    摘要： A method of making a catheter balloon or other expandable tubular medical device or component thereof, in which an assembly of heat shrink material on an outer surface of coaxially disposed first and second tubes is heated to radially shrink the heat shrink material and reduce the outer diameter of the first tube. In a presently preferred embodiment, the heat shrink material extends at least along a central section of the first tube to reduce the outer diameter of the first tube at least along the central section of the first tube. The first and second tubes form the outer and inner layers, respectively, of a multilayered balloon, which has an improved low profile outer diameter.

    摘要： A catheter balloon or other expandable tubular medical device or component, having at least a first layer with a first section and a second section longitudinally compacted by more than the first section. In a presently preferred embodiment, the second section of the first layer extends at least in part along a central portion of the length of the first layer. The longitudinal compaction of the material of the first layer preferably results in a balloon or other expandable tubular medical device or component having improved performance characteristics such as compliance and dimensional stability. One aspect of the invention is directed to a method of longitudinally compacting a porous polymeric tube incrementally along the length of the tube, to compact sections of the tube.

    摘要： A balloon for a catheter and a method of making the balloon, having a layer of a porous polymeric material with a modified outer surface and a lubricious coating bonded to the modified outer surface. In one embodiment, the modified outer surface is formed by a polymer impregnated in the porous polymeric material, and the subsequently applied lubricious coating bonds to the impregnating polymer. In another embodiment, the modified outer surface is formed by a functionality deposited on the porous polymeric material which bonds to the subsequently applied lubricious coating. The modified outer surface provides an improved strong bond between the lubricious coating and the balloon, for improved catheter performance.

    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.
