    摘要： A mixing system and method for forming bone cement by mixing liquid monomer methyl methacrylate (MMA) with a powder component comprising polymethyl methacrylate (PMMA). A container of MMA is received in a bag. The MMA is emptied from the container into the bag, and a syringe is connected to the bag in substantially leak-free manner to receive the MMA from the bag. The syringe is disconnected from the bag and thereafter connected to a receptacle housing the powder component. The MMA is then transferred into the receptacle in substantially leak-free manner.

    摘要： A delivery system is provided with a balloon catheter having a stent mounted thereon. A retention wire is provided to restrain the stent on the balloon of the balloon catheter. The retention wire is coupled to the catheter adjacent the distal end of the stent and adjacent the proximal end of the stent. The retention wire extends along the length of the stent adjacent the outer surface thereof. Thus, the retention wire may restrain the stent from moving longitudinally during inflation of the balloon.

    摘要： An introducer apparatus and a method for forming an introducer apparatus. The apparatus comprises an inner liner having a passageway extending longitudinally therethrough. A coil in a stressed, radially expanded condition is positioned longitudinally around said inner tube. A polymeric outer tube is positioned longitudinally around the coil and the inner liner, and is bonded to the inner liner through the spaces between the turns of the coil. The polymeric outer tube is formed in a manner such that it maintains the coil in its stressed radially expanded condition. In a preferred embodiment, the inner liner and outer tube comprise a polyimide.

    摘要： An epidural catheter is disclosed having a durable and a flexible segment joined together. The flexible segment is inserted into a patient with the use of a well-known needle which is removed by passing the needle over the outside of the catheter. The flexible segment is atraumatic to the surrounding tissue. The flexible segment includes a plastic tube surrounded by a wire coil for pushing the tube into a passageway of the tissue. The distal end of the plastic tube and wire coil are joined to prevent unwinding of the coil when extracted. The tightly coupled wire coil also permits the flexible portion to be easily inserted into the passageway of the tissue. The durable segment joined to the flexible segment includes a stainless steel tube with a flat wire coil surrounding a length of the tube. The stainless steel tube permits fluid at an elevated pressure to pass through the hollow passageway therein without rupturing. The flat wire coil prevents kinking of the semi-rigid stainless steel tube. When a fluid at an elevated pressure is received, the distal end of the flexible tube is closed to diffuse the fluid passing through the length of the catheter. Slits are provided laterally on the side of the plastic tube for emitting and diffusing the fluid through the wire coil.

    摘要： Disclosed is an anchoring element for an implantable prosthesis that includes a barb, wherein the anchoring element, which includes a basal portion, comprises a thin layer of material, such as a cannula or sheet of metal, that extends or wraps at least partially around the strut of the prosthesis to which it is attached. The barb is configured to extend outward from the basal portion to penetrate adjacent tissue. The anchoring element is either permanently affixed to the strut, such as by laser or spot welding, crimping, or some other method of bonding, or allowed to slide longitudinally over the strut between two points or stops in order to relieve any excessive loads placed upon the barb that could cause fracture. The anchoring element and strut may be configured to limit axial rotation of the barb, while still allowing longitudinal movement. In another embodiment, the slidable anchoring element may be manipulated following initial deployment to reorient the barb toward the implantation site.
