A first tubular body having a first longitudinal axis extending centrally through the tubular body includes at least one delivery port extending through a wall of the first tubular body. A second tubular body having a second longitudinal axis extends through the second tubular body, the first and second longitudinal axes being displaced from each other such that an asymmetrical longitudinally extending gap is formed between an outer surface of the second tubular body and an interior surface of the first tubular body. A temperature sensor forming a thermocouple extending longitudinally within the gap between the first tubular body and the second tubular body. An inner core is positioned within the second tubular body. The inner core includes least one ultrasound element.

An interventional catheter assembly has an operating head [] and catheter system [] 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 [] and some controls, as well as displays, are provided in a console unit []. Control pod [], catheter system [] and operating head [] may be provided as a sterile, single use interventional catheter system, while the console unit [] may be provided as a multiple use device that communicates with the sterile, single use interventional catheter system during operation.

Interventional catheter assemblies and control systems

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.

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 includes 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.
