Patent number: 10349959Abstract: A medical retrieval device of an embodiment of the present disclosure includes a proximal handle, a sheath, and a retrieval assembly. The sheath extends from the handle and includes a lumen and a distal end opposite the handle. The retrieval assembly is moveable relative to the sheath to achieve a collapsed position of the retrieval assembly within the lumen and an expanded position of the retrieval assembly when extended outside the lumen. The retrieval assembly includes a plurality of legs. At least one of the legs includes a wire having an inner core at least partially surrounded by an outer layer.Type: GrantFiled: September 14, 2015Date of Patent: July 16, 2019Assignee: Boston Scientific Scimed, Inc.Inventors: James A.

Patent number: 8685039Abstract: The invention relates to a medical retrieval device with a basket that has at least one leg that is frangible (i.e., easily breakable) and/or able to dissociate from at least one other leg upon the application of a predetermined force to the basket. The invention allows an operator to release captured material (e.g., a stone) from the basket when the device is still inserted in the body. In an embodiment, the basket legs associate by a magnetic interaction that can be overcome by applying a predetermined force to the basket. In another embodiment, at least a portion of at least one basket leg is made from, or coated with, a substance that is adhesive or that joins at least two legs together when the substance is solid but which melts, dissolves or weakens upon the application of an electrical, thermal or chemical change.Type: GrantFiled: January 22, 2010Date of Patent: April 1, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: William R. Little, Jason W. Kear, David W. Robertson, James Teague, James W. Riley

Patent number: 8469969Abstract: 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.Type: GrantFiled: April 22, 2010Date of Patent: June 25, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Jason W. Kear, Justin Reppert

Patent number: 7883515Abstract: A stone retrieval suction device facilitates the retention and then relocation and/or removal of objects disposed in a patient's urinary system. The device includes an elongated member for placement in a channel of a flexible ureteroscope. The elongated member defines a suction passageway which extends longitudinally therethrough. The elongated member is flexible enough to bend with the flexible ureteroscope, and it is strong enough to prevent collapse of the suction passageway when suction is provided through the suction passageway by a vacuum source. The elongated member includes a distal portion for contacting and retaining an object when the suction is provided.Type: GrantFiled: February 27, 2009Date of Patent: February 8, 2011Assignee: Boston Scientific Scimed, Inc.Inventor: Jason W. Kear
