摘要： A tissue removal device including customizable tips and method of use thereof. The tissue removal device may include an outer shaft having a removable tip attached to the outer shaft and a rotatable inner shaft extending through the outer shaft and having a rotatable cutting portion extending from the inner shaft. Disc material may be cut and removed from a surgical area using an auger-like and/or suction mechanism to facilitate the transfer of removed tissue away from the surgical area.

摘要： A catheter (10) for introduction into a body vessel includes a shaft, a balloon (12) positioned at the distal end of the shaft, and at least one scoring wire (30) to score a vascular lesion. A distal end portion of the scoring wire is detachably connected to the catheter, such as by way of magnetic coupling (30a), thereby allowing for selective use of the catheter in a scoring or non-scoring configuration. The balloon expands when fluid is delivered to the balloon through an inflation lumen. This expansion pushes the scoring wire against the vascular lesion.

摘要： An occlusion clearing device for a patient has a housing with a motor(s) that generates repetitive motion, which is reciprocating, rotational or both. A clearing stem including a sheath that has a lumen, wherein aspiration is conducted through the sheath lumen. A wire is located in the sheath lumen and receives repetitive motion from the controller. The sheath terminates in a sheath end having at least one sheath opening. The wire terminates in a wire tip, which may be flat, helical, or tubular. The wire tip is positioned within the sheath end, in proximity to the sheath opening(s), and movement of the wire tip and/or sheath end relative to each other creates shearing forces that break up an adjacent occlusion.

摘要： A tissue-removing catheter generally comprises a drive shaft having opposite proximal and distal ends and configured for rotation about a longitudinal axis, and an abrasive burr operatively connected to the distal end of the drive shaft such that rotation of the drive shaft about the longitudinal axis imparts rotation to the abrasive burr. The abrasive burr includes circumferentially spaced longitudinal struts defining longitudinal slots between adjacent struts, proximal and distal hubs secured to the respective proximal and distal ends of the longitudinal struts, and an abrasive exterior surface covering an abrasive longitudinal portion of each strut extending from adjacent the proximal ends of the longitudinal struts to adjacent the distal ends of the longitudinal struts. Proximal and distal longitudinal end portions of the longitudinal struts adjacent the junctions of the longitudinal struts and the respective proximal and distal hubs are free from the abrasive exterior surface.

摘要： A method and dissecting device are disclosed for treating a stenotic vessel. The method including inserting a directional guide member of a dissecting device into a subintimal space from a blood vessel; sliding a tubular cutting member on the directional guide member through the subintimal space; and cutting a stenotic region with the tubular cutting member as the cutting member slides towards a distal end of the directional guide member.

摘要： A power tool for removing an intervertebral disc and preparing vertebral endplates is described. The power tool may include a cutting element, and the height of the cutting element may be adjustable. The cutting element may be a braided cable and may include one or more beads to enhance the effectiveness of the cable. The cutting element may have a minimum height requirement, which may not be satisfied in patients with a collapsed disc due to degenerative disc disorder. For these patients, also described are bone tamps for increasing the intervertebral distance and providing access to tissues distal to the tamp. One type of bone tamp features an inflatable balloon with an inner lumen. Another type of bone tamp includes an expanding distal end and an inner cannula. Also described is a manual expander scraper tool that is compatible with both types of bone tamp.

摘要： An assembly insertable into a lumen of a patient including a motor housing having a motor contained therein, a motor shaft extending from the motor, a first coupler positioned at the motor shaft having a first magnet positioned therein adjacent a distal end, a rotational wire, and a second coupler positioned at a proximal portion of the thrombectomy wire. The second coupler has a second magnet positioned therein adjacent a proximal end. The second coupler is engageable with the first coupler to operably connect the rotational wire to the motor shaft, the first and second magnets providing an attractive force between the first and second couplers to maintain a connection of the first and second couplers so rotation of the first coupler rotates the second coupler.
