Abstract
A snare device for retrieving and/or manipulating an object within a space, such as a body lumen. In one embodiment, the snare device includes a support and a core wire. The support includes a proximal portion terminating in a proximal end, a distal portion terminating in a distal end, and a lumen, the lumen extending distally from the proximal end. The core wire is flexible and includes a proximal portion and a distal portion. The distal portion of the core wire and the distal portion of the support are complementarily shaped and are fixedly fitted together, wherein the core wire forms a loop extending away from the distal end of the support, and wherein the core wire passes through the lumen and emerges from the proximal end of the support. The distal portion of the support and the distal portion of the core wire may be complementarily dimensioned helical structures.
