Принадлежит: Individual

A balloon or self expandable endoprosthesis formed of a single or multiple joined stent sections. Each section has a node and strut structure extending throughout in order to uncouple expansion forces of the stent to hold a blood vessel outward from crush forces that resist the formation of an oval shape during crush deformation. The hinge can bend in the direction of a uniformly curved surface of the stent but not in the radial direction. The strut can bend in the radial direction but not in the uniformly curved surface of the stent. The widths, lengths, and radial dimensions of the hinges and struts provide a balloon-expandable hinge stent that is non-crushable. For a self-expanding stent the hinge and strut dimensions provide expansion forces that are controlled independently from crush forces. Expansion properties are determined by the hinge dimensions and crush properties are determined independently by strut dimensions.

A stentless support structure capable of being at least partly assembled in situ. The support structure comprises a braided tube that is very flexible and, when elongated, becomes very long and very small in diameter, thereby being capable of placement within a small diameter catheter. The support structure is preferably constructed of one or more thin strands of a super-elastic or shape memory material such as Nitinol. When released from the catheter, the support structure folds itself into a longitudinally compact configuration. The support structure thus gains significant strength as the number of folds increase. This radial strength obviates the need for a support stent. The support structure may include attachment points for a prosthetic valve.

Номер: US20120290069A1
Автор: David Ernest Hartley, Krasnodar Ivancev, Piotr Miroslaw Kasprzak
Принадлежит: Cook Medical Technologies LLC

A stent graft defining a main lumen bounded by a wall of graft material is disclosed. The stent graft has a valve portion between proximal and distal portions. The valve portion is formed by a wall portion having a part-circumferential double layer portion comprising an inner underlap portion and an outer overlap portion, the double layer portion forming a passageway parallel to the main lumen. The passageway has an entrance mouth and an exit mouth. The passageway has an open condition where the underlap and overlap portions are spaced apart to form a vent lumen. The wall portion is broken by a narrow cut. The cut is openable by relative radial movement between its edges. This allows re-perfusion of an aneurism and perfusion of blood from within the lumen out towards blood vessels such as intercostals and can assist in minimising the chance of paraplegia.
