Abstract:
1. A medical system for use in reducing the size of an internal tissue opening comprising: a delivery sheath having a distal end and a proximal end, wherein said delivery sheath includes a lumen defining an axis extending from said proximal end toward said distal end; an electrode including one or more arms, said one or more arms being configured to be extended from said distal end of said delivery sheath to be received through an internal tissue opening, said electrode being configured to delivery radio frequency energy to tissue which is in contact with at least one of said one or more arms; a first device being positioned proximate to at least one of said arms; and a second device, wherein when said electrode is positioned against a first side of the internal tissue opening and said second device is positioned proximate a second opposing side of the internal tissue opening, said first and second devices usable to measure a tissue characteristic enabling a practitioner to determine a radio frequency dose for use in reducing the size of the internal tissue opening, wherein said delivery sheath includes a second lumen, the second lumen being non-concentric relative to the axis defined in the lumen of the delivery sheath, wherein said second device is positioned within said second lumen and is capable of movement independent of said electrode and said delivery sheath.
