摘要： A barb for anchoring an implantable medical device to a body vessel comprises a thin-walled body portion for engagement with a structural element of an implantable medical device and a penetrating element extending from the body portion. The body portion has a longitudinal axis. The penetrating element includes a tip portion for anchoring into tissue and a base portion between the tip portion and the body portion. In a deployed configuration of the barb, the base portion curves away from the longitudinal axis at a first curvature and the tip portion curves toward the longitudinal axis at a second curvature which is opposite in sign from the first.

摘要： A variable curvature stent limb (100) is disclosed. The stent limb has an S-shape enabling it to be compressed into a substantially flat condition. A stent (195) formed from a plurality of these variable curvature stent limbs (100) IS highly compressible, such that it is compatible with a low-profile delivery device. This stent (100) may be useful over a wider range of body vessel diameters and may possess a greater fatigue life, since this stent may provide a more controlled constant radial force.

摘要： A device for delivering and deploying a radially expandable prosthesis is disclosed and comprises a proximal prosthesis release mechanism having a first resistance and a distal prosthesis release mechanism having a second resistance. The device further comprises an actuation mechanism for actuating the distal and proximal release mechanisms in a single coordinated movement and a biasing compensator for regulating the relationship between the first resistance and the second resistance. Additional aspects of the invention include devices and methods for delivering and deploying a radially expandable prosthesis.

摘要： A strut, or beam, is provided for intraluminal devices. Strain which is introduced into a stent or other intraluminal device is distributed more evenly along the length of the improved strut by maintaining a substantially constant strain level along the length of an end portion. This may increase fatigue life or improve the performance of devices using the improved strut. The strain along the length of the end portion may be maintained substantially constant by varying a section property of the strut, including the width, thickness, cross-sectional area, material property or other characteristic of the end portion.
