Abstract
An angioplasty device and particle trap for use in medical, veterinary, non-medical or industrial applications where removal of an obstruction from a small diameter vessel or vessel-like structure could produce particles, which, if allowed to remain in the vessel, could cause undesirable complications and results. One angioplasty device embodiment comprises a catheter for insertion into a vessel-like structure and a trap operably connected to the catheter and to a rotatable member. Rotating the rotatable member relative to the catheter actuates the trap. One particle trap embodiment comprises a rotatable member that actuates a flexible strut between an arcuately expanded position and a helically twisted position, and a membrane operably connected to the flexible strut.
