Abstract: A hanger for pictures and the like is provided that includes at least one elongate bar. Two openings (e.g., thru-holes or slots) extend between corresponding planar front and back surfaces of the bar(s). The two openings are configured to receive fasteners for attaching the bar(s) to the support surface. The two openings are spaced from one another along the lengthwise dimension of the bar(s). Two hooks extend forward and upward from the at least one planar front surface. The two hooks are spaced from one another along the lengthwise dimension of the bar(s). Each hook includes a transition from a planar front surface of the bar(s). Methods of fabricating the hangar and methods of use are also described and claimed.

Abstract: An implantable medical device for electrical stimulation or sensing includes a body supporting at least one flexible elongate conductor element. The body includes an insulating structure that protects the flexible conductor element(s). The insulating structure is realized from multiple polymer layers wherein at least one of the polymer layers is formed from a polymer blend of a thermoplastic polyurethane material and an isobutylene block copolymer. In one particular embodiment, the insulating structure of the body includes at least a first polymer layer, a second polymer layer and a third polymer layer, where the second polymer layer covers and interfaces to the first polymer layer, and the third polymer layer covers and interfaces to the second polymer layer. The first polymer layer is formed from a thermoplastic polyurethane material. The third polymer layer is formed from an isobutylene block copolymer.

Abstract: A polymer blend is provided that includes a polycarbonate polyurethane polymer component having a water contact angle greater than 75 degrees and a polyurethane polymer component having a water contact angle less than 75 degrees. The polycarbonate polyurethane component and the other polyurethane polymer can be immiscible with respect to one another, and thus are phase separated in the polymer blend. The weight percentage of the polycarbonate polyurethane polymer component is greater than the weight percentage of the other polyurethane polymer component in the blend. The polymer blend is well suited for realizing a low friction surface of a variety of medical and non-medical devices.

Abstract: A surgical apparatus for introduction of laparoscopic instruments into an anatomical cavity through tissue at an entry site. The apparatus includes a body with a frustoconical-shaped wall. The body defines an interior cavity, an open bottom, and a substantially closed top wall with openings from which a plurality of ports extend upward therefrom. The ports are adapted to receive the laparoscopic instruments for introduction through the interior cavity and open bottom of the body into the anatomical cavity. In the preferred embodiment, the frustoconical-shaped wall of the body is placed through an incision in the umbilicus. In one aspect of the invention, the body is a unitary one-piece molded structure. A reinforcing belt or plate formed from a relatively hard material can be integral to the body.

Abstract: A stent-graft is coupled to an elongate flexible member at or near the distal end of the flexible member and configurable in both a collapsed configuration and an expanded configuration. The stent-graft includes an expandable stent fixed to the flexible member. A portion of the expandable stent defines a generally tubular structure in its expanded configuration. A porous polymeric mesh interfaces circumferentially about the portion of the stent defines a generally tubular structure. The mesh is expandable with the stent and carries at least one therapeutic agent. When the stent-graft is in its expanded configuration and contacts the treatment site, the at least one therapeutic agent is transferred to the treatment site by operation of contact between the stent-graft and the treatment site. The mesh can define distal and proximal openings that allow for fluid flow through the stent-graft when the stent-graft is in the expanded configuration.

Abstract: An improved pacemaker lead including a lead body supporting at least one flexible conductor element that provides an electrical signal path between a proximal connector element and a distal electrode. The lead body includes an insulating structure that protects the flexible conductor element(s) wherein the insulating structure is realized from a polymer blend of a thermoplastic polyurethane elastomer and an isobutylene block copolymer. The mole fraction of the isobutylene block copolymer of the polymer blend is in the range of 2-15% (most preferably on the order of 10%). The polymer blend of the insulating structure has a maximum tensile strength in the range of 20-40 MPa (most preferably in a range of 25-35 MPa). In the preferred embodiment, the hardness of the polymer blend can be characterized by a Shore hardness in a range of 70-80 A.

Abstract: An improved tool for coring a portion of one or more hair follicles incorporates a mechanism that translates distal pushing forces that are applied to its handle to concomitant rotational movement of a hollow coring needle. Preferably, the force translation mechanism is realized by a helical threaded interface or a helical square rod interface between a handle and a rotating member that supports the needle. In another aspect, the tool includes a member that supports the hollow coring needle, the member having a cut-out that provides user access to the open proximal end of the needle. The tool can be made disposable by the use of injection molded plastic materials. The hollow coring needle is preferably realized from stainless steel and an anti-wear coating (such as a titanium nitride coating, a zirconium coating, or a diamond coating). In disposable applications, the tool is packaged in a sterilized manner, which avoids the need for the practitioner to sterilize the tool before use.

Abstract: A cosmetic implant comprises a filament made from a biocompatible elastomer. The elastomeric filament can be injected or pulled under one or more wrinkles. Once implanted under the wrinkle(s), the filament lifts and supports the tissue above it. Such lifting lessens (and possibly removes altogether) the appearance of the wrinkle(s). The biocompatible elastomeric filament is preferably made from a polyolefinic copolymer material having a triblock polymer backbone comprising polystyrene-polyisobutylene-polystyrene, which is herein referred to as “SIBS”; or alternatively can be made from silicon rubber, expanded polytetrafluorethelyene (ePTFE), polyurethane, polyolefin, copolymers of nylon, copolymers of polyester, or elastin.
