Abstract:
A mechanism for coupling a first structure to a second structure may include a first member and a second member. The first member may include first and second end portions, and the first end portion of the first member may be coupled to the first structure. The second end portion of the first member may include an opening to a cavity extending between the first and the second end portions. The second end portion of the first member may include an engagement member that protrudes into the cavity. The second member also may include a first end portion and a second end portion. The first end portion of the second member may be received into the cavity. The second end portion of the second member may include an engagement structure that cooperates with the engagement member to prevent the movement of the first structure relative to the second structure.
Abstract:
A medical retrieval device may include an elongate sheath, a first and a second control wire extending through the sheath, and a basket coupled to a distal end of the first control wire. The retrieval device may additionally include an engaging member coupled to a distal end of the second control wire and the basket. The engaging member may be configured to transform from a constrained configuration within the sheath to an unconstrained configuration outside to the sheath, wherein transforming the engaging member from the unconstrained configuration to the constrained configuration may rotate the basket about an axis perpendicular to a longitudinal axis of the sheath.
