摘要： A dilation catheter suitable for use in medical procedures is provided which includes a balloon disposed on an elongated flexible tube. The tube is capable of passing fluid between the balloon and the tube for varying the balloon between a collapsed and expanded condition. The catheter includes a brace fitted over the balloon for restricting expansion of a selected portion of the balloon for forming a perfusion channel that allows fluid to be perfused past the balloon when it is expanded in a body vessel. A medical procedure for dilation under perfusion conditions is also provided.

摘要： A dilation catheter suitable for use in medical procedures is provided. The catheter includes a balloon disposed on an elongated tube. The tube is capable of passing fluid between the balloon and the tube for varying the balloon between an inflated expanded condition and a deflated collapsed condition. The balloon includes a longitudinally extending spiral wall which forms a longitudinally extending spiral channel spaced inwardly from the exterior surface of the balloon when the balloon is in its expanded condition to allow fluid to be perfused past the balloon.

摘要： A guidewire navigable through body vessels of a human subject for delivery of a catheter or the like is provided. The guidewire includes an expandable segment movable between a collapsed state and an expanded state. If the catheter encounters resistance in a vessel and cannot be advanced further, the medical professional can move the expandable segment to the expanded state in which the expandable segment engages an inner surface of the catheter. The expandable segment locks onto the catheter, which allows the guidewire and catheter to be advanced through the vessel together as a single unit. An inflatable balloon catheter movable along the guidewire requires only a single tube and is sealed by the expandable segment of the guidewire for subsequent inflation.

摘要： Apparatus for facilitating balloon catheter exchange in a vascular dilatation procedure using a balloon guidewire emplaced within the vascular system of a patient, and a balloon catheter defining an inflation lumen and a guidewire lumen and being attached at its proximal end to a hub. The apparatus includes a relatively short guidewire extension attached at its proximal end to a handle portion. The handle portion defines structure cooperative with the hub for facilitating sliding movement of the handle portion along the hub while the guidewire extension is at least partially inserted into the guidewire lumen. The handle portion is free to slide over the entire length of the hub and to slide off the hub in both proximal and distal directions. A guide element maintains the handle portion engaged for sliding movement along the balloon catheter. The guidewire lumen is slitted and the handle portion carries a separator for opening the slit in the region of the location of the handle portion. The guide element is separable from the handle portion and separates from the handle portion and docks at the distal end of the hub when the handle portion is slid past the hub's distal end in a proximal direction.

摘要： A dilation catheter for use in medical procedures is provided including a dilation balloon disposed on the distal end of a flexible tubular shaft. The balloon has perfusion characteristics and may be varied between a collapsed condition and an expanded condition by the introduction of fluid into the balloon. The balloon includes a compliant portion which extends radially outwardly when the balloon is in its expanded condition for engaging a body vessel wall and a non-compliant longitudinal section which traverses the length of the balloon and does not extend radially outwardly when the balloon is in its expanded condition, forming a perfusion channel.

摘要： A removable vascular filter system for blocking micro- and macro-emboli while allowing the continued perfusion of blood comprises a filter membrane positioned on a guidewire, wherein a free end of the membrane sits tightly against the guidewire when the filter membrane is in a collapsed state and wherein the filter has a means for deploying the filter membrane to assume a position substantially normal to the longitudinal axis of the guidewire. The filter membrane is comprised of a fine mesh material which has a pore size capable of blocking emboli while allowing continued blood flow, a preferred embodiment of which comprises regularly spaced, laser-formed holes, and in which the membrane has a scalloped proximal profile.

摘要： A catheter having an elongated tubular body with a distal end, a proximal end and at least one lumen extending therebetween. The body is made from three layers of extruded plastic which adhere to each other. The body has an inner and outer layer made from a polymer, and a middle layer also made from a polymer. The middle layer is more flexible and has a lower melt temperature than the inner and outer layers. The catheter further includes an integral fuseless distal tip. The distal tip is made from the middle layer and no more than one of the inner and outer layers. The distal tip is softer than portions of the body proximal thereto. In accordance with another aspect of the present invention, there is provided a method of making a fuseless soft tip tubular catheter, of the type described above. The method involves extruding the catheter so as to form the tubular body having the inner, outer and middle layers. Thereafter, at least the distal end of the catheter is heated so as to form a distal tip. The distal tip is made from the middle layer and no more than one of the inner and outer layers. The distal tip is softer than portions of said body proximal thereto.
