  • Patent number: 10675443
    Abstract: The present disclosure provides a medical device comprising an actuator restraining assembly configured to assist in restraining a catheter shaft in a deflected configuration. The actuator restraining assembly may include a brake element, a release element, a connecting sheath, and a connecting rod disposed in a catheter handle, wherein the connecting sheath and connecting rod are attached to an actuator mechanism, and wherein the at brake element is attached to the connecting sheath and the release element is attached to the connecting rod. The brake element is sized and configured to contact an inner wall of the handle to thereby provide resistance to movement of actuator mechanism in a proximal direction with respect to the handle. In one embodiment, the actuator restraining assembly is configured to allow for temporary, i.e., reversible, restraining of the catheter shaft in the deflected configuration.

    Abstract: A delivery apparatus includes a steerable shaft having a proximal portion, a distal portion, and a pull-wire conduit that extends through the proximal and distal portions. A pull wire extends through the conduit and has a distal portion that is fixed to the shaft. An adjustment mechanism is connected to the proximal end portion of the pull wire and configured to increase and decrease tension in the pull wire to adjust the curvature of the shaft. The distal portion of the shaft has a steerable portion including one or more layers. A compression-resistance portion is incorporated into a layer of the steerable portion, and extends angularly along a portion of a cross-section of the layer. The layer of the steerable portion into which the compression-resistance portion is incorporated has a first hardness, and the compression-resistance portion has a second hardness that is greater than the first hardness.

  • Patent number: 10569053
    Abstract: An improved bi-directional steerable catheter is provided. The catheter generally comprises a catheter body, tip section and control handle. The catheter further comprises first and second puller wires extending from the control handle, through the catheter body and into the tip section. The control handle has deflection means for each puller wire that include a gear, and a carrier to which the proximal end of a puller wire is anchored. The gear is rotatably coupled to a lever controlled by an operator and the gear engages the carrier such that rotation of the gear by the lever results in longitudinal movement of the carrier, which results in deflection of the tip section.

  • Patent number: 10463439
    Abstract: A steerable catheter system may include a flexible elongate catheter body, a drive mechanism at the proximal end of the catheter body, and at least one group of pullwires extending along a length of the catheter body. The catheter body may include a distal articulating section and a proximal non-articulating section. Each group of pullwires includes at least two pullwires, and each of the pullwires is anchored at a first end to the distal end of the catheter body and at a second end to the drive mechanism. The pullwires of each group are positioned close to one another in the catheter wall to concentrate the forces and cause deflection along the articulating section of the catheter body and diverge away from one another to reach a more separated distribution around a circumference of the catheter body to distribute the forces and prevent deflection along the non-articulating section.

  • Patent number: 10456565
    Abstract: A drainage catheter system includes an elongate tube with proximal and distal ends and a filament extending the tube that is adjustable to create a closed loop at the distal end of the tube when the filament is retracted relative to the tube. The filament is coupled to the tube such that the filament and tube are prevented from being separated in the event that the tube and filament are cut at the proximal end at the conclusion of a drainage procedure. The filament can be attached to the tube near the distal end. The filament can be attached to the tube along its length. The catheter system can also include a retraction mechanism having a first fixed position and second fixed position, where the second fixed position retracts the filament proximally relative to the first fixed position by actuating a plunger.

  • Patent number: 10456161
    Abstract: A tissue removing catheter includes an apposition mechanism that selectively imparts an axially compressive load on the catheter body to bend the catheter and urge a tissue-removing element toward a blood vessel wall. The apposition mechanism can include one or more adjustment lines and an adjustment mechanism for selectively tensioning one of the adjustment lines to impart the compressive load on the catheter body. Two adjustment lines can have diametrically opposed positions and be wound onto a spool of the adjustment mechanism in opposite directions so that rotation of the spool simultaneously shortens one adjustment line and lengthens the other. The catheter body can have a more flexible bending segment adjacent the tissue-removing element to promote bending near the tissue-removing element operative to urge the tissue-removing element in apposition with the blood vessel.
