Abstract
A method of preparing a target hard body tissue, such as osseous or dental tissue, to receive an implant component including; positioning an active electrode in proximity to a target tissue and proximate an electrically conductive fluid, followed by applying a high frequency voltage between the active electrode and a return electrode, the high frequency voltage sufficient to form a plasma. This plasma modifies at least a portion of the target tissue. An implant component may then be placed adjacent at least a portion of the modified target tissue.

A method of preparing a target tissue, including bone tissue and any surrounding tissue, to receive an implant component comprising:
- resecting a portion of a bone body using a mechanical device, so as to define a resected bone surface prepared to fit with an implant;
- followed by positioning an active electrode associated with an electrosurgical device in proximity to the resected bone surface and proximate an electrically conductive fluid;
- applying a high frequency voltage between the active electrode and a return electrode, the high frequency voltage sufficient to form a plasma, wherein the plasma modifies at least a portion of the tissue on the resected bone surface prepared to fit with an implant;
- and
- disposing an implant component adjacent at least a portion of the modified resected bone surface.
An electrosurgical method of treating bone tissue and any proximate tissue comprising:
- positioning an active electrode in proximity to a surface of a target bone tissue and an electrically conductive fluid;
- and
- modifying the surface of the target bone tissue so as to create a uniform and smooth contoured bone tissue surface using a plasma formed by applying sufficiently high frequency voltage between the active electrode and a return electrode to the bone tissue surface;
- and
- creating holes or divots in proximate tissues only, using the plasma so as to stimulate repair and growth of the bone tissue surface.
A method of treating bone tissue and some proximate tissue comprising:
- resecting a portion of bone tissue using a non-electrosurgical device so as to prepare a resected bone surface to fit with an implant;
- followed by positioning an electrosurgical device with an active electrode in proximity to the resected bone tissue surface;
- and
- applying a high frequency voltage between the active electrode and a return electrode, the high frequency voltage sufficient to develop a high electric field intensity associated with a vapor layer proximate the active electrode, wherein the electric field intensity stimulates the secretion of at least one growth mediator associated with bone repair at the resected bone tissue surface.
A method of preparing a target bone tissue comprising:
- positioning an active electrode in proximity to a surface of a target bone tissue and proximate an electrically conductive fluid, wherein the target tissue is being prepared to receive an implant component;
- and
- applying a high frequency voltage between the active electrode and a return electrode, the high frequency voltage sufficient to form a plasma;
- wherein the plasma applies an electrical field to at least a portion of the surface of the target bone tissue and some proximate tissues;
- wherein the plasma removes necrotic and unhealthy tissue from within and adjacent the target bone tissue so as to create a uniform smooth and sterilized bone tissue surface and creates holes or divots in some proximate soft tissues to stimulate bone repair and growth.
A method of preparing a target tissue, including bone tissue and any surrounding wound, to receive an implant component comprising:
- resecting a portion of a bone body, so as to define a resected bone surface prepared to fit with an implant;
- positioning an active electrode in proximity to the resected bone surface and proximate an electrically conductive fluid;
- applying a high frequency voltage between the active electrode and a return electrode, the high frequency voltage sufficient to form a plasma, wherein the plasma modifies at least a portion of the resected bone surface;
- and
- disposing an implant component adjacent at least a portion of the modified resected bone surface;
- wherein the resecting step and the applying step are performed using different devices.
