    摘要： A myocardial revascularization system that includes a laser energy source (e.g., a semiconductor laser), an outer guide member providing access to a patient's heart, and an optical fiber. The optical fiber is coupled to receive laser energy pulses from the source, is slidably located within the guide member, and is extendible from the distal end of the guide member. A drive motor is connected to the fiber to automatically move the distal end of the optical fiber with respect to the distal end of the guide member. A controller controls the drive motor to automatically move the fiber in synchronism with firing of the laser energy, and automatically calibrates the position of the distal end of the fiber with respect to the distal end of the catheter. The fiber has, at its tip, an enlargened portion with a front surface coated with a heat absorbing material that is nonmetallic and is partially transparent to the pulses. The outer guide member is 7 French or smaller and has a deflectable distal end. A lubricant is located between the optical fiber and an inner lumen surface of the guide member and on the outer surface of the outer guide member. Position sensing components are carried by the optical fiber and outer guide member at or near their distal ends.

    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 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.
