Abstract: A clamping device for a shaft of a catheter can include a first member rotatably coupled to a second member. The first member can have an annular element defining a central lumen, the outer surface of the annular element having a non-circular cross-sectional profile, and the second member can define a bore into which the annular element extends, the bore having a non-circular cross-sectional profile. The device can move between a release state wherein the central lumen has a first diameter, and a clamped state wherein the central lumen has a second diameter less than the first diameter. When the clamping device is in the clamped state, the clamping device can engage an outer surface of a catheter shaft and when the clamping device is in the release state, the clamping device can be moved along a length of the catheter shaft.

Abstract: A clamping device for a catheter shaft can include a first member having a first indicator surface and defining a first inner bore having a non-circular cross-sectional profile, and a second member having a second indicator surface, and an extending annular element defining a second inner bore, the annular element received within the first inner bore and comprising an outer surface having a non-circular cross-sectional profile. The clamping device can be movable between a release state in which the second inner bore has a first diameter, and a clamped state in which the second inner bore has a second diameter less than the first diameter.

Abstract: A valved conduit including a bioprosthetic aortic heart valve connected to a tubular conduit graft forming an ascending aorta. The conduit graft may attach to the heart valve in a manner that facilitates a redo operation in which the valve is replaced with another valve. A sewing ring may be pre-attached to the inflow end of the graft, and then the valve connected to a delivery holder advanced into the graft and secured to the sewing ring. Dry bioprosthetic valves coupled with conduit grafts sealed with a bioresorbable medium can be stored with the delivery holder.
