Abstract: This invention relates to a balloon dilatation catheter and its use in delivering a balloon expandable stent. More particularly, the catheter comprises a first, inflation lumen extending therethrough and having distal and proximal ends, the distal end of the first lumen opening into and being in fluid communication with the interior of an inflatable dilatation balloon having distal and proximal ends, and a second lumen extending coextensively with and exterior to the dilatation balloon.
Abstract: A magnetic device for use with a medical catheter and a guidewire incorporates a magnet adapted to attract a portion of the guidewire and thereby impose a magnetic force tending to inhibit longitudinal motion of the guidewire.
Abstract: This invention relates to a balloon dilatation catheter. The balloon dilatation catheter comprises a first, inflation lumen extending therethrough and having distal and proximal ends, the distal end of the first lumen opening into and being in fluid communication with the interior of an inflatable dilatation balloon having distal and proximal ends, and a second lumen extending coextensively with and exterior to the dilatation balloon.
Abstract: The present invention represents improved catheters and guidewires for use in medical applications designed to transverse tortuous anatomical pathways and/or cross lesions/stenoses within body cavities and/or blood vessels wherein the catheters and guidewires are provided with an integral vibration means which enhances the ability of said catheters and guidewires to effectively cross the said lesions or stenoses.
Abstract: This invention relates to a balloon dilatation catheter which comprises a first, inflation lumen extending therethrough and having distal and proximal ends, the distal end of the first lumen opening into and being in fluid communication with the interior of an inflatable dilatation balloon having distal and proximal ends, and a second lumen extending coextensively with the first lumen and having proximal and distal portions. The distal end of the second lumen is open, the distal portion of the second lumen has an opening proximal to the proximal end of the dilatation balloon, the portion of the second lumen distal to the opening is enlarged as compared to the proximal portion to facilitate receiving a guidewire in a sliding fit, and the portion of the second lumen proximal to the opening contains a pushing wire.
Abstract: Packaging for a medical catheter has a mounting card on which the catheter is placed and a cover sheet for covering the catheter to form a pouch or envelope. Discrete portions of the cover sheet are affixed to the mounting card on opposing sides of the catheter body, to restrict movement of the catheter from a desired shape.
