1. 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.

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.

30. 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. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54)

55. 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. - View Dependent Claims (56, 57, 58, 59, 60, 61, 62, 63, 64, 65)

66. 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. - View Dependent Claims (67, 68)
