摘要： A stent (10) formed from cannula and having flexible segments (11) and high hoop strength segments (12) alternating therealong. Axial tie bars (21, 22) interconnect the segments; minimal length reduction would occur upon expansion. In the high hoop strength segment (12), struts (16) are initially parallel in the unexpanded strut condition, while in the flexible segment (11), struts (14) extend from a respective bight (15) to converge at distal ends when unexpanded. In one embodiment, certain adjacent struts (16) of the hoop segment are spaced apart by a large gap (20) while others are spaced apart by a small gap (18). In another embodiment all the struts (16) of the hoop segment are spaced apart uniformly from each other (or from an axial tie bar) by a small gap (23), resulting in minimizing the occurrence of fatigue of high-stress sites upon expansion/contraction cycles from continuous pulsatile events.

摘要： An expandable endovascular stent comprises a flexible, tubular body (1) with a longitudinal axis, the wall of which is formed by interconnected, closed lattice cells (2) arranged with at least two cells adjacent to each other in the circumferential direction. Filament-shaped lattice material capable of transmitting compressive forces in the axial direction of the filament extends continuously from one lattice cell directly into the lattice cell following in the longitudinal direction. The stent can be expanded from a radially compressed state into a radially expanded state having a larger diameter. In the expanded state of the stent, the pressure transmitting lattice material in several of the lattice cells (2) forms a heart-like or arrowhead-like shape with at least two interconnected diverging, angle beta cell sides (5) positioned opposite to and interconnected with at least two mutually converging, angle alpha longer cell sides (3). For stability during expansion and compression of a self-expanding stent, the sum of the first angle alpha and the second angle beta should be in the range of 345 DEG to 360 DEG , preferably at 360 DEG to maintain a constant axial stent length.

摘要： A rapid exchange balloon catheter having a proximal end and a distal end, the catheter including a tubular metal shaft body extending from the proximal end along a majority of the total length and having an inflation lumen arranged therein, a plastics distal end portion bonded to the metal body in extension thereof, the distal end portion being provided with an inflation lumen in communication with a balloon, and a guide wire lumen, the guide wire lumen extending from a proximal side port to a distal end opening. To reduce the resistance to kinking, the metal body includes a transitional region having reduced stiffness at the position of bonding to the plastics distal end portion compared to a more proximal position along the metal body.
