A debulking catheter comprising a debulking assembly for debulking a body lumen. The catheters of the present invention can include a flexible proximal portion coupled to a rigid distal portion. A tissue debulking assembly can be disposed within the rigid portion to debulk the body lumen. In exemplary embodiments, the rigid portion is rotatably coupled to the flexible portion such that rotation or deflection of the rigid portion, relative to the flexible portion, can expose the tissue debulking assembly through a window in the catheter to debulk the body lumen.

Devices, kits and methods described herein may be for wound healing, including the treatment, amelioration, or prevention of scars and/or keloids by applying and/or maintaining a predetermined strain in an elastic skin treatment device that is then affixed to the skin surface using skin adhesives to transfer a generally planar force from the bandage to the skin surface. Applicators are used to apply and/or maintain the strains, and some of the applicators are further configured to provide at least some mechanical advantage to the user when exerting loads onto the skin treatment device.

A catheter for performing a procedure at a treatment site in the lumen of a blood vessel. The catheter includes an elongate tubular shaft having a proximal bend, a distal bend and a hinge element. A distal portion of the shaft includes a window extending through the sidewall of the shaft between the hinge element and the distal end of the elongate tubular shaft. A working element is disposed within the lumen of the elongate tubular shaft and is configured for performing the procedure through the window at the treatment site. The bends and hinge element are configured to urge the window against a wall of the vessel at the treatment site.

Catheters, kits, and methods are provided for removing material from a body lumen. The catheters and methods may be used in a variety of body lumens, including but not limited to coronary and other arteries. In general, the catheter has a cutting element that cuts material while the material is engaged by a material capture device on the catheter body. Preferably, the material capture device tensions the material during cutting, which reduces the amount of cutting force required. The material capture device typically follows a path that draws material into the catheter body. Preferably, but not necessarily, the material capture device may be arranged on the catheter body to advance along a path outwardly from the catheter body into the material and then inwardly towards the catheter body to tension the material. The cutting element on the catheter body moves between a first position and a second position to cut the material while in tension.

A debulking catheter comprising a tissue debulking assembly for removing material from a body lumen. Catheters of the present invention generally include a catheter body having proximal and distal portions and a tissue debulking assembly disposed at least partially within the distal portion. The tissue debulking assembly is radially movable to expose at least a portion of the assembly through a window on the catheter body to contact material in the body lumen. The catheter may then be moved to allow the tissue debulking assembly to remove all or a portion of the material. In exemplary embodiments, the distal portion of the catheter body is rotatably coupled to the proximal portion such that rotation or deflection of the distal portion, relative to the proximal portion, urges the window against material in the body lumen, exposes the tissue debulking assembly through the window, or both. In some embodiments, the flexible proximal portion includes a rigid distal portion to enhance positioning of the debulking assembly within the body lumen.

A device for reentering a true lumen from a subintimal location includes a rotating cutting element and energy emitting element. Energy is emitted to determine the location of the true lumen and the cutting element is exposed to cut an access path to the true lumen. The cutting element may be gradually exposed and the distal portion may be bent or articulated to move the cutting element toward the material to be cut.
