mandible body can be achieved by mechanical fastening.

Disclosed herein are elastic, bioresorbable encasements for medical implants, methods for making the same and uses thereof.

A dissection prosthesis system for implantation within a blood vessel includes a first prosthesis and a second prosthesis. The first prosthesis includes a first stent ring, a second stent ring, a first graft material band coupling the first stent ring to the second stent ring, a third stent ring, and a second graft material band coupling the second stent ring to the third stent ring. The second stent ring includes a plurality of openings that enable fluid flow from a lumen of the first prosthesis through the plurality of openings. The graft material bands may include band openings disposed therethrough to enable fluid flow from the lumen through the band openings. The second prosthesis includes a stent coupled to a graft material. The second prosthesis is configured to be disposed within the lumen of the first prosthesis.
