Coordinated control of the insertion motion of the cannulated and flexible needles, and rotation of the combined cannulated/flexible needle assembly enables access to be obtained to a volume of a region of the brain having lateral dimensions substantially larger than the width of the cannulated needle.

  • Patent number: 10531890
    Abstract: A device for introduction into a body vessel includes a shaft, a balloon positioned at the distal end of the shaft, a guidewire disposed longitudinally within the shaft to receive a guidewire during use, a balloon disposed at the distal end of the shaft, and longitudinal scoring wires to score a vascular lesion attached to the distal end of the shaft. The scoring wires are disposed over the balloon and disposed within the shaft. The proximal ends are welded or otherwise affixed to a spring mounted in the handle. The balloon expands when fluid is delivered to the balloon through the inflation lumen. This expansion pushes the scoring wires against the vascular lesion. The scoring wires attach to a source of vibrations. The scoring wires are made of a helical coil.

  • Patent number: 10532187
    Abstract: A steerable catheter is disclosed, having an elongated, tubular catheter body with at least one deflection member slidably disposed within a lumen, secured at a distal end to a tip section and terminating in an interconnect at a proximal end and a handle releasably attached to the proximal end of the catheter body. The handle has at least one sliding member coupled to an actuator, such that manipulation of the actuator causes relative longitudinal movement with respect to the handle, wherein the interconnect and the sliding member engage when the handle is attached to the catheter body so that the relative longitudinal movement of the sliding member is transmitted to the deflection member and wherein the interconnect and the sliding member disengage when the handle is released from the catheter body.

  • Patent number: 10492806
    Abstract: In a medical guide wire having a connecting structure formed by three members: a tubular connector; a first core; and a second core, when a torsional rigidity of one member is lower than the torsional rigidity of the materials of both end portions, for example, the twist is unevenly generated between the members and the rotation transmission performance to the distal end side is significantly reduced. In such a case, there is a technical problem for improving the rotation transmission performance to the distal end side. In the connecting structure formed by three members, as a result of focusing on the torsional rigidity of the three members and considering the torsional rigidity ratios between the members, the technical problem for improving the rotation transmission performance to the distal end side can be solved when the torsional rigidity ratios satisfy a predetermined relation.

  • Patent number: 10492936
    Abstract: Tortuosity of vessels at or leading to the site of minimally invasive procedures is a problem for conducting such procedures as they increase the difficulty to guide the procedural catheters through tortuous vessels. Methods and apparatus for stabilization of the sheaths and catheters during access, procedures, and withdrawal in these tortuous vessels are disclosed. The apparatus and method for improving access include application of a pull component to the stabilized procedural catheter using a stabilization catheter/wire in addition to a push component from the percutaneous access to make the access easier while enabling use of more flexible catheters and softer wires. These methods and devices address the problems of trauma to the vessels during access, procedure and removal of catheters and wires, improve pushability of softer catheters and wires, and also substantially reduce substantially the procedure time.
