Abstract: Briefly summarized, embodiments disclosed herein are directed to apparatus and methods for removing an occlusion from an indwelling catheter. The system can include a pressurized fluid conduit for delivering pressurized fluid to an occlusion site, and ablating the occlusion. A negative pressure source in fluid communication with the catheter lumen can then aspirate the occlusion. The positive pressure source can provide a pulsed pressurized fluid to facilitate ablation. The system can also include tip tracking and tip location systems to ensure the pressurized fluid conduit does not extend beyond the catheter lumen, causing damage to the vasculature. The system can further include an ultrasound transducer, coupled with one of the catheter and the pressurized fluid conduit to provide ultrasonic wave energy to the occlusion to further facilitate ablation thereof.

Abstract: A system and method of integrating electromagnetic microsensors into interventional endovascular devices such as guidewires for tracking guidewires within vessels of a body with the use of a surgical navigation system.

Abstract: A trackable guidewire is presented. The guidewire includes a plurality of wires arranged in a predetermined pattern to form a body of the guidewire, where the plurality of wires is configured to simultaneously provide electrical conductivity of signals and mechanical strength. A guidewire assembly is also presented, where the guidewire assembly includes a guidewire, where the guidewire includes a plurality of wires arranged in a predetermined pattern to form a body of the guidewire, and the plurality of wires is configured to simultaneously provide electrical conductivity of signals and mechanical strength, and one or more sensing devices, where the one or more sensing devices are operatively coupled to the guidewire. Methods of making the guidewire and the guidewire assembly are also contemplated in conjunction with the present technique.

Abstract: A tissue tracking assembly and method is disclosed herewith. The tissue tracking assembly comprises: a flexible probe with a proximal end and distal end, the proximal end incorporates an electric connector and the distal end incorporates at least one trackable sensor. A delivery system is provided in association with the flexible probe to accurately embed the flexible probe within a tissue. The delivery system is configured to be attached to the flexible probe during insertion of probe within the tissue and detaches from the flexible probe after embedding the probe within the tissue.
