    摘要： A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve may include a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A system and method for deployment includes an integrated handle shaft and balloon catheter. A safety member disposed between the balloon catheter and handle shaft prevents premature catheter advancement prior to heart valve placement at the annulus, and also may prevent premature balloon inflation prior to full catheter advancement.

    摘要： A controlled volume inflation-deflation device to inflate a balloon to occlude a blood vessel by dialing a knob that locks at rotational positions to locate a plunger at equally spaced locations within a syringe of the inflation-deflation device. The inflation-deflation device includes a releasable latch to lock the proximal and distal housings together to hold the plunger forward for occlusion, and to separate and hold the proximal and distal housings to retract the plunger for perfusion. When the inflation-deflation device is returned to the latched position, the balloon is re-inflated to its previous occlusive diameter. Also, an extension tube made of a lower modulus outer material co-extruded over and miscible with a higher modulus inner material may be used. The balloon may have tapered ends and a cylindrical center portion so that it increases by more equal increments in outer diameter to incremental equal increases in inflation volume.

    摘要： This invention is directed to a member which is mounted on an elongated intraluminal device such as a catheter or a guidewire, preferably the proximal portion thereof, which releasably holds at least one turn of a coiled product. The coiled product may be the intraluminal device on which the fixture is mounted or it may be a separate product. In one embodiment of the invention, the turn holding member has a body and at least one flexible arm which holds a turn against the body of the fixture. In another embodiment of the invention, the holding member is a tubular element having a wall portion with a spirally shaped cutout through which a turn of coiled product can be advanced into the inner lumen or the tubular element.

The balloon may have tapered ends and a cylindrical center portion so that it increases by more equal increments in outer diameter in response to incremental equal increases in inflation volume.
