Axial lengthening thrombus capture system

摘要

Systems and methods can remove material of interest, including blood clots, from a body region, including but not limited to the circulatory system for the treatment of pulmonary embolism (PE), deep vein thrombosis (DVT), cerebrovascular embolism, and other vascular occlusions.

主权项

1. A clot capture system, comprising:
a first tubular member comprising a central lumen; a second tubular member; and a shape memory tubular body comprising a first end, a second end, and an axial length therebetween, the first end having an end opening, the second end attached to the second tubular member, wherein at least part of the shape memory tubular body is compressed within the central lumen of the first tubular member in a first delivery configuration, wherein the shape memory tubular body is transformable to a second configuration in which the first end is radially expanded while the second end and a majority of the shape memory tubular body remains radially compressed within the central lumen of the first tubular member and the second end is positioned proximal to the first end and the shape memory tubular body has a first expanded axial length, wherein the shape memory tubular body is transformable to a third configuration via movement of the first tubular member with respect to the second tubular member in which the shape memory tubular body has a second expanded axial length greater than the first expanded axial length, wherein a width of the shape memory tubular body along its second expanded axial length is substantially the same as a width of the shape memory tubular body along its first expanded axial length.
