Abstract
A system for enabling the insertion and removal of an embolic protection device, for capturing and retaining embolic debris which may be created during the performance of a therapeutic interventional procedure in a stenosed or occluded region of a blood vessel. The system, in an embodiment thereof, enables the device to be compressed for insertion thereof through a patient'"'"'s vasculature so as to cross the stenosis in a low profile, and to enable release of compression thereof for expansion and deployment of the device at a location distal to the interventional procedure site.

27. A system for capturing embolic material in a body vessel, comprising:
-
a guide wire; a filter device on the guide wire, the filter device having an interior and an exterior and being movable between a compressed delivery position and a deployed position; a compressing element located in the interior of the filter device for compressing and maintaining the filter device in the compressed delivery position, the compressing element being removably connected to the filter device and adapted to disengage from the filter device to move the filter device into the deployed position; and a delivery enabling element coupled to the filter device and adapted to disengage the compressing element from its connection with the filter device to move the filter device into the deployed position. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)

42. A method for capturing embolic material which may be released into a body vessel during an interventional procedure by using a system including a filter device having an interior and an exterior and a compressing element located in the interior of the filter device for compressing and maintaining the device in a compressed delivery position, the compressing element being removably connected to filter device and adapted to disengage from the filter device to move the filter device into a deployed position and a delivery enabling element coupled to the filter device and adapted to disengage the compressing element from its connection with the filter device to move the filter device into the deployed position, the method comprising:
-
compressing a filter device by engaging the compressing element with the filter device; advancing a guide wire into a region of interest within the body vessel; delivering the compressed filter device along the guide wire using the delivery enabling element to the location in the patient'"'"'s vasculature distal to the interventional procedure site; and releasing the connection between the compressing element and filter device to move the filter device into the deployed position. - View Dependent Claims (43)

44. A method for capturing embolic material which may be released into a body vessel during an interventional procedure by using a system including a filter device having an interior and an exterior and a compressing element located in the interior of the filter device for compressing and maintaining the device in a compressed delivery position, the compressing element being removably connected to filter device and adapted to disengage from the filter device to move the filter device into a deployed position and a delivery enabling element coupled to the filter device and adapted to disengage the compressing element from its connection with the filter device to move the filter device into the deployed position, the method comprising:
-
compressing the filter device by engaging the compressing element with the filter device; advancing the guide wire and filter device into a region of interest within the body vessel; and releasing the connection between the compressing element and filter device to move the filter device into the deployed position. - View Dependent Claims (45, 46)
