摘要:
A hemostasis seal configured for use in a splittable hemostasis valve, hub, or introducer sheath to permit passage of a medical device therethrough. The seal provides a substantially fluid-tight seal around the medical device without causing excessive frictional resistance that would otherwise unduly restrict movement of the medical device through the seal. In one embodiment, the seal includes first and second resilient seal portions each having a contoured mating surface to provide a first fluid seal with respect to the medical device. The seal also may include one or more projecting portions and one or more mating receiving portions which interact to provide a second fluid seal with respect to the medical device.

Embodiments of the present invention provide compositions including a complexes of papillomavirus capsid polypeptide L2 and polypeptide including an immunotherapeutic epitope, and GST fusions thereof. Other embodiments also provide complexes comprising chimeras of papillomavirus L2 polypeptides non-covalently associated with papillomavirus L1 polypeptides, and GST fusions thereof. These compositions may be used to elicit immune responses in a patient to papillomavirus. Therapeutic and prophylactic vaccines for the prevention and treatment of viral infection, especially papillomavirus infection and cervical cancers and warts associated therewith, made from compositions of this invention, are also disclosed. Nucleic acids and expression vectors coding for compositions are also disclosed.

A suture anchor for securing soft tissue to bone may include a threaded body, a head extending along a longitudinal axis, and a plurality of eyelets that extend though the anchor head and that are each configured to receive a suture. The eyelets are offset from one another along an axis that is transverse to the longitudinal axis of the suture anchor. Each eyelet may have a desired shape and cross section. Surgical kits including one or more suture anchors and one or more surgical tools are also described.

The present invention is device for delivering an electrode into a lateral vein of the coronary sinus. The device includes a support structure, a stent, a tether coupled to the stent and a removable sheath disposed about the stent. The stent is carried on the support structure and is deployable from a first collapsed configuration to a second expanded configuration for engaging the inner walls of the selected vessel. The sheath is sized to retain the stent in the first collapsed configuration. The electrode is carried on the stent or on a lead threaded over the tether.

A bone screw driver (12) for inserting a bone screw (14) into a bone region (218A) includes a driver shaft (12B) that selectively engages the bone screw (14). The bone screw (14) includes a screw threaded region (14A) and a screw engagement region (14B). The screw engagement region (14B) includes a screw shaft (14D) and an engager ring (14E). The driver shaft (12B) includes a shaft aperture (322), a first resilient member (324A), and a first shaft projection (326A). The shaft aperture (322) receives at least a portion of the screw shaft (14D), the first resilient member (324A) engages the screw shaft (14D) to inhibit movement of the screw shaft (14D), and the first shaft projection (326A) engages the engager ring (14E) so that rotation of the driver shaft (12B) results in rotation of the bone screw (14). With this design, in certain embodiments, the bone screw (14) can be removed with the bone screw driver (12) from a screw retainer (16) that retains the bone screw (14), and inserted into the bone region (218A) without the physician contacting with the bone screw (14). This reduces the likelihood of contaminating the bone screw (14) and increases the likelihood of success for the procedure.

An adjustable armrest assembly for a chair includes a mounting member connected to the chair. The mounting member has an upper base. A first horizontal slide element is slidably mounted to the upper base and is adjustably slidable in a first direction with respect to the upper base. The first slide element is restrained after adjustment with respect to the upper base by frictional engagement between the upper base and the first slide element. A second horizontal slide element for slidably mounting to the first slide element is slidable in an arcuate path crossing the first direction. The second slide element is restrained after adjustment with respect to the first slide element by frictional engagement between the second slide element and the first slide element.

Some embodiments relate to a method of implanting a cardiac lead. An expansion module is implanted in a target region within vasculature, the target region being defined by a portion of a brachiocephalic vein and a portion of a corresponding subclavian vein. The expansion module is transitioned from a collapsed state to an expanded state within the target region to contact the vasculature. A cardiac lead is implanted through the expansion module, the cardiac lead defining an intermediate section corresponding to the target region. The intermediate section of the cardiac lead includes a surface treatment adapted to reduce at least one of cell proliferation, thrombosis, fibrosis, and inflammation at the target region.
摘要:
A combined prime valve and electrical pressure control apparatus including a prime valve actuator, an electrical pressure control actuator, and a control housing containing the actuators, with each coupled to a single shaft having a cam assembly for selectively actuating the control apparatus to one of a prime mode and a spray mode and the electrical pressure control is operable within a range of pressure settings by movement of the shaft while the control apparatus remains in the spray mode. The actuators are oriented diametrically opposite and offset along an axis of the single shaft with respect to each other, and contact the cam assembly and respectively contact a lever for a prime valve and a pressure switch carrier. A setscrew in the carrier provides adjustment of the pressure at which the switch is actuated.
