Medical retrieval devices
First Claim
1. A medical retrieval device, comprising:
- an elongated member having first and second end portions and a middle portion, said elongated member being configured such that said first and second end portions are proximal one another and extend substantially parallel to one another along a longitudinal axis;
a sheath configured to receive at least a portion of the first and second end portions; and
a handle portion separate from and associated with the elongated member and the sheath, the handle portion being operable to cause relative longitudinal movement between the handle portion, the sheath and the first and second end portions, the handle portion comprising;
a housing enclosing a portion of the elongate member and a portion of the sheath; and
a slide mechanism configured to simultaneously translate the sheath in a first direction and the elongate member in an opposite direction relative to the housing.
