Abstract: An assembly for mounting on a standard mounting platform, such as a Picatinny-type rail, the assembly provides engaged contact between the rail and the surfaces of a base and a clamp. The clamp is rotatably attached to a base, allowing a user to quickly shift the assembly between a rail-engaging position and a disengaged position. The base also preferably contains a locking mechanism that allows a user to lock the assembly in a rail-engaging position. The assembly is particularly useful for the mounting of accessories, such as scopes and sights, onto Picatinny-type rails that are affixed to firearms.

Abstract: A method for treating a body vessel using a stent formed from filaments of titanium or titanium alloys such as Ti—13Zr—13Nb.

Abstract: A stent delivery device having a pair of balloons at a proximal end of a catheter and having separate lumens for selectively inflating the respective balloons. The outer balloon is relatively compliant and the inner balloon is relatively non-compliant. A central lumen is provided for a guide wire. A stent is carried by the delivery device within an axially retractable sheath at the distal end of the catheter and is deployed by retraction of the sheath and inflation of the compliant balloon, and the stent is subsequently expanded by inflation of the non-compliant balloon.

Abstract: Slippery, hydrophilic coating compositions of a polyurethane/urea prepolymer adduct intermediate commingled with at least one dissimilar hydrogel polymer precursor, and materials composed of a polymeric plastic or rubber substrate or a metallic substrate with a slippery hydrogel coating of a polyurethane/urea prepolymer adduct intermediate and at least one dissimilar hydrogel thereon, such that the coating composition tenaciously adheres to the substrate, are disclosed. The coating compositions and coated materials are non-toxic and biocompatible, and are ideally suited for use on medical devices, particularly, catheters, catheter balloons and stents. The coating compositions, coated materials and coated devices demonstrate low coefficients of friction in contact with body fluids, especially blood, as well as a high degree of wear permanence over prolonged use of the device.

Abstract: A balloon catheter which is assembled by a process of selectively concentrating laser energy along an annular fusion bond site at contiguous surface portions of a length of catheter tubing and a shaft or neck portion of a dilatation balloon. The laser energy wavelength, and the polymeric materials of the balloon and catheter, are matched for high absorption of the laser energy to minimize conductive heat transfer in axial directions away from the bond site. This minimizes crystallization and stiffening in regions near the bond site, permitting fusion bonds to be located close to the proximal and distal cones of the dilatation balloon while preserving the soft, pliant quality of the cones.

Abstract: A shipper package for shipping sliced meat and the like is disclosed in which a substantially ridged base is formed with a ridge which defines a target area for the location of a meat product thereon. The ridge is interrupted at at least one point about the periphery of the target area to provide a peripherally extending gap which extends to the surface of the platform on which the meat product is to be supported such that the full height of the product above the support platform can be ascertained visually through the gap in the ridge. A transparent wrapper encloses the product and seals the product with respect to the base.
