1. A medical device, comprising:
- an elongate member including a longitudinal axis; and
a retrieval assembly extending distally from the elongate member, wherein the retrieval assembly and the elongate member are a continuous piece of a single material,the retrieval assembly further comprising a distalmost end and a leg including a free distal end, the leg configured to transition from a substantially straight configuration when the retrieval assembly is in a collapsed state to a substantially curled configuration when the retrieval assembly is in an expanded state,wherein, in the substantially straight configuration, the free distal end terminates at the distalmost end of the retrieval assembly,wherein, in the substantially curled configuration, the free distal end is proximal the distalmost end of the retrieval assembly, and the leg defines a substantially enclosed area, andwherein, in the substantially curled configuration, the leg intersects the longitudinal axis of the elongate member and defines a bend having a point directed towards the substantially enclosed area.

Abstract
In an exemplary embodiment of the present disclosure, a medical device includes an elongate member and a retrieval assembly. The retrieval assembly extends distally from the elongate member and is formed from a same piece of material as the elongate member. The retrieval assembly is formed by removing at least a portion of the same piece of material.

15. A medical device, comprising:
-
an elongate member including a longitudinal axis; and a retrieval assembly extending distally from the elongate member, the retrieval assembly comprising a distalmost end and a leg including a free distal end, the leg configured to transition from a substantially straight configuration when the retrieval assembly is in a collapsed state to a substantially curled configuration when the retrieval assembly is in an expanded state, wherein, in the substantially straight configuration, the free distal end terminates at the distalmost end of the retrieval assembly, wherein, in the substantially curled configuration, the free distal end is proximal the distalmost end of the retrieval assembly, and the leg defines a substantially enclosed area, and wherein, in the substantially curled configuration, the leg intersects the longitudinal axis of the elongate member and defines a bend greater than 90 degrees and having a point directed towards the substantially enclosed area. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A medical device, comprising:
-
an elongate member including a longitudinal axis; and a retrieval assembly extending distally from the elongate member, wherein the retrieval assembly and the elongate member are a continuous piece of a single material, the retrieval assembly further comprising a distalmost end and a leg including a free distal end and a proximal end at the distal end of the elongate member, the leg configured to transition from a substantially straight configuration when the retrieval assembly is in a collapsed state to a substantially curled configuration when the retrieval assembly is in an expanded state, wherein, in the substantially straight configuration, the free distal end terminates at the distalmost end of the retrieval assembly, wherein, in the substantially curled configuration, the free distal end is proximal the distalmost end of the retrieval assembly, and the leg defines a substantially enclosed area, and wherein, in sequential order along the leg from the a proximal end to the free distal end in the substantially curled configuration, the leg intersects the longitudinal axis of the elongate member, defines a bend having a point directed towards the substantially enclosed area, and reaches the distalmost end of the retrieval assembly. - View Dependent Claims (23, 24, 25)
