Abstract: An interventional catheter assembly has an operating head [400] and catheter system [300] that are inserted and navigated within a patient's body while an operator controls the system externally of the operating head. Fluidic communication is provided between the operating head and the external system controls, and rotation is provided to the operating head by means of an external drive system. Numerous system controls are provided, along with various operating systems, sealing assemblies, actuators, torque transfer systems, and the like are provided. Some systems and controls are provided in a control pod [200] and some controls, as well as displays, are provided in a console unit [100]. Control pod [200], catheter system [300] and operating head [400] may be provided as a sterile, single use interventional catheter system, while the console unit [100] may be provided as a multiple use device that communicates with the sterile, single use interventional catheter system during operation.

Abstract: A torque transmitting system supports rotational and lateral movement of a drive shaft. The system includes translating inner and outer tubes which have aligned canals for placement of a ball bearing and a pinion shaft to couple the tubes to a drive system. Rotational torque is transferred from the pinion shaft, to the outer tube and, through the ball positioned in the aligned canals, to the inner tube and then to the drive shaft. Furthermore, the ball engaged in the canals defines a range of motion in which the inner tube is slidable with respect to the outer tube, along the tubes' longitudinal axis, to permit advancement of an attached drive shaft.

Abstract: Intralumenal material removal systems are provided using an advanceable and rotatable cutter assembly designed for differential cutting. The intralumenal material removal system includes a cutter assembly positionable in the body cavity of a mammalian subject. One embodiment of the cutter assembly comprises a cutter with blades that are designed and arranged to form an acute blade angle of attack with the matter-to-be-removed. The cutter assembly is axially advanceable by translating the drive shaft and rotatable by rotating the drive shaft. The occlusive material is scraped by the cutter assembly and may be aspirated to remove the material from the body cavity. The cutter assembly may provide aspiration ports positioned between facing surfaces of the blades.

Abstract: A slip seal adapter is for insertion within a connector of movable catheter components. The adapter includes a rigid tube and a thermally shrinkable wrap extending from the tube. A lumen runs through the adapter to permit the catheter to pass through the connector and through the adapter lumen, whereby the shrinkable wrap sealably surrounds a portion of the catheter. The shrinkable wrap comprises a lubricious material that permits the enclosed catheter to move in a lateral and/or rotational direction and yet maintains the close contact with the catheter.
