摘要： A catheter handle for controlling the advancement of a guide wire through a catheter is described. The catheter handle has a distal end to which is coupled a luer lock element, and a proximal end to which a control knob is coupled. The luer lock element is adaptable to allow coupling of the catheter handle to any commonly available commercial catheter. The control knob is coupled to a guide wire advancement mechanism. Movement of the control knob is translated by the advancement mechanism to advancement or braking of the guide wire.

摘要： A catheter for controlling the advancement of a guide wire includes a catheter body having a central lumen, a first side lumen and a second side lumen. A pair of opposing control wires extend the length of the catheter body through the side lumens. The catheter body includes a proximal portion coupled to a less rigid distal portion. A control handle coupled to the proximal ends of the control wires produces opposing motion of the control wires along the length of the catheter body, causing the distal portion of the catheter body to deflect relative to the proximal portion of the catheter body, thus directing the guide wire. In one embodiment, the control handle includes a guide wire advancement mechanism for controlling the advancement of the guide wire through the catheter.

摘要： Expandable laser catheters for utilizing laser energy to remove obstructions from body passages are described. The laser catheter includes a shaftway having a distal end including a flexible portion configured in a series of radial folds. Multiple optical fibers, configured to transmit laser energy, extend along the shaftway and are attached to the flexible portion. An inflatable, ring-shaped balloon is attached to the catheter within the flexible portion. In use, the catheter is inserted into a body passage such as an artery, and advanced until the distal end is adjacent to an obstruction. The balloon is inflated to expand the flexible portion and to bring the optical fibers nearer the inner wall of the body passage. Laser energy is directed by the optical fibers toward targeted regions of the obstruction. As the catheter is advanced and the process repeated, as described herein.

The guidance system is coupled to the catheter body and includes a first optic fiber, a second optic fiber, and a detecting element. The first optic fiber includes a first end and a second end, and is coupled to the catheter body so that the first optic fiber second end is adjacent the catheter second end. The second optic fiber also includes a first end and a second end, and a reference mirror is positioned adjacent the second optic fiber second end. The first optic fiber first end is communicatively coupled to the detecting element and the second optic fiber first end is communicatively coupled to the detecting element. The detecting element is configured to determine interference between a light beam propagating through the first optic fiber and a light beam propagating through the second optic fiber.

摘要： Catheters for photoablating plaque build-up in blood vessels are described. In one form, the catheter includes a catheter body having a first group of optic fibers and a second group of optic fibers. The first group of optic fibers is adjacent the second group of optic fibers, and each group of optic fibers includes at least one optic fiber having a first end and a second end. The second ends of the respective optic fibers form a substantially rounded hemispherical catheter head. A control element is coupled to the catheter body and is configured to selectively transmit energy through either the first group of optic fibers, or the second group of optic fibers, or both the first and second groups of optic fibers.

摘要： A vascular graft is held in a collapsed state on a pair of stents which take the form of flexible sheets wound around a spool. A sheath is fitted closely around the graft to hold it in its collapsed state and to retain the stents in rolls tightly wound on the spool. After the spool has been inserted into a damaged vessel and advanced to the area of vascular damage, the sheath is withdrawn. The stents then unwind and expand to press the ends of the graft against healthy parts of the vessel on opposite sides of the damaged area. An alternative embodiment of the invention includes a Y-shaped graft for application to a branched part of a vessel. In place of a sheath, control cords with slip knots are used to retain the stents in their contracted conditions while the graft is being positioned in the vessel. The control cords can be pulled to release the slip knots and permit the stents to expand in a manner to secure two branch portions of the graft in the vessel branches and a trunk portion of the graft in the main trunk of the vessel.
