    摘要: A method of forming intra-aortic balloons includes forming a balloon blank having a sleeve section at its proximal end. To reduce the diameter of the sleeve section of the balloon, the sleeve section is stretched longitudinally by gripping a first portion of the balloon blank at the distal end of the sleeve section, gripping a second portion of the balloon blank at the opposite end of the sleeve section and moving at least one of the gripped portions away from the other so as to reduce the diameter of the sleeve section. A heating element is positioned within the sleeve section to relieve the stress in the sleeve after stretching, by heating the sleeve section. The sleeve section is then cooled in order to preserve the sleeve section in its reduced diameter state thereby forming an intra-aortic balloon having a balloon blank with a reduced diameter sleeve section.

    摘要: An intra-aortic balloon pump catheter includes an inner lumen formed by a thin walled superelastic metal alloy tube, namely of nitinol, with an inside diameter sufficient for a guidewire and a small outside diameter which allows reduction of the outer lumen and related components by at least one size French while providing gas shuttle capacity between the lumens for conventional intra-aortic balloon pump operation. The outer lumen is a tube formed of co-extruded plastics to enhance the size reduction and capacity goals, with an inner nylon portion for strength and a relatively thin polyurethane outer portion for biocompatability, flexibility and compatibility for bonding to a thin polyurethane balloon. The proximal end sleeve of the balloon is stretched and then stress-relieved by heating with an internal heater on a mounting mandrel to effect a desired small diameter sizing. A radiopaque metal marker ring of nitinol also is provided to improve imaging capabilities while being compatible with the lumen materials.

    摘要: An intra-aortic balloon packaging sheath is provided which includes a long slim extruded plastic tube for storing a furled thin-walled intra-aortic balloon. An entry section of the same plastic is injection molded onto one end of the tube, with the entry section including an outwardly flared entry port surface which is spaced from one end of the tube, and an internal passageway which is co-linear and congruent with the internal cross-section of the tube from the respective end of the tube through the intersection of the second internal passageway with the outwardly flared passageway. Thereby a smooth internal surface is provided through the flared passageway into the internal passageway and through the later into the tube. The exit end of the sheath tube is inverted by use of a heated tipping die such that a distal end portion is turned outwardly and back circumjacent another portion of the tube wall to form a smoothly rounded exit passageway of the tube at the exit end.

    摘要: Biodegradable polymer-coated surgical meshes formed into pouches are described for use with cardiac rhythm management devices (CRMs) and other implantable medical devices. Such meshes are formed into a receptacle, e.g., a pouch or other covering, capable of encasing, surrounding and/or holding the cardiac rhythm management device or other implantable medical device for the purpose of securing it in position, inhibiting or reducing bacterial growth, providing pain relief and/or inhibiting scarring or fibrosis on or around the CRM or other implantable medical device. Preferred embodiments include surgical mesh pouches coated with one or more biodegradable polymers that can act as a stiffening agent by coating the filaments or fibers of the mesh to temporarily immobilize the contact points of those filaments or fibers and/or by increasing the stiffness of the mesh by at least 1.1 times its original stiffness. The pouches of the invention can also provide relief from various post-operative complications associated with their implantation, insertion or surgical use, and, optionally, include one or more drugs in the polymer matrix of the coating to provide prophylactic effects and/or alleviate side effects or complications associated with the surgery or implantation of the CRM or other implantable medical device.
