  • Publication number: 20120209323
    Abstract: A sealant is provided for sealing a puncture through tissue that includes an elongate first section including a proximal end, a distal end, and a cross-section sized for delivery into a puncture through tissue, and a second section fused to and extending from the distal end of the first section. The first section may be formed from a freeze-dried hydrogel that expands when exposed to physiological fluid within a puncture. The second section may be formed from a solid mass of non-freeze-dried, non-crosslinked hydrogel precursors, the precursors remaining in an unreactive state until exposed to an aqueous physiological, whereupon the precursors undergo in-situ crosslinking with one another to provide an adhesive layer bonded to the first section. Apparatus and methods for delivering the sealant into a puncture through tissue are also provided.

  • Patent number: 7981244
    Abstract: 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.

  • Patent number: 7951413
    Abstract: 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.

  • Patent number: 7892469
    Abstract: 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. Another embodiment is directed to a balloon catheter, having a semi-compliant balloon or a noncompliant balloon formed at least in part of a block copolymer.
