Abstract: A medical device for manipulation of material in a tissue includes a sheath, an object engaging unit, and a flexible coupler. The object engaging unit has an operative end and a base. The flexible coupler includes a longitudinal axis and a distal portion; the distal portion is associated with the base of the object engaging unit and is bendable in an arc to various ranges. The flexible coupler confers lateral movement on the object engaging unit thereby permitting manipulation and/or retrieval of material lodged or disposed in heretofore often inaccessible tissue regions. The sheath has a longitudinal axis and a lumen. The object engaging unit is in a collapsed position when it is within the sheath lumen and an expanded position when it is extended beyond the sheath.

Abstract: A medical retrieval device, and related method, for removing material (such as calculi and stones) from the body of a patient has the ability to capture and readily release material. The retrieval device includes a basket having at least one loop with first and second ends including a plurality of bead elements. The first end of the loop is immovable and the second end of the loop is slideably movable.

Abstract: A medical retrieval device has a multi-prong retrieval assembly. The multi-prong retrieval assembly has a first position, in which the retrieval assembly extends from the distal end of the sheath to form an open ended grasping device, and a second position, in which the retrieval assembly extends from the distal end of the sheath to form a substantially close ended basket-type retrieval device. When the retrieval assembly is used as a basket-type retrieval device, the distal ends of the prongs of the retrieval assembly that form the basket are not connected to each other. Thus, captured objects may be released by the operator, or by applying sufficient force to separate one or more of the prongs.

Abstract: A medical device includes a sheath having a lumen and an elongate member disposed within the lumen of the sheath. The elongate member is moveable relative to the sheath and includes a retrieval assembly. The retrieval assembly has a collapsed position within the lumen of the sheath and an expanded position when extended beyond a distal end of the sheath. The elongate member defines a lumen configured to receive a laser.

Abstract: Devices and related methods of use are provided for the entrapment and removal of various unwanted objects present within the body's anatomical lumens. In an embodiment of the present disclosure, the device includes a handle and a core element having a substantially linear first section and a second section capable of transitioning between an expanded configuration and a substantially linear configuration.

Abstract: A medical device for manipulation of material in a tissue includes a sheath, an object engaging unit, and a flexible coupler. The object engaging unit has an operative end and a base. The flexible coupler includes a longitudinal axis and a distal portion; the distal portion is associated with the base of the object engaging unit and is bendable in an arc to various ranges. The flexible couple confers lateral movement on the object engaging unit thereby permitting manipulation and/or retrieval of material lodged or disposed in heretofore often inaccessible tissue regions. The sheath has a longitudinal axis and a lumen. The object engaging unit is in a collapsed position when it is within the sheath lumen and an expanded position when it is extended beyond the sheath.
