FOAM ELECTRODE AND METHOD OF USE THEREOF DURING TISSUE RESECTION
First Claim
1. A method of resecting a portion of tissue to be removed from a portion of the tissue to be retained within a patient, comprising:
- absorbing an electrically conductive fluid into a hydrophilic electrode;
conveying electrical energy to or from the hydrophilic electrode while being moved in proximity to the tissue along a resection line, whereby tissue adjacent to the resection line is coagulated; and
separating the tissue along the resection line to resect the tissue portion to be removed from the tissue portion to be retained.

Abstract
Assemblies and methods are provided for resecting a portion of tissue to be removed (e.g., unhealthy tissue, such as cancerous tissue) from a portion of the tissue to be retained (e.g., healthy tissue) within a patient is provided. An electrically conductive fluid, such as saline, may be absorbed into a hydrophilic electrode. Electrical energy (e.g., radio frequency (RF) energy) is conveyed to or from the hydrophilic electrode while being moved in proximity to the tissue along a resection line, whereby tissue adjacent to the resection line is coagulated. A resection member, such as a blunt resection member or a resection electrode, which may be on the same device as the hydrophilic electrode, is used to separate the tissue along the resection line to resect the tissue portion to be removed from the tissue portion to be retained.
