Abstract
A device and a method for shrinkage of tissue containing collagen is described. The device comprises a heating tip, a support shaft, and a control system. The heating tip comprises a heating element and a temperature sensor therein. The control system is configured to receive a temperature feedback from the temperature sensor and to regulate energy delivered to the heating element based on the temperature feedback. Heating of the tissue region causes shrinkage of collagen-containing tissue, thereby closing any perforation or opening in the tissue region.
Claims20
A device for controlled shrinkage of a tissue region containing collagen, the device comprising:
- a heating element configured to deliver heat to the tissue region;
- a support for positioning the heating element at a location to effect delivery of heat to the tissue region;
- a temperature sensor associated with the heating element;
- and
- at least one controller configured to access information related to tissue shrinkage and to regulate the temperature of the heating element.
A method of closing a perforation in a tissue region containing collagen, comprising:
- providing a tissue closure device comprising a heating tip having a heating element and at least one temperature sensor, and at least one processor for regulating energy transmission from a power source to the heating element;
- advancing the heating tip percutaneously to the perforation in the tissue region;
- delivering energy from the power source to the heating element to heat the tissue region and cause shrinkage of the collagen-containing tissue surrounding the perforation;
- monitoring a temperature of at least one of the heating tip and the tissue region using the at least one temperature sensors;
- and
- regulating energy delivered to the heating element based on at least one of the temperature of the heating tip and the temperature of the tissue region.
