  • Patent number: 10357305
    Abstract: A technique allows for an electrical connection between a thermal abrasion heating catheter and the energy delivery console that utilizes serial communication. Accordingly, the serial communication allows data such as measured temperature, start/stop status, intended treatment area, device identification, device calibration parameters and/or use history to be conveyed along the same wires that deliver power to a heating element. For example, data can be conveyed along a two wire connection and provided at a frequency that is filtered out so that it is not delivered to a heating feature. In this example, one wire provides power to the heating element, one wire provided communication from the energy delivery console, and a third wire provides a common ground which the heating catheter uses to communicate with the energy delivery console.

  • Publication number: 20070179575
    Abstract: A working end of a catheter includes at least one therapeutic element, such as a resistive heating element, usable to deliver energy for ligating, or reducing the diameter of, a hollow anatomical structure. In certain examples, the catheter includes a lumen to accommodate a guide wire or to allow fluid delivery. In certain embodiments, a balloon is inflated to place resistive element(s) into apposition with a hollow anatomical structure and to occlude the structure. Indexing devices and methods are also disclosed for successively treating portions of the hollow anatomical structure. In certain examples, marks along the catheter shaft provide visual verification to the physician of the relative position of the therapeutic element of the catheter. Embodiments of indexing devices may include pairs of rings and/or hinged arms that move a catheter a desired indexed position between successive treatments.

  • Publication number: 20070016272
    Abstract: A catheter includes multiple primary leads to deliver energy for ligating a hollow anatomical structure. Each of the primary leads includes a resistive element located at the working end of the catheter. Separation is maintained between the leads such that each lead can individually receive power. The catheter can include a lumen to accommodate a guide wire or to allow fluid delivery. Energy is applied until the diameter of the hollow anatomical structure is reduced to the point where occlusion is achieved. In one embodiment, a balloon is inflated to place the resistive elements into apposition with a hollow anatomical structure and to occlude the structure before the application of energy. The inflated balloon impairs blood flow and facilitates the infusion of saline, or medication, to the hollow anatomical structure in order to reduce the occurrence of coagulation and to improve the heating of the structure by the catheter.

  • Publication number: 20050080374
    Abstract: The present invention provides an apparatus and method for induction of therapeutic hypothermia of the heart by selective hypothermic perfusion of the myocardium through the patient's coronary arteries. The apparatus consists of a guiding catheter into which blood is drawn from the aorta, directed over a heat exchanger and expelled directly into a coronary artery.

  • Publication number: 20050004503
    Abstract: An apparatus and method are described for quickly inducing therapeutic hypothermia of the heart by perfusing the myocardium with hypothermic fluid in alternatingly antegrade and retrograde directions. The apparatus and method provide rapid cooling of the affected myocardium to achieve optimal myocardial salvage in a patient experiencing acute myocardial infarction. The therapeutic hypothermia system includes one or more coronary artery perfusion catheters, a coronary sinus perfusion catheter and a fluid source for delivering a hypothermically-cooled physiologically-acceptable fluid, such as saline solution, oxygenated venous blood, autologously-oxygenated arterial blood and/or an oxygenated blood substitute. The system may also include one or more guidewires, subselective catheters and/or interventional catheters introduced through a lumen in one or more of the perfusion catheters.

  • Publication number: 20040158191
    Abstract: An apparatus and method are described for efficiently cooling the myocardium while minimizing blood dilution as well as volume buildup within the patient. A flow of cooled fluid is conducted through a percutaneously introduced catheter into the aorta where only a portion thereof is discharged while the remainder is withdrawn from the patient. The much greater flow rate through the catheter that can thereby be maintained without adverse physiological effect serves to minimize the heat gained by the fluid as a result of the catheter's immersion in blood at body temperature. By arranging the catheter such that the return flow surrounds and thereby insulates the supply flow, even colder fluid can be delivered to the myocardium.
