Patent ID: 7559934

Claim:
A medical retrieval device for capturing material in the body of a patient, comprising: at least two loops, each of the at least two loops comprising a plurality of beads, a first end, and a second end, the first end of at least one loop being fixed and the second end of the at least one loop being slideably moveable relative to the first end, slideable movement of the second end of the at least one loop moving the at least one loop for capturing material in the body of the patient; a tapered distal tip linking the at least two loops, the at least one loop being slideably moveable relative to the tip, the tip having a proximal-most end and a side surface extending distally therefrom, the side surface defining a plurality of apertures; a sheath having a distal portion, a proximal portion, and defining a lumen; and wherein the at least two loops comprise two positions, a retracted position wherein the loops are constrained within the lumen of the sheath, and a deployed position wherein the loops are extended beyond the distal portion of the sheath, and the deployed position comprises a deployed expanded position wherein the loops are expanded, and a deployed collapsed position wherein the loops are collapsed.
