SURGICAL RETRIEVAL DEVICE RADIALLY DEPLOYABLE FROM A COLLAPSED POSITION TO A SNARE OR CAUTERIZATION LOOP
First Claim
1. A surgical apparatus for deployment from a distal end of a catheter having a camera or lens in communication with a display providing remote viewing of procedures, comprising:
- a loop, said loop having a first end opposite a second end;
a control wire engaged at said second end of said loop;
said control wire providing means for translation of said loop within a lumen of said catheter between a first end and said distal end;
a plurality of radially positionable shaped members in operative engagement at a respective first ends, to one of said loop or said control wire, said shaped members formed of insulated or of 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;
means to restrain said shaped members in said collapsed position;
means to bias said members from said collapsed position to said deployed position;
said loop and shaped members transnationally 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 positioned 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 means to restrain said shaped members from said collapsed position;
said loop uninsulated and energizable for cauterization on a contact with tissue, in either of said first position or said second position, with said shaped members concurrently in said collapsed position;
said shaped members in said collapsed position during said cauterization enabling a view unobstructed by said shaped members for communication to said remote viewing, during any said cauterization; and
said shaped members translated to said second position, being movable to said deployed position forming said capture component, subsequent to a release of said means to restrain said shaped members in said collapsed position.

Abstract
A surgical instrument featuring a combination cauterizing and surgical capture component. The instrument is deployable from a distal end of a lumen to a first position partially exposing a cauterizing loop and having restrained radially deployable members wherein a plurality of cauterizations may be performed with said cauterizing loop in an unobstructed view of a camera or lens. The instrument is deployable to a second position fully translated from the lumen whereafter the plurality of radially positionable members may be released by activation of a release member allowing the biased members to deploy radially around an axis running through the loop.

5. A method of forming a surgical apparatus for deployment from a distal end of a catheter and having a loop operatively engaged to a control wire adapted for translation through a lumen, and having a plurality of radially positionable shaped members, each said member having a collapsed position held adjacent to said loop and in a contact with said loop or an adjacent said member by a means for restraint, and each said member having a deployed position radially spaced around a center axis to define a capture component, comprising:
-
forming said planar loop; engaging said loop to a control wire; forming said plurality of radially positionable shaped members using memory shape material in a deployed position radially positioned around a center axis extending from said control wire; rotating said shaped members adjacent to said loop into said collapsed position; employing a releasable means for restraint to maintain said members adjacent to said loop; and engaging a release to said releasable means for restraint which when activated allows movement thereof to said deployed position. - View Dependent Claims (6)
