First Claim
Patent Images
1. A pressure application probe for use with a surgical device, the surgical device including an elongate structure, defining a distal region, a distal region outer diameter not greater than about 5 mm and a predetermined length sufficient to allow a physician to manipulate the distal region when the elongate structure is inserted into a body cavity through an incision, and at least one energy transmission device on the distal region, the pressure application probe comprising:
- an elongate main body portion defining a distal end, a proximal end and a length of at least four inches; and
a unitary substantially c-shaped engagement device adapted to releasably engage the surgical device elongate structure and including a pair of ends defining an opening therebetween, a mid-portion secured to the main body portion and an interior region defining a size corresponding to the diameter of the distal region of the surgical device elongate structure.

21. A method of forming a lesion in tissue, comprising the steps of:
-
providing an energy transmission probe including a support member and at least one energy transmission device on the support member;
inserting the energy transmission probe directly into a bodily cavity through an incision in a patient;
positioning the energy transmission probe within the patient such that the energy transmission device is adjacent tissue;
providing a pressure application probe;
inserting the pressure application probe into the patient;
engaging the support member with the pressure application probe; and
transmitting energy to the tissue through the at least one energy transmission device. - View Dependent Claims (22, 23, 24, 25)
