Abstract: 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.

Abstract: Catheters and methods for removing material from (or “debulking”) a body lumen while imaging the region comprised of the material are provided. The catheters can be used in body lumens, including but not limited to intravascular lumens such as coronary or peripheral arteries. The catheters include housings or other structures to mount or protect an imaging transducer. Generally, debulking catheters include a proximal portion, a distal portion having an opening, a cutting element which may be exposed through the opening to contact material in a body lumen and an imaging transducer with associated circuitry and display. The catheter debulks a body lumen when it is moved while the cutting element is in contact with the material in the lumen and the region comprised of the material is imaged before, after, or during catheter movement.

Abstract: The present invention provides an improved atherectomy catheter having means for directing particles generated by a cutting element into a collection chamber. Methods of directing the cut material from a blood vessel lumen into a collection chamber are also provided.

Abstract: An improved atherectomy catheter includes a part for propelling fluid distally in a tissue collection chamber. The part includes a drive shaft having a proximal end and a distal portion, and a propeller attached to the distal portion of the drive shaft.

Abstract: A bracket is provided. In an embodiment, the bracket comprises a first seat and a second seat. The first seat is sized to retain a first fluid implement. The second seat is sized to retain a second fluid implement from the bracket. The second seat includes a top opening, a side opening and a front concave portion. The second seat is configured to prevent inadvertent removal of the second fluid implement from the bracket. A fluid delivery apparatus including the bracket, as well as a method for delivering fluid, such as medical fluids including nutritional fluids, and industrial fluids through the delivery apparatus is also provided.
