Catheter

A catheter can restore the patency of a body lumen, for example, by removing tissue from a body lumen (e.g., a blood vessel). The catheter can be a rotational catheter having a rotatable drive shaft and a tissue-removing element secured to the drive shaft to be driven in rotation by the drive shaft. The catheter can have an abrasive burr configured to abrade tissue in a body lumen. The catheter can have an expandable tissue-removing element. The catheter can include a balloon and an inflation conduit. The catheter can also be configured to move over a guidewire through a body lumen. In one embodiment, the catheter comprises an over-the-wire, balloon-expandable, rotational, and abrasive tissue-removing catheter.

ATHERECTOMY DEVICE

An atherectomy device for removing deposits such as plaque from an interior of a vessel including an outer member and a rotatable shaft positioned for rotational movement within the outer member and fixed axially within the outer member. A tip is mounted to the distal region of the rotatable shaft and is positioned distally of the distal end of the outer member to create a gap between the proximal end of the rotatable tip and the distalmost edge of the outer member. The rotatable tip has a longitudinal axis mounted to the rotatable shaft for rotation about its longitudinal axis upon rotation of the shaft, the shaft including a guidewire lumen for receiving a guidewire to enable over the wire insertion of the device.

Sacroiliac fusion system

Methods and apparatuses for performing an orthopedic procedure in the sacroiliac region are disclosed. In one form, an aperture is formed that at least partially extends through at least one of an ilium and a sacrum. An undercutting system is inserted into the aperture. The undercutting system may include an insertion apparatus, a probe assembly, and a cutting assembly. The probe assembly is moved with respect to the insertion apparatus from a retracted position to an extended position. The probe assembly is manipulated within a joint between the ilium and the sacrum while the probe assembly is in the extended position. The cutting assembly is moved with respect to the insertion apparatus from a retracted position to an extended position. The cutting assembly is manipulated within the joint between the ilium and the sacrum while the cutting assembly is in the extended position to form a fusion region.

Devices and methods for intrabody surgery
11737778 · 2023-08-29 ·

A device for intrabody surgery comprises a cutting arrangement rotatable by a hollow driveshaft, which is formed by a hollow front cutting region and a rear region. The front region includes multiple longitudinal drilling sections interconnected by transversely oriented cutting blade sections. The drilling sections are positioned at an angle to each other defining in combination with the cutting blades a conically shaped grid formation having a hollow internal cavity. The grid formation defines a plurality of ports between the drilling sections and the blades. A low-pressure zone is formed within the hollow internal cavity, wherein cut occlusion materials are aspired by the low-pressure zone through the plurality of ports into the hollow internal cavity for further evacuation from the cutting arrangement.

ATHERECTOMY DEVICES AND METHODS

Rotational atherectomy devices and systems can remove or reduce stenotic lesions in blood vessels by rotating one or more abrasive elements within the vessel. The abrasive elements are attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly that includes a driver for rotating the drive shaft. In particular implementations, the handle assembly encapsulates an electric motor assembly, a pump assembly, and a controller assembly.

Method and apparatus for discontinuous dermabrasion

Exemplary embodiments of method and apparatus are provided for resurfacing of skin that includes formation of a plurality of small holes, e.g., having widths less than about 1 mm or 0.5 mm. For example, such small holes can be produced using a mechanical apparatus that includes one or more abrading elements provided at the end of one or more rotating shafts, thus avoiding generation of thermal damage as occurs with conventional laser resurfacing procedures and devices. The holes thus formed can be well-tolerated by the skin, and may exhibit shorter healing times and less swelling than conventional resurfacing procedures. The fractional surface coverage of the holes can be between about 0.1 and 0.7, or between about 0.2 and 0.5. The method and apparatus can produce cosmetic improvements in the skin appearance by eliciting a healing response.
