摘要： The present invention is a method of manufacturing a flexible tubular body for catheter, sheath or similar medical device. The method comprises pre-extruding an inner layer of the body from a thermoplastic polymer and then pulling the inner layer over a mandrel and tightening the layer down. If wire lumens were not integrally formed in the inner layer when pre-extruded, then two polymer spaghetti tubes, each with wire lumens, are laid 180 degrees apart axially along the outer surface of the inner layer. Deflection wires are then fed into the wire lumens. A cylindrical wire braid is woven or pulled over the inner layer (and the spaghetti tubes, as the case may be) and tightened down. The aforementioned components are then encased in an outer polymer layer. A heat-shrinkable tube is then placed over the outer layer. A pressurized fluid is injected into each wire lumen to maintain the internal diameter of each wire lumen at a diameter that is greater than the diameter of the deflection wire received in each wire lumen. Heat is then applied to the body and heat-shrinkable tube to cause the layers to laminate together. Once the newly laminated body has sufficiently cooled, the heat-shrinkable tube is removed from the body.

摘要： The present invention is a handle for controlling the deflection of a distal end of a catheter body. The catheter body includes first and second deflection wires that extend through the catheter body from the distal end of the catheter body. The handle comprises a slide base, an adjustment knob, a first slide and a second slide. The slide base includes a first end, a second end, and a slide compartment longitudinally extending through at least a portion of the slide base. The adjustment knob is rotateably connected to the first end of the slide base and includes a hole extending through the knob, wherein at least a portion of an inner diameter of the hole includes an internal right thread and an internal left thread. The first slide is located in the slide compartment, is adapted to be coupled to the first deflection wire, and includes an external right thread. The second slide is located in the slide compartment, is adapted to be coupled to the second deflection wire, and includes an external left thread. The internal threads of the knob engage the threads of the slides. Consequently, in operation, rotation of the adjustment knob causes the slides to displace in opposite directions within the slide compartment and the distal end of the catheter body to deflect accordingly.

摘要： The present invention is a catheter actuation handle 14 for deflecting a distal end 18 of a tubular catheter body 12, the handle including an auto-locking mechanism, 54. The handle comprises upper and lower grip portions 24a, 24b, an actuator 20, and an auto-locking mechanism, 54. The auto-locking mechanism 54 is adapted to hold a deflected distal end 18 of the catheter 10 in place without input from the operator. When the distal end 18 of the catheter 10 is deflected from its zero position, it typically will seek a return to its zero position, and as a result exerts a force on the actuator 20. The auto-locking mechanism 54 acts by providing a second force that resists this force from the distal end 18 and holds the distal end 18 in place. As a result, the operator does not need to maintain contact with the buttons 22a, 22b to maintain the distal end 18 in a set position once placed there by actuating the actuator 20.

摘要： A system for connecting a hemostasis valve to a splittable sheath includes an interface formed between a ledge on the proximal end of a cannula portion of the hemostasis valve and an engagement structure aligned with the handles of the splittable sheath. Pulling the handles to split the sheath likewise disengages the ledge from the engagement structure. A snap ring on the cannula portion engages a snap ring in the lumen of a sheath hub formed on the proximal end of the splittable sheath. An O-ring between the cannula portion and the sheath hub provides a fluid-tight seal.

摘要： A splittable cannula includes a radiopaque marker placed at or near the distal end of the cannula. The radiopaque marker may be a unitary piece, or may consist of several portions. The cannula may include a sheath or catheter body with a grooved score line running along a portion of the sheath body and a radiopaque marker located at a distal end of the body and abutting the body. The radiopaque marker may be located within the lumen of the sheath, may be embedded in the sheath wall, or may be affixed to the external sheath wall. The radiopaque marker may be scored, notched, grooved, or contain apertures longitudinally. The notches, grooves, apertures, and/or score lines in both the sheath or catheter body and the radiopaque marker serve to provide a weakened tear path. An electrode lead may be coupled with the radiopaque marker.
