Abstract
This document describes implantable medical devices and methods of using such devices. The implantable medical devices include a cardiac lead sized for insertion in a cardiac cavity, the cardiac lead having a distal end and a proximal end and a lead body extending therebetween, a heat exchange module disposed at the distal end of the lead body, the heat exchange module comprising an enclosure having a first surface and a second surface, and one or more temperature sensors located within the enclosure.
Claims17
An implantable medical device comprising:
- a cardiac lead sized for insertion in a cardiac cavity, the cardiac lead having a distal end and a proximal end and a lead body extending therebetween;
- a heat exchange module disposed at the distal end of the lead body, the heat exchange module comprising an enclosure having a first surface and a second surface;
- one or more temperature sensors located within the enclosure;
- and
- a delivery tool system comprising:
- a sheath comprising a proximal end, a distal end, and an elongate body extending therebetween, the sheath defining a region configured to slidably receive the lead body, the distal end of the sheath configured to exert a pushing force against the heat exchange module;
- and
- a case comprising:
- (i) a distal end that is shaped generally rectangular in correspondence to the heat exchange module and that is sized for releasably enclosing the heat exchange module and (ii) an elongate body defining a lumen or a surface configured to slidably receive the sheath.
A method of treating a cardiac arrythmia in a patient in need thereof, the method comprising:
- making an incision into a pericardial tissue of the patient;
- inserting, using a delivery tool system, an implantable medical device through the incision, the implantable medical device comprising:
- a cardiac lead sized for insertion in a cardiac cavity, the cardiac
- lead having a distal end and a proximal end and a lead body extending therebetween;
- a heat exchange module disposed at the distal end of the lead body,
- the heat exchange module comprising an enclosure having a first surface and a second surface;
- and
- one or more temperature sensors located within the enclosure;
- securing the heat exchange module to a surface of a cardiac tissue, wherein the delivery tool system comprises:
- a sheath having a proximal end, a distal end, and an elongate body extending therebetween, the sheath defining a region configured to slidably receive the lead body, the distal end of the sheath configured to exert a pushing force against the heat exchange module;
- and
- a case having:
- (i) a distal end that is shaped generally rectangular in correspondence to the heat exchange module and that is sized for releasably enclosing the heat exchange module and (ii) an elongate body defining a lumen or a surface configured to slidably receive the sheath;
- and
- cooling the first surface of the implantable medical device to a therapeutic temperature for a therapeutic period of time.
