Abstract
The subject invention pertains to an elastic sheath, device, and methods for disrupting and/or removing occlusive material from lumens, particularly biological lumens, such as the vasculature, ureter, urethra, fallopian tubes, bile duct, intestines, and the like. The subject invention provides for effective disruption and removal of occlusive material, such as a thrombus, from the body lumen with minimal risk of injury to the lumen wall. Advantageously, the invention can be used to achieve a high degree of removal while minimizing the amount of occlusive material that is released into the body lumen. The subject invention further pertains to methods for disrupting and removing occlusive material from a biological lumen. In another aspect, the present invention concerns a device useful as an in vitro model of luminal occlusion and methods for using the device to test the efficacy of devices and methods for treating luminal occlusions.
