摘要:
Apparatus and methods for perfusing ischemic myocardium, and optionally, for reducing the load on a patient's left ventricle, are provided using a inlet conduit having an inlet end configured for insertion into an oxygenated blood source, including without limitation, the left atrium, left ventricle, aorta, pulmonary vein, subclavian artery, brachiocephalic artery, radial artery or femoral artery, coupled to an outlet conduit having an outlet end configured for insertion into the coronary venous vasculature via the coronary ostium. The inlet conduit may include a stylet or elastomeric sleeve that facilitates placement, while the outlet conduit may include a valve for limiting a peak pressure attained in the coronary venous system. A motor-driven or hydraulically-actuated pump optionally may be coupled in the flow path, and control circuitry provided to control the pump with a user selected duty cycle.
摘要:
Methods and apparatus are provided for use in intraoperative and percutaneous procedures for supplying long-term retrograde perfusion of the myocardium via one or more conduits disposed between the left ventricle and the coronary venous vasculature. The conduits are of a selected size and number, and portions of the venous vasculature or coronary ostium are partially or completely occluded, to maintain a parameter related to the pressure attained in the venous vasculature to a value less than a predetermined value.
摘要:
Methods and apparatus for supplying retrograde perfusion of chronically ischemic myocardium by forming one or more transmural passageways between a cardiac chamber and the coronary venous vasculature. The placement, size and number of the passageways are selected, and portions of the venous vasculature or coronary ostium optionally partially or completely occluded, to maintain a parameter related to the pressure attained in the venous vasculature to a value less than a predetermined value.

A push-in connector provides for easy manufacturing and assembly using a flat-stamped flexible retainer clip. The retainer clip is inserted into the connector and flexes to snap-fit within in the connector. The flex of the clip also flexes wings of the clip which engage with a receiving boss. The flexion of the clip allows for easy push-in of the connector and sufficient resistance to accidental pull-out. The push-in connector design eliminates the need for screw-mounting of the connector. The connector assembly may be manufactured for use in connection with a variety of ball studs, as well as other items such as shafts of various objects and wires, or may be used a fastener.

The device includes tethered plugs that may be reversibly inserted into the VAS to provide contraception. The method includes a procedure for inserting and removing the device.
摘要:
An implantable medical device and method for adjustably restricting a selected body lumen such as a urethra or ureter of a patient to treat urinary incontinence or ureteral reflux. The device includes an adjustable element and a tubular elongate body, where the adjustable element includes a chamber and the tubular elongate body includes at least a first interior passageway which extends longitudinally in the tubular elongate body from a first opening at the proximal end to a second opening in fluid communication with the chamber. Fluid volume passed through the first passageway is used for adjustably expanding or contracting the adjustable element. The implantable medical device further includes a sheath and a sleeve, where the sheath includes a wall having an inner surface which defines a channel through which at least a portion of the implantable device and the sleeve can pass. Alternatively, the implantable medical device includes a tip suitable to penetrate tissue so that the implantable medical device can be implanted within the tissue of a patient.
摘要:
A connector has a female receptacle and/or a male plug, or combination thereof. The female receptacle has a sleeve for holding prongs plugged into the receptacle and a mechanism for applying pressure against the sleeve such that actuation of the collar causes the socket to clamp to the prong. The male plug has a prong for insertion into a socket or other receptacle and a mechanism for applying pressure against the prong to clamp the prong within the socket or other receptacle.

A device (10) is disclosed for biocidal treatment of vegetation and/or pests, the device (10) comprising an inner tube (30) connectable to a source of one of heated pressurised gas and heated pressurised water, an outer tube (26) disposed over the inner tube so that a space is defined between the inner tube and the outer tube, and a wand (22) in communication with the inner tube (30) and the outer tube (26). The wand (22) has an outlet aperture and the outer tube (26) is connectable to a source of the other of heated pressurised gas and heated pressurised water. The heated air and water mix in the wand (22) immediately prior to passing through the outlet aperture.

A bottle cap remover includes a pair of axially nested socket sections of different diameters depending axially from a larger-diameter grasping section. Each of the socket sections includes frictional gripping members along their inner walls that are adapted to frictionally engage different sizes and types of metal and plastic bottle caps, thereby to enable the user to twist off and remove the bottle caps by applying a relatively small twisting force to the grasping section.
