An intravascular catheter device includes an expandable portion secured to a flexible catheter tube and configured for controllable movement between a first position where at least a portion of each of a plurality of struts is moved outward so as to extend beyond an outer surface of a sheath and a second position where the struts are compressed. A limiter for restricting expansion of the expandable portion is interposed between the expandable portion and a tip member located distal to the expandable portion. An incising element associated with one of the struts is configured to incise tissue located within a blood vessel when the expandable portion is placed in the first position and retracted axially along the blood vessel.

Intravascular catheter having an expandable incising portion

An intravascular device for providing feedback to an operator during use and methods of providing the same as disclosed. A catheter tube extends from a handle assembly. An expandable portion is connected to the catheter tube and is selectively movable between a first position and an expanded position. A feedback device provided at the expandable portion provides the operator with the feedback.

Intravascular device having feedback elements

An intravascular catheter device includes an expandable portion secured to a flexible catheter tube. The expandable portion is slidable relative to a sheath to selectively expose a plurality of struts for outward bowing movement and compression within said sheath. An incising element associated with one of the struts is configured to incise atherosclerotic material when the intravascular catheter device is placed within a blood vessel, the struts are exposed for outward bowing movement, and the expandable portion is retracted along the blood vessel.

An atherectomy catheter having an inner shaft which rotates a distal rotary tissue borer with a helical cutting surface which enables the catheter to out it and cross a CTO. Additionally, the atherectomy catheter has a distal cutting element rotated by an outer drive shaft configured to cut material from the wall of a vessel at a treatment site as the catheter is pushed distally through the treatment site. The atherectomy catheter includes a collection chamber positioned proximally of the cutting element and rotary tissue borer. The atherectomy catheter may include means to direct material cut from the treatment site into the collection chamber, means to break down larger portions of material that may block or clog the collection chamber and means of transporting the material collected from the treatment site to a proximal opening in the atherectomy catheter.

Material removal device and method of use

Drive shafts having helical blades and methods of making are disclosed. In one method a helical auger blade is formed by twisting or sculpting a heated polymer tube which has been placed over a cylindrical drive shaft. In another method a drive shaft is placed within a helical winding and heat is applied to melt polymer which has been coated over one or both of the drive shaft and helical winding.

Catheter with helical drive shaft and methods of manufacture

An atherectomy catheter having an inner drive shaft which rotates a distal rotary tissue borer with a helical cutting surface which enables the catheter to cut through and cross a CTO. Additionally, the atherectomy catheter has a distal cutting element rotated by an outer drive shaft configured to cut material from the wall of a vessel at a treatment site as the catheter is pushed distally through the treatment site. The atherectomy catheter includes a collection chamber positioned proximally of the cutting element and rotary tissue borer. The atherectomy catheter directs material cut from the treatment site into the collection chamber, breaks down larger portions of material that may block or clog the collection chamber and transports the material collected from the treatment site to a proximal opening in the atherectomy catheter.

A multi-composite disc prosthesis is adapted to be implanted within the annulus of an evacuated disc nucleus space in a human spine. The disc prosthesis has a generally solid unitary body with a size and a shape adapted to be positioned within the annulus of the evacuated disc nucleus space. The body has an outer portion comprised of a first biomaterial and an inner portion comprised of a second biomaterial. The second biomaterial has a compressive modulus that is harder than a compressive modulus of the first biomaterial and the first and second biomaterials are chemically or physically bonded to form a multi-composite material that forms the solid body.
