Abstract: Devices and methods for storing and injecting a corneal tissue graft are disclosed herein. In one embodiment, an apparatus includes a tissue container and an adaptor configured to be coupled to the tissue container. The tissue container defines an interior region configured to receive a precut corneal tissue graft therein. The tissue container is also configured to be coupled to an injector assembly that can be used to move the corneal tissue graft out of the interior region of the tissue container and into an anterior chamber of a recipient's eye. The adaptor can be configured to prevent the tissue graft from migrating out of the tissue container and/or can be configured to be coupled to the injector assembly. The tissue graft can remain within the tissue container during storage, transport and during the implantation procedure until it is injected into the patient's eye.

Abstract: A platinum enhanced radiopaque alloy particularly suitable for manufacture of implantable and/or intravascular medical devices. A stent is one preferred medical device which is a generally tubular structure that is expandable upon implantation in a vessel lumen to maintain flow therethrough. The stent is formed from the alloy which has improved radiopacity relative to present utilized stainless steel alloys. This alloy preferably contains from about 2 wt. % to about 50 wt. % platinum; from about 11 wt. % to about 18 wt. % chromium; about 5 wt. % to about 12 wt. % nickel and at least about 15 wt. % iron.

Abstract: Nut or bolt head holding tweezers which are engageable with nut or bolt heads and is formed from either metallic or polymeric material and includes a pair of substantially parallel legs that extend from a proximal joint end. One of the legs of the nut or bolt head tweezers is formed with partial polygonal jaw with the other leg having an opposing partial polygonal jaw. Furthermore, the tweezers are fitted with a locking slide that when moved in the distal direction, flexing said legs together and secures the nut or bolt head between said partial polygonal jaws. Thereby facilitating the ability to successfully secure and position a nut or bolt in an area with difficult accessibility.

Abstract: Bead or weight holding tweezers which are engageable with beads and beads or weights and is formed from either metallic or polymeric material and includes a pair of substantially parallel legs that extend from a proximal joint end. One of the legs of the bead or weight tweezers is formed with an inwardly directed concave member which has a friction bearing surface that, together with a substantially flat surface of the other leg, will fixedly engage to a bead or weight. Furthermore, the tweezers are fitted with a locking slide that when moved in the distal direction, flexes said legs together and holds the bead or fishing weight between said concave portions. Thereby facilitating the ability to successfully slide the bead or weight onto a desired position on the hook.

Abstract: A metallurgical process for producing a metallic implantable medical device, such as a stent, in a condition wherein the metallic alloy of the device has improved mechanical properties. The starting material is formed into an oversized tube which is drawn to finished outer diameter. The drawing process cold works the tube to produce a material having a high dislocation density and a yield strength that is above approximately 125 ksi. Next, the drawn tube is heat treated at a temperature of approximately one-half the absolute melting temperature of the alloy. The heat treatment causes dislocations to rearrange, forming sub-grains and re-crystallization of the grain structure. Upon cooling, a material is obtained having a yield strength between approximately 45-70 ksi and an elongation exceeding 40 percent. The material also has good resistance to fatigue fracture due to the fine grains and sub-grains that are established during the heat treatment.

Abstract: An apparatus for imprinting a stent configuration image from a mask form onto a tubular stent blank. The stent blank has a longitudinal axis and a photosensitive coating on the outer surface thereof. The apparatus includes a journaling mechanism adapted to receive the stent blank, and operable to rotate the stent blank about its longitudinal axis; a radiation source operable to direct light at a first surface region of the stent blank when mounted in the journaling mechanism, to thereby expose the photosensitive coating on said first surface region of the stent blank; and a mask form movement mechanism configured to mount the mask form in the apparatus and to move the mask form along a path in which the mask form contacts the stent blank in said first surface region thereof along a concurrent convex arcuate segment.

Abstract: Disclosed herewithin is an apparatus for fabricating a stent which involves processing a tubular member whereby no connection points to join the edges of a flat pattern are necessary. The process includes the steps of: a) preparing the surface of a tubular member, b) coating the outside surface of the tubular member with a photo-sensitive resist material, c) placing the tubular member in an apparatus designed to simultaneously rotate the tubular member while passing a specially configured photographic frame negative between a light source and the tubular member, d) exposing the tubular member to a photoresist developer, e) rinsing the excess developer and uncured resist from the exposed tubular member, f) sealing the inner lumen of the tubular member, and g) treating the tubular member with a chemical or electro-chemical process to remove uncovered metal. By modifying the photographic negative, this process can be employed to fabricate a virtually unlimited number of stent designs and configurations.
