    摘要： A balloon catheter assembly includes a first tubular member with a proximal portion and a distal portion and a lumen extending between the proximal portion and the distal portion. A balloon has a proximal waist length, a distal waist length and an expandable region therebetween disposed about the distal portion. A tie layer is disposed between the proximal waist length or distal waist length and the first tubular member. The tie layer comprises a polyester polymer and a polyamide polymer.

    摘要： A stent delivery catheter comprising a catheter shaft and balloon engaged thereto. The balloon being inflatable from a first inflation state to a first expanded state as well as to a second expanded state. The balloon having a stent mounting region for retaining and delivery of a stent therefrom, and at least one adjacent region. The stent mounting region having a first diameter and the at least one adjacent region having a second diameter. In the first inflation state the first diameter being less than the second diameter. In the first expanded state the first diameter being no greater than the second diameter. In the second expanded state the first diameter being greater than the second diameter. The stent being retained on the stent mounting region by engagement of the at least one adjacent portion and at least one retractable stent retaining sleeve.

    摘要： A medical balloon composed of a micro-composite material which provides for radial expansion of a balloon to a predetermined extent, but which has minimal longitudinal growth during balloon inflation. The micro-composite material includes a fibril component, a matrix component, and optionally, a compatibilizer. The fibril component may preferably be liquid crystal polymer fibers randomly scattered through out the balloon material. The liquid crystal polymers are created by extrusion at high speed. An alternative fibril component may be a PET fibers which are uniformly spaced about the balloon material and extend through out the length of the balloon material tube.

    摘要： A medical tubing is disclosed which includes a first material extending between proximal and distal ends of the tubing and which defines a lumen of the tubing. The tubing also includes a second material extending between at least portion of the distance between the proximal and distal ends of the tubing and that is embedded in the first material. The second material is fractured. The first material is flexible and the second material is relatively rigid and brittle and the two materials combined to provide a medical tubing that exhibits strain softening behavior.
