    摘要： A balloon catheter and a method of making a balloon catheter, having a balloon with a first layer and a second layer, the first layer having at least one impregnated section impregnated with a polymeric material compatible with a polymeric material forming the catheter shaft. At least a portion of the impregnated section is fusion bonded to the shaft. In a presently preferred embodiment, the impregnated section is adjacent to a section of the first layer which is not impregnated with the compatible polymeric material. The impregnated section provides improved bonding of the balloon to the catheter shaft while minimizing the effect of the bond on catheter performance characteristics such as profile and flexibility.

    摘要： An intravascular catheter system for properly implanting a stent in a body lumen generally comprising a catheter having an elongated shaft with an inflatable balloon formed of compliant material and a stent mounted on the working length of the balloon. The balloon material is compliant within the working range of the balloon to provide substantial radial expansion. The wingless radially expansive balloon expands in a uniform manner, thereby producing uniform expansion and implantation of the stent.

    摘要： A resizable inflatable balloon, primarily for use with balloon catheters. The resizable inflatable balloon comprises a first portion and an adjacent second portion. The first portion is inflatable to a working diameter at a first pressure while the second portion does not substantially expand at the first pressure. The second portion does expand to the working diameter at a second pressure greater than the first pressure, so that subsequent inflation at the first pressure inflates the first portion and the second portion to the working diameter. The methods of resizing the inflatable members include placing the inflatable balloon in a mold and supplying inflation fluid to expand the second member to the working diameter. In practice, a catheter having the resizable inflatable balloon is guided through a patient's vasculature until the inflatable balloon is positioned in a desired region. Inflation fluid is supplied at the first pressure to inflate the first portion to the working diameter. The catheter is withdraw and the inflatable balloon is resized as described above. The catheter is reintroduced to the patient's vasculature and inflation fluid is then supplied at the first pressure to inflate both the first and second portions.

    摘要： A catheter having an multilayered shaft section with a first layer formed of a polyimide first material and a second layer formed of a second material. In a presently preferred embodiment, the polyimide material is a thermoset polyimide. However, in alternative embodiments, a thermoplastic polyimide is used. The thermoset polyimide has a very high glass transition temperature (Tg) of approximately 400° C. (as measured by differential scanning calorimetry), and excellent dimensional stability at the processing temperature of polyamides commonly used in catheter components. As a result, during formation and assembly of the catheter, production of a thin polyimide layer with controlled dimensions is facilitated. The polyimide has a high modulus and provides a thin walled yet highly pushable shaft section, while the second layer provides kink resistance. In one embodiment, the second material is selected from the group consisting of a polyamide material and a polyurethane material.

    摘要： A catheter having an elongated shaft which has a multilayered distal tip with a first layer formed of a polyimide first material and a second layer formed of a polymeric second material. In one embodiment the multilayered distal tip is a separate member, distal to the distal end of a proximal portion of the shaft. In another embodiment, the shaft has an outer tubular member, and a multilayered inner tubular member with a distal end which forms the multilayered distal tip of the shaft. In a presently preferred embodiment, the polyimide material is a thermoset polyimide. In one embodiment, the polymeric second material is a polyamide material.
