The air spring unit includes a rolling tube having a flared terminal end that extends over a damper tube associated with the damper unit. The damper tube has a circumferential groove formed in an outer diameter of the damper tube. A retaining ring has a greater outer diameter than the outer diameter of the damper tube and is positioned in the circumferential groove. A base has an inner diameter less than the outer diameter of the retaining ring, and an outer diameter smaller than the predetermined diameter of the flared free end, and is supported on the retaining ring. A torsion element fits around the damper tube and within the flared free end.

Abstract: Catheterization methods and apparatuses allow sensing of pressures inside the heart and for removing air from catheters. A delivery system can use the same components that are used to deliver a valve repair or replacement device to measure the pressure in the atrium or other heart chamber. A pressure sensor can be included in one of the catheters of the delivery system or pressure can be sensed through the same port that is used to flush a catheter. The delivery system can be inserted into the heart, delivering the valve repair or replacement device to the native valve, such as the mitral valve, the tricuspid valve, the aortic valve, or the pulmonary valve.

Abstract: A valve repair delivery handle includes a housing, an actuation control mechanism, and a clasp control mechanism. The actuation control mechanism includes a knob and an actuation tube. The knob is rotatably coupled to the housing. The actuation tube is coupled to the knob such that rotation of the knob in a first direction moves the actuation tube distally relative to the housing and rotation of the knob in a second direction moves the actuation tube proximally relative to the housing. The clasp control mechanism is coupled to the housing.

Abstract: A solenoid assembly made with a one-piece metallic valve body having: a closed end; an open end; a central opening that communicates with multiple ports and an attachment portion adjacent to the open end. A movable armature positioned in the central opening has a free end that extends beyond the open end. A coil bobbin receives the free end of the movable armature and acts in response to electrical signals. The housing enclosing the coil bobbin attaches to the valve body to unify the coil bobbin and valve body as a solenoid.

Abstract: An implantable prosthetic device can include a spacer member, a plurality of anchors, and a plurality of clasps. The spacer member can be configured to be disposed between native leaflets of a heart. The anchors can be coupled to the spacer member and configured to secure the native leaflets against the spacer member. The clasps can be coupled to a respective anchor and configured to secure the native leaflets to the anchors. The clasps can be independently movable between an open configuration and a closed configuration.

Abstract: A delivery system includes an elongate shaft, a handle, a first clasp control member, a second clasp control member, and an actuator. The handle is connected to a proximal portion of the elongate shaft. The first and second clasp control members each extend into a distal portion of the elongate shaft, through at least a portion of the elongate shaft, out of the proximal portion of the elongate shaft, and through the handle. The actuator is coupled to the handle and has a first side portion connected to the first clasp control and a second side portion connected to the second clasp control.

Abstract: A tape 400 or wrap is provided which includes first and second elongated elastic layers 345, 346 sized to conform to the shape of a portion of the external skin of the body of a wearer; and a heated area comprising an exothermic material 310 sandwiched between said first and second elastic layers 345, 346, wherein said exothermic material 310 is activated by exposing said exothermic material 310 to oxygen; wherein said tape 400 or wrap has a elasticity of at least about 10-90% and said heated area is capable of substantially expanding and contracting with the tape or wrap. Methods of using the tape 400 or wrap are also provided.

Abstract: This invention provides a method and system for providing an oxygen-enriched air stream to the cabin and/or internal combustion engine of a vehicle. The benefits of such an approach include increased fuel efficiency and reduced emissions in the internal combustion engine and increased driver alertness and comfort for the vehicle operator. The oxygen-enriched air stream is provided by a membrane separation system, a pressure swing adsorption system, vacuum swing adsorption, or other methods. The delivered oxygen-enriched air is controlled to a prescribed level using sensors, valves, and controllers.

Abstract: This invention provides a method and system for simultaneously increasing fuel efficiency and reducing pollutant emissions by introducing oxygen-enriched air, achieved by either removing nitrogen or adding oxygen, into the intake system of a four-stroke internal combustion engine. The oxygen-enriched air may also be combined with normal air drawn into the combustion chamber during the intake stroke.
