摘要： An expandable, bistable open cell design incorporates the following features: a first relatively stiff portion (152) having first and second ends and a first relatively flexible portion (154) connected to the first and second ends of the first relatively stiff portion, the first relatively stiff portion and the first relatively flexible portion substantially surrounding a first open area (156) of the stent structure; a second relatively stiff portion (158) having first and second ends and a second relatively flexible portion (160) connected to the first and second ends of the first relatively stiff portion, the first relatively stiff portion and the first relatively flexible portion substantially surrounding a second open area (162) of the stent structure; and an opening (110) formed through the first relatively stiff portion and the second relatively flexible portion such that the opening connects the first and second open areas, thereby creating first and second intermediate ends (152a, 152b) of the first relatively stiff portion and first and second intermediate ends (160a, 160b) of the second relatively flexible portion. The first intermediate end (152a) of the relatively stiff portion is connected to the first intermediate end (160a) of the relatively flexible portion so as to create a first inward apex (170), the second intermediate end (152b) of the relatively stiff portion is connected to the second intermediate end (160b) of the relatively flexible portion so as to create a second inward apex (172), and the stent structure is configured such that, in a collapsed configuration, the first inward apex (170) is in contact with the second inward apex (172) and, in an expanded configuration, the first inward apex is biased to move in a first circumferential direction and the second inward apex is biased to move in a second circumferential direction that is different than the first circumferential direction.

摘要： A stent may include a connector having a first portion, a second portion, and a third portion positioned between the first and second portions. The connector may be configured to interconnect axially adjacent stent segments. The connector may be further configured such that the third portion severs in response to a threshold amount of axial force, axial foreshortening, and/or cyclic loading or fatigue, in order to predispose the severance of one or more pre-configured connectors in a controlled manner to minimize any potential harm to the surrounding vasculature of a patient.

摘要： A system used in a blood vessel when an interventional procedure is being performed in a stenosed or occluded region, which is capable of enabling an expandable cage assembly therein, adapted to filter the blood in a blood vessel, to be expandable, so as to capture any embolic material that may be created and released into the bloodstream during the interventional procedure. The system includes a catheter which is positionable in a blood vessel at the interventional procedure site. The system further includes an expandable cage assembly, which is expandable and which may be deployed in the blood vessel distal to the interventional procedure site, which includes a plurality of struts, adapted to be expandable from unexpanded condition thereof, wherein each of the plurality of struts includes an element for varying the stiffness along the length thereof, for enabling the expandable cage assembly to be expandable, portions thereof which are in contact in the unexpanded condition, wherein the expandable cage assembly is capable of expanding, while preventing the unexpanded in contact portions thereof from sticking together during expansion and deployment thereof.
