Abstract: A quick to connect and quick to disconnect fluid coupling includes a clip, a male stem having an annular clip groove adapted to receive the clip, a female port having a step groove adapted to receive the clip upon insertion of the stem into the port, and a sleeve slideably disposed about the stem adapted to abut the clip and minimize shuttling of the stem within the port. The sleeve may be biased toward the clip by a dust seal abutting a shoulder of the sleeve distal from a lead-in end of the sleeve abutting the clip. Also, the sleeve may radially retain the clip, compressed in an annular groove of the stem, and/or the sleeve abutting the clip may stabilize the clip and axially align the clip with the stem, for insertion of the stem into the port.

Abstract: A stent having variable thickness with improved radiopacity, MRI compatibility, radial stiffness, and flexibility and to the method of making such stents.

Abstract: A coupling assembly is provided herein which generally includes a female coupler selectively interconnected to a male coupler to provide sealing engagement. In one embodiment, the female coupler and the male coupler are secured together by a pressure activated locking assembly which prevents disengagement of the male and female coupling until the internal pressure in the coupling is reduced to a predetermined level.

Abstract: A coupling assembly is provided that generally includes a female coupling selectively interconnected to a male coupling to provide sealing engagement. In one embodiment, the female coupling and the male coupling are secured together by a mechanical locking mechanism that is disengaged with a release mechanism. To prevent inadvertent disengagement, a secondary locking device or spacer is provided which substantially prevents the release mechanism from disengaging the locking mechanism.

Abstract: The present invention is an improved quick connect coupling of the type having a clip, a port having an interior annular groove adapted to support the clip, a forward cylinder, a rear cylinder, and a first transition ramp, and defines a port peak distance. The coupling is also of the type having a sealing element. Additionally, the coupling is of the type having a stem having a male connection portion including a forward annular seal groove adapted to receive the sealing element, an annular lead-in surface, a leading support cylindrical surface, a following support cylindrical surface, a camming ramp, and defines a stem peak distance.

Abstract: The present invention is an improved quick to connect and quick to disconnect fluid coupling of the type having a clip, a male portion having an annular groove adapted to receive the clip, a female portion, and a sealing element. It is improved by the female portion having a dual function frustoconical portion adapted to compress the sealing element during joinder of the male portion with the female portion as well as to compress the clip into the annular groove in preparation of separating the male portion from the female portion. Further, a sleeve is slideably placed about the male portion and adapted to capture the clip compressed within the annular groove.

Abstract: A radiopaque stent may be prepared by providing a stent preform, providing a particulate radiopaque material on at least a portion of the stent preform, pressing the particulate radiopaque material into a desired portion of the stent preform and processing the stent preform into a stent.

Abstract: Sound absorbing board (10) is made from recycled high density foam granulate (12) that has been mixed with a binder (14) and consolidated under pressure. Pores (16) are present in spaces between the granules. Each granule includes small pores (18). Sound is absorbed by thermal diffusion and viscous friction.
