Abstract:
1. A surgical apparatus for deployment from a distal end of a catheter, comprising: a loop, said loop having a first end, said first end opposite a second end which is operatively engaged with a control wire and configured for translation through a lumen of said catheter between an insertion end and said distal end; a plurality of radially positionable shaped members having first ends and second ends, said first ends in operative engagement, to one of said loop or said control wire, said shaped members formed of insulated or non conductive material; each respective said shaped member having a deployed position around a center axis, and having a collapsed position in a stacked configuration against a side surface of said loop; said loop and said members in said deployed position forming a basket-like capture component; means to bias said members to said deployed position; means to restrain said shaped members in said collapsed position; said loop and shaped members translationally positionable by a translation of said control wire, to a first position with a first portion of said loop adjacent to said first end thereof, deployed from said lumen and with a remainder of said loop, and said means to restrain said shaped members maintained within said lumen; said loop and shaped members positionable by a said translation of said control wire, to a second position, with said loop and said shaped members still in said collapsed position, fully deployed from said lumen at said distal end of said catheter, means for release of said shaped members from said collapsed position; said loop uninsulated and energizable for cauterization on contact with tissue, in either of said first portion or said second position at a plurality of locations with said shaped members concurrently in said collapsed position thereby providing a maximized view of each said cauterization; and said shaped members translated to said second position, releasable from said collapsed position with said means for release of said shaped members from said collapsed position to move to said deployed position to form said capture component.
