Patent ID: 8870895

Claim:
A medical retrieval device for extracting an object 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 the 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 having a proximal end and a distal end defining a fixed longitudinal length and configured to be held in a single hand; an actuation mechanism disposed between the proximal end and the distal end of the base, and operably engaged to the sheath, enabling a longitudinal movement of said object entrapping assembly into and out of said sheath; and means for rotating the object entrapping assembly for rotational positioning of said object entrapping assembly independent of said longitudinal movement of said actuation mechanism; whereby said handle assembly provides for independent rotation and actuation of said object entrapping assembly.
