Patent ID: 8021372

Claim:
A medical retrieval device for extracting an object from the urinary or biliary system comprising: a sheath and a drive wire each having a proximal end and a distal end, said drive wire slidably extending through said sheath; an object entrapping assembly connected to said distal end of said drive wire for entrapping said object, said object entrapping assembly comprising at least three elements forming a three-dimensional basket for entrapping said object, said sheath for collapsing said object entrapping assembly when retracted into said sheath; and a handle assembly located at the proximal ends of said sheath and said drive wire, said handle assembly comprising: a base configured as a handheld body having a single defined shape; a sliding portion connected to said sheath, a portion of said sliding portion movable along an outer surface of said base; and a spinner located proximate to and outside an end of said base and fixed longitudinally relative to said base; said drive wire connected to said spinner, whereby rotational movement of said spinner relative to said base enables rotational movement for positioning of said object entrapping assembly relative to said sheath; and said sheath connected to said sliding portion, whereby longitudinal movement of said sliding portion relative to said base enables longitudinal movement of said sheath relative to said object entrapping assembly for collapsing said object entrapping assembly when retracted into said sheath, whereby said handle assembly provides for independent rotational positioning and actuating of said object entrapping assembly.
