  • Patent number: 6077273
    Abstract: An angioplasty and stent delivery system to facilitate introduction and placement of a stent, including a catheter having an expandable distal portion constructed and arranged for expanding the outer diameter of the catheter from a contracted state to an expanded state: a stent positioned around the distal portion of the catheter having a contracted condition and being expandable to an expanded condition, and being sized in the contracted condition to closely surround the catheter in the contracted state, the expandable distal portion of the catheter including a balloon within which or over which there is included on a catheter shaft at least one axially movable or enlargeable body of a diameter larger than the catheter shaft to which the stent and balloon are fitted, as by crimping, for holding the stent in place until it is released therefrom by expansion of the balloon.

  • Patent number: 6071273
    Abstract: A fixed wire balloon catheter for use in angioplasty includes an elongated flexible thin walled metal tube which carries an inflatable balloon at its distal end. A metal core member of smaller outer diameter than the metal tube is attached to the distal end of the tube to provide support for and guiding of the balloon section. The proximal end of the balloon is connected either to the distal end of the metal tube or to an intermediate waist tube, with the core extending distally from the metal tube through the balloon. The distal end of the balloon is secured to the core. A vent arrangement is provided to purge the catheter of gases prior to use.

  • Patent number: 5968069
    Abstract: A system/assembly for delivery and deployment of an inflation expandable stent within a vessel, comprising a catheter having proximal and distal ends; a stent, inflation expandable from a delivery diameter to a deployment diameter, such that the delivery diameter is reduced from the deployment diameter for conforming the stent to the catheter, such that the stent, in its delivery diameter, is coaxially mounted on the catheter near the catheter distal end; an expandable inflation means coaxially mounted on the catheter axially within the stent, for expansion of the stent from the delivery diameter to the deployment diameter upon application of fluid deployment pressure to the inflation means; and a securement component coaxially mounted on the catheter, axially within the expandable inflation means, the securement component designed and adapted to provide a securement pressure to the stent in the delivery diameter to maintain the stent in position on the catheter during delivery to the deployment site.

  • Patent number: 5702364
    Abstract: A fixed wire balloon catheter for use in angioplasty includes an elongated flexible thin walled metal tube which carries an inflatable balloon at its distal end. A metal core member of smaller outer diameter meter than the metal tube is attached to the distal end of the tube to provide support for and guiding of the balloon section. The proximal end of the balloon is connected either to the distal end of the metal tube or to an intermediate waist tube, with the core extending distally from the metal tube through the balloon. The distal end of the balloon is secured to the core. A vent arrangement is provided to purge the catheter of gases prior to use.

  • Patent number: 5567203
    Abstract: An intravascular balloon catheter is disclosed which includes a proximal hypotube shaft segment, a distal polymer shaft segment, a distally-mounted inflatable balloon segment, and a hollow tubular member having a proximal end connected to the distal end of the hypotube shaft segment such that the lumen of the hollow tubular member is in communication with the exterior of the balloon catheter and the distal end of the hollow tubular member is connected to the distal end of the balloon.

  • Patent number: 5256145
    Abstract: A balloon catheter system having a guiding wire, a balloon, and a spring tip joined to a distal end of the guiding wire. A strain relief member covers a portion of the guiding wire between a distal end of the balloon and a proximal end of the spring tip. The strain relief member is defined by a portion of the balloon. Alternatively, the strain relief member comprises a separate tubular member.

  • Patent number: 5137517
    Abstract: A device for gripping a medical shaft such as a guide wire or catheter tube has two operative components: a body member with a longitudinal slot for receiving the shaft and an insert member slidably received in the slot of the body member. The body member and insert member have opposed, generally parallel shaft engagement surfaces which extend longitudinally along the shaft on each side thereof. Moving the insert member longitudinally relative to the body member activates a slide arrangement which moves the opposed surfaces laterally toward one another to grip the shaft therebetween while remaining generally parallel.
