Abstract
A method and system for achieving hemostasis (the stoppage of bleeding) is described. RF (radio frequency) energy is used to ablate the surface of tissue to stop bleeding. The depth of destruction of the tissue can be controlled so as to desiccate and coagulate the tissue. In one implementation, an electrode carrier including bipolar electrodes is applied to the tissue, and RF energy transmitted through the bipolar electrodes to ablate the tissue. A layer of desiccated tissue can be created as well as coagulation of the tissue to achieve hemostasis.
Claims2
1-31. (canceled)
An apparatus for substantially achieving hemostasis by tissue ablation, comprising:
- a base member;
- an electrode carrier attached to a surface of the base member, the electrode carrier including one or more bipolar electrodes that are configured to connect to a source of radio frequency energy;
- a vacuum line configured to connect to a vacuum source and to draw moisture away from the one or more bipolar electrodes during tissue ablation;
- and
- a controller electrically coupled to the electrode carrier and configured to control the delivery of radio frequency energy to the one or more bipolar electrodes such that tissue in contact with the electrode carrier can be ablated to a desired depth of destruction to achieve substantial hemostasis.
