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

The disclosure includes a vein ablation system, comprising a catheter having an elongated body. In some embodiments, the vein ablation system comprises an ablation device at a distal portion of the elongated body. According to some embodiments, the vein ablation system comprises a control device at a proximal portion of the elongated body. The control device may comprise an input mechanism configured to simultaneously control at least two of a longitudinal translation of the ablation device through a target vessel, a rotation of the ablation device about a central longitudinal axis, and an infusion of a chemical agent into the target vessel.

Vascular ablation

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.

The disclosure includes a controller and a sheath having an open proximal sheath end coupled to the controller, an open distal sheath end configured for insertion into a vascular system of a patient, and a working lumen extending through the sheath. The system may include a wire extending from the controller through the working lumen, the wire having a distal wire end configured to mechanically treat a vessel wall of a treatment segment, a length of the distal wire end defining a length of the treatment segment. The working lumen may be configured to slidably receive the wire and allow for a passage of a fluid about the wire therethrough to chemically treat the treatment segment. When the system receives a first input the distal wire end may mechanically treat the vessel wall. When the system receives a second input and/or a third input, the system may deliver the fluid.
