Patent ID: 8211115

Claim:
A medical device, comprising: an elongate member defining a lumen; and a tipless basket having a proximal end and a distal end, the basket being retractable within and extendable from the lumen, the basket including a plurality of proximal legs extending from the proximal end of the basket and a plurality of distal legs extending to the distal end of the basket, each of the plurality of proximal legs being connected to an end of at least two of the plurality of distal legs between the proximal and distal ends of the basket such that the plurality of distal legs are not directly attached to any material of the medical device other than the proximal legs, the basket including a distalmost end consisting of the plurality of distal legs, each individual distal leg being separated from, not meeting, and not crossing each other when extended from the lumen, wherein the plurality of proximal legs and the plurality of distal legs are a continuous piece of a single material, wherein each of the plurality of distal legs is thinner than the rest of the continuous piece of the single material, wherein, in a first position when the basket is at least partially withdrawn into the lumen, the ends of one of the plurality of distal legs are closer together than in a second position when the basket is at least partially extended from the lumen.
