An over-the-wire 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 embodiment comprises a catheter (26) for insertion into a vessel like structure, the catheter having a catheter wall and a moveable member, a trap (38) operably connected to the catheter wall and to the moveable member, wherein relative motion between the catheter wall and the moveable member actuates the trap. The catheter in this embodiment defines a guidewire lumen adapted to slideably receive a guidewire (fig. 2). Some embodiments also include a selective coupling device.
