摘要： A supporting structure for a ligating band dispensing device adapted to be coupled to a distal end of an endoscope comprises a substantially cylindrical outer support surface adapted to receive a plurality of ligating bands thereon, wherein the support surface includes a channel extending therethrough from a distal end to a proximal end. The support surface further includes a plurality of shallow slots and deeper slots disposed on the distal end for retaining a trigger string. The shallow slots and deeper slots may be arranged in an alternating fashion, and each of the slots may be narrower than the trigger string to prevent the trigger string from prematurely exiting the slots. The support surface may also include a plurality of axially extending ridges to assist in deployment of the ligating bands by preventing the bands from sliding along the trigger line and facilitating rolling of the bands along the support surface.

摘要： For weld bonding polymeric components, a bond monitoring device is utilized to sense emissivity from a bonding site to preferably determine the temperature of the material at the surface of the bonding site, in order to provide feedback information to a current generator that controls the thermal energy that is transferred to the bonding site. The bond monitoring device preferably comprises an infrared detector or pyrometer that determines the temperature at the surface of the bonding site by sensing the infrared radiation, which information is used to control current generation. The current generation device preferably comprises a radio-frequency current generator, which RF current is controllably used to create a magnetic field within a magnetic flux concentrator. When used with an mandrel of magnetically permeable material that is positioned close to the magnetic flux concentrator, the mandrel can generate resistive heat based directly on the supply of RF current. The present invention is particularly applicable to weld bonding of tubular type components, such as may be used to make up a medical catheter lumen, because a heatable mandrel can be inserted within a plurality of components having at least adjacently positioned portions that are to be weld bonded together. By carefully monitoring such a weld bonding site and controlling the current generation and thus the heat created by the mandrel, an effective weld bond can be consistently created even where small polymeric components are weld bonded.

摘要： The present invention provides a balloon catheter with a length compensator, which can be an accordion section or a slipping sleeve section. In the accordion section embodiment of the invention, the outer shaft of the catheter includes an accordion section positioned proximally of the balloon. In this embodiment the length compensator is comprised of the accordion section and the outer shaft between the accordion section and the point where the proximal end of the balloon is attached to the outer shaft. The distal end of the balloon is attached to an inner shaft. As the balloon is inflated the accordion section expands to adjust the axial length of the length compensator to compensate for the movement of the two ends of the balloon towards each other. In the slipping sleeve embodiment of the invention, the inner shaft of the catheter includes a slipping sleeve section positioned proximally of the point where the distal end of the balloon is connected to the inner shaft. As the balloon is expanded, the slipping sleeve section contracts, adjusting the axial length of the length compensator to compensate for the shrinkage of the balloon as it expands into contact with the vasculature.

摘要： Balloons for medical devices, particularly balloon angioplasty catheters, are made from particular block copolymer thermoplastic elastomers in which the block copolymer is made up of hard segments of a polyester or polyamide and soft segments of polyether; the polyester hard segments are polyesters of an aromatic dicarboxylic acid and a C.sub.2 -C.sub.4 diol; the polyamide hard segments are polyamides of C.sub.6 or higher carboxylic acids and C.sub.6 or higher organic diamines or of C.sub.6 or higher aliphatic .omega.-amino-.alpha.-acids, and the polyether soft segments are polyethers of C.sub.2 -C.sub.10, diols; the block copolymer has a low flexural modulus, namely less than 150,000 psi; the block copolymer has a hardness, Shore D scale, of greater than 60; and the percentage by weight of the block polymer attributable to the hard segments is between about 50% and about 95%. The polymers provide high strength, thin wall, compliant and semi-compliant balloons, which leads to a low profile catheter. The low profile catheters have very good initial crossing, good trackability, good recrossing after first inflation.

The composite stent portion is comprised of an elongate perfusable vessel supporting portion adapted to be configurable between a reduced size for placement in the vessel and removal therefrom and an expanded size for structurally supporting the vessel and perfusable end portions connected to and forming ends of the vessel supporting portion and adapted to allow fluid flow therethrough. The composite stent portion is comprised of a plurality of resilient metallic wires coated with a polymeric material to provide stability for both lifting and maintaining a vessel. A method is disclosed for deployment of the composite stent to maintain vessel patency during occurrence of an intimal flap, vasoconstriction or vasospasm.

摘要： A delivery system for implantation of a self-expanding stent in a vessel is consists of an elongate flexible catheter for delivering a self-expanding stent to a predetermined location in a vessel. The stent surrounds the flexible catheter near its distal end and is held in a delivery configuration where the stent has a reduced radius along its entire axial length by a stent retaining and release means. The stent retaining and release means is a single layer sheath retaining sleeve means for retaining the stent in its delivery configuration attached to a slipping sleeve means for releasing the stent to self-expand. A balloon may optionally be used to seat the stent in the vessel after self-expansion. The stent may also optionally be retained by water soluble or swelling bands.

摘要： A delivery system for implantation of a medical device in a vessel which has three concentric shafts, an inner shaft for carrying a medical device, a middle pull back shaft and an outer stiffening shaft. The inner and outer shafts are connected together at the proximal end of the delivery system to preclude the inner shaft from moving axially relative to the outer shaft as the middle pull back shaft is retracted. This allows for accurate placement of the medical device.
