An atherectomy catheter directs particles generated by a cutting element into a collection chamber. A lumen configured to direct fluid into the tissue collection chamber.

Material removal device having improved material capture efficiency and methods of use

Medical systems and related methods are disclosed. In some embodiments, the medical systems include an inner tubular member defining an aperture and an outer tubular member at least partially surrounding the inner tubular member. The inner and outer tubular members can be arranged such that an implantable medical endoprosthesis can be disposed therebetween.

Medical systems and related method

The present invention provides an atherectomy catheter which has a cutting element that is able to cut both soft tissue and hard tissue, and methods of cutting material from a blood vessel lumen using a rotating cutting element. The cutting element has a sharp cutting edge that surrounds a cup-shaped surface and at least one surface of abrasive material. The cup-shaped surface directs the cut material into a tissue chamber. The cutting edge and the cup-shaped surface together are well suited to cut and remove relatively soft tissue from the blood vessel. The abrasive material surface in combination with the cutting element is well suited to abrade and remove hard material from the blood vessel.

Methods and devices for cutting and abrading tissue

A catheter which includes a cutting element having one or more raised elements is provided. The cutting element has a cup-shaped surface at the distal end that may be smooth and continuous except for the raised elements. The raised elements have a surface that tends to direct cut particles of material towards one or more of the axis of rotation of the cutting element, the catheter axis, or a particle collection chamber. In further aspects of the invention, a cutting element oscillates in a direction roughly parallel to the axis of rotation of the cutting element.

Device for cutting tissue

A cleaning device includes a flushing chamber having opposite proximal and distal ends, and a length extending between the proximal and distal ends. An inlet port of the cleaning device is in fluid communication with the flushing chamber and configured for fluid connection to a source of fluid. The flushing chamber is selectively openable along its length to an open position, in which the distal end portion of the medical instrument is insertable into the flushing chamber, and selectively closable along its length to a closed position, in which the distal end portion of the medical instrument is enclosed and fluidly sealed within the flushing chamber.

Cleaning device for medical instrument and method of use

A cleaning device for a medical instrument including a flushing chamber, the flushing chamber having a lumen sized and configured to accept a distal end portion of the medical instrument during a cleaning process. The flushing chamber has an inlet port and an outlet port. Proximal and distal sealing members of the flushing chamber seal about the medical instrument when the instrument is inserted into the lumen of the flushing chamber.

Medical systems and related methods are described. In some embodiments, the medical systems include an outer member defining a slot. In certain embodiments, the outer member at least partially surrounds an inner member, and the outer and inner members are configured so that an implantable medical endoprosthesis can be disposed between the outer and inner members.

Medical systems and related methods

An atherectomy catheter directs particles generated by a cutting element into a collection chamber. A paddle attached to the cutting element propels fluid distally in the tissue collection chamber.

A catheter having a tubular body and a rotatable shaft disposed within a lumen of the tubular body. A cutting element is coupled to the rotatable shaft, the cutting element having a cutting edge, the cutting element and rotatable shaft being longitudinally moveable within the tubular body between a stored position in which the cutting element is positioned distal of a side opening and a cutting position in which the cutting element is contained within the lumen of the tubular body and longitudinally aligned with the side opening. The cutting element is configured to extend through the side opening and to cut material from the wall of a vessel at a treatment site as the catheter is pulled proximally through the treatment site. The catheter may optionally have a rotating distal tip with an abrasive surface. The catheter includes a collection chamber positioned proximally of the cutting window.
