Abstract:
An adjustable, knotless button/loop/needle construct for fixation of cranial cruciate ligament deficient stifle. The adjustable, knotless construct includes two fixation devices (for example, two buttons) and at least one flexible, adjustable loop attached to at least one of the fixation devices (e.g., the buttons). Preferably, a needle is attached to each of the fixation devices (e.g., the buttons). The adjustable, knotless construct has an adjustable loop length and allows adjustment in one direction while preventing or locking the construct from loosening in the opposite direction, due to applied tensile forces. The construct and technique of the present invention provides an improved knotless system for cruciate ligament repair.
Abstract:
The invention relates to a system for controlled loading of a reconstructed human or animal tissue during the healing phase, comprising an anchor element (10) for implanting in a first bone (50), at least one connecting element (20), and one retaining element (30) for the at least one connecting element (20) on a second bone (40). The anchor element (10) and/or the connecting element (20) and/or the retaining element (30) are made of self-dissolving bioresorbable material.

Abstract:
The present invention relates to a bone-tendon-bone graft and components. Embodiments of the present invention comprise an intermediate bone block that is used to adjustably secure soft tissue (e.g., tendon) in a patient. Embodiments of intermediate bone blocks of the present invention are used singly or in combination with one or more bone blocks to form a bone block assembly for securing soft tissue. The present invention further relates to an assembled bone-tendon-bone graft for implantation in humans comprising the intermediate bone block and a length of soft tissue. A bone-tendon-bone graft comprises a length of soft tissue extending from a first assembled bone block to a second bone block and then doubles back to said first assembled bone block. Depending upon the embodiment, the second bone block fixedly or slideably attaches to the length of soft tissue and facilitates it doubling back to the first assembled bone block.
Abstract:
A prosthesis for partial replacement of a long bone in humans or animals, the prosthesis including: a proximal or distal end component forming one component of a prosthetic joint; a shaft on or assembled with the distal or proximal end component in use; a stem for engagement in a resected bone; and an initially separate collar assembled to the shaft or an extension thereof in use, the collar being dimensioned to abut the resected end face of the bone into which the prosthesis is to be fitted, wherein the end face of the collar facing the resected face of the bone is sized and shaped to correspond to the resected end face of the bone.
Abstract:
An artificial eye comprises a transparent cup-shaped body member having a substantially concave inner surface and a substantially convex outer surface. The body member includes a pupil portion at the center, a substantially annular iris portion abutting the peripheral edge of the pupil portion for defining a boundary between the pupil portion and the iris portion, and at least one groove formed in the concave inner surface of the iris portion of the body member. The grooves are visible through the iris portion for reflecting light through the body member.
Abstract:
A coated medical device (10) including a structure (12) adapted for introduction into a passage or vessel of a patient. The structure is formed of preferably a non-porous base material (14) having a bioactive material layer (18) disposed thereon. The medical device is preferably an implantable stent or balloon (26) of which the bioactive material layer is deposited thereon. The stent can be positioned around the balloon and another layer of the bioactive material posited over the entire structure and extending beyond the ends of the positioned stent. The ends of the balloon extend beyond the ends of the stent and include the bioactive material thereon for delivering the bioactive material to the cells of a vessel wall coming in contact therewith. The balloon further includes a layer of hydrophilic material (58) positioned between the base and bioactive material layers of the balloon.

Abstract:
The invention concerns a prosthetic element (1) with an outer surface defining an interface to the surrounding bone or fibrous tissue, wherein the prosthetic element (1) is provided with at least one internal anchoring cavity (6) for the growing of tissue and a least one guide means (5) for a cutting tool. The guide means (5) and the anchoring cavities (6) are positioned essentially within the perimeter/circumference of the prosthetic element (1) defined by the outer surface of the prosthetic element (1). The anchoring cavities (6) and the guide means (5) are interconnected and at least one of the anchoring cavities (6) and/or the guide means (5) has an opening in the outer surface for the growing of tissue into the element (1).
Abstract:
The specification discloses a modular system for the formation of a prosthesis for the replacement of a long bone in a human or animal body. The system provides a prosthesis comprising a proximal or distal end component such as a trochanter (1) or condylar head, forming one component of a prosthetic joint, a shaft (5) for assembly with the distal or proximal end component and a stem (8) for engagement in a resected bone. The system allows the assembly of a custom fitted prosthesis from a limited range of components.
