    摘要： A device for sealing a puncture opening in a wall of a blood vessel may include a base frame including a first bi-stable material having a first stable state corresponding to a delivery configuration of the base frame, in which the base frame is retracted to have a relatively smaller overall profile, and a second stable state corresponding to a deployed configuration of the base frame, in which the base frame is extended to have a relatively larger overall profile. The base frame is sized to engage an interior surface of the blood vessel wall when in the deployed configuration. A sealing section is coupled to the base frame and includes a second bi-stable material having a first stable state corresponding to an initial configuration of the sealing section, in which the sealing section permits fluid flow, and a second stable state corresponding to a barrier configuration of the sealing section, in which the sealing section prevents fluid flow. The sealing section in the barrier configuration is sized to block fluid flow through the puncture opening when the base frame is in the deployed configuration.

    摘要： An expandable stent for percutaneous procedures comprises a tubular structure disposed about a longitudinal axis and a plurality of fingers. The plurality of fingers, upon expansion of the stent, extends from the tubular structure about a second longitudinal axis which is angularly offset from the first longitudinal axis. At least one of the plurality of fingers has a length that is greater than that of the other fingers.

    摘要： Devices and methods for transferring forces down a catheter shaft while also maintaining an open fluid pathway are disclosed. In some of the designs, inner and outer members of the catheter interact, allowing improved transfer of forces down the catheter shaft. These designs also allow for maintenance of a fluid pathway along the length of the shaft, including at locations where the inner and outer members are interacting with one another. Structures are disclosed which extend at least a portion of the length of the shaft, allowing improved force transfer and resistance to kinking. Structures are also disclosed which specifically allow for inner and outer members to engage one another at at least one point along the shaft, improving the transfer of forces down the shaft.
