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,
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.
What is claimed: 1. 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 including an engageable element and an exterior and being movable between a compressed delivery position and a deployed pos
What is claimed: 1. 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 including an engageable element 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 maintaining the filter device in the compressed delivery position, the compressing element including a slot which receives the engageable element and is 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 adapted to disengage the compressing element from its connection with the engageable element of the filter device to allow the filter device to move into the deployed position. 2. 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 including an engageable element 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 maintaining the filter device in the compressed delivery position, the compressing element having a structure which receives the engageable element so that the compressing element is 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, wherein the filter device is slidably disposed on the guide wire and the delivery enabling element is adapted to move the filter device along the length of the guide wire. 3. The system of claim 2, wherein the delivery enabling element is removably coupled to the filter device. 4. The system of claim 2, wherein the filter device includes a locking mechanism for locking the filter device to the guide wire. 5. The system of claim 4, wherein the delivery enabling element maintains the locking mechanism in an unlocked position and is adapted to move the locking mechanism into a locked position on the guide wire. 6. The system of claim 5, wherein the locking mechanism is a deflectable tab. 7. The system of claim 2, wherein the delivery enabling element has a distal end coupled to the filter device and a proximal portion which can be manipulated to disengage the compressing element from its connection with the filter device. 8. The system of claim 2, wherein the delivery enabling element includes an outer member co-axially disposed over an inner member, the inner member being in contact with the compressing element to maintain the compressing element connected to the filter device to maintain the filter device in the compressed position. 9. The system of claim 8, wherein the filter device includes a locking mechanism for locking the filter device to the guide wire and the inner member of the delivery enabling element maintains the locking mechanism in an unlocked position and is adapted to move the locking mechanism into a locked position on the guide wire. 10. The system of claim 8, wherein the inner member of the delivery enabling element includes a lumen for receiving the guide wire. 11. The system of claim 2, wherein the delivery enabling element includes a lumen for receiving the guide wire. 12. The system of claim 2, wherein the filter device includes a self-expanding cage and a filter element attached to the self-expanding cage. 13. The system of claim 2, wherein the compressing element remains within the interior of the filter device after the filter device is placed in the deployed position. 14. The system of claim 13, wherein the compressing element is integral with the delivery enabling element. 15. The system of claim 2, wherein the guide wire includes a stop member mounted thereto which abuts against the compressing element to allow the compressing element to disengage from the filter device. 16. 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 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, wherein the filter device is slidably disposed on the guide wire and the delivery enabling element is adapted to move the filter device along the length of the guide wire, wherein the delivery enabling element includes an outer member co-axially disposed over an inner member, the inner member being in contact with the compressing element to maintain the compressing element connected to the filter device to maintain the filter device in the compressed position and the contact between the inner member and compressing element is removed to allow the filter device to move into the deployed position. 17. 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 including an engageable element 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 having a structure which receives the engageable element so that the compressing element is 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 engageable element located in the interior of the filter device; advancing a guide wire into a region of interest within the body vessel; delivering the compressed filter device by moving it along the length of 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 the engageable element to move the filter device into the deployed position. 18.
