Methods, systems, and devices for deploying an embolic protection filter
First Claim
1. A restraining mechanism configured to prevent a plurality of struts of a filter device from extending outwardly prior to deploying a filter of the filter device, the restraining mechanism comprising:
- (a) a sleeve disposable substantially at a distal end of the filter device, said sleeve being attached to least one of the plurality of struts of the filter and applies a restraining force to the plurality of struts of the filter device to prevent the plurality of struts from extending outwardly; and
(b) at least one actuating member at least partially interwoven with said sleeve, said at least one actuating member releasing said restraining force of said sleeve so that the plurality of struts of the filter device extend outwardly as said at least one actuating member is moved in a proximal direction.

Abstract
A filter device is adapted to function as a guidewire, an exchange guidewire, and provide embolic protection during a procedure. The filter device includes a filter assembly that is either integral with or coupled to a guide member. The filter assembly includes a plurality of struts that expand outwardly to deploy a filter that collects or captures material flowing along the blood vessel within which the filter device is deployed. The plurality of struts are constrained by a restraining member or mechanism that prevents the plurality of struts from expanding or extending outwardly to deploy the filter. Cooperating with the restraining member or mechanism is an actuating assembly that is adapted to release the restraining member or mechanism and enable the filter to be deployed from the guide member. A capture catheter is cooperates with the filter device and substantially surrounds the filter during removal of the filter device.

16. A restraining mechanism configured to prevent a plurality of struts of a filter device from extending outwardly prior to deploying a filter of the filter device, the restraining mechanism comprising:
-
(a) means for applying a restraining force to the plurality of struts of the filter device to prevent the plurality of struts from extending outwardly, said means for apply the restraining force being attached to at least one of the plurality of struts of the filter; and
(b) at least one actuating member at least partially interwoven with said means for applying the restraining force, said at least one actuating member releasing said restraining force of said means for applying said restraining force and enabling the plurality of struts of the filter device to extend outwardly to deploy the filter as said at least one actuating member moves in a proximal direction. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A method for releasing a plurality of struts of a filter device during a procedure, comprising:
-
(a) positioning a filter device in a vasculature of a patient, distal of a portion of a blood vessel to be accessed during a procedure, to collect emboli, the filter device comprising;
(i) a guide member comprising a distal end;
(ii) a plurality of struts cooperating with said distal end of said guide member;
(iii) a filter coupled to said guide member; and
(iv) a restraining member attached to at least one of said plurality of struts to prevent said plurality of struts from extending outwardly; and
(b) actuating an actuating member at least partially interwoven through at least a portion of said restraining member, wherein actuating said actuating member in a proximal direction releases said plurality of struts to deploy said filter, wherein following collecting emboli, said filter device and said actuating member are removed from the blood vessel. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42)

43. A restraining mechanism configured to prevent a plurality of struts of a filter device from extending outwardly prior to deploying a filter of the filter device that is attached to the plurality of struts, the restraining mechanism comprising:
-
(a) a sleeve disposable substantially at a distal end of the filter device to surround the plurality of struts of the filter device and apply a restraining force to the plurality of struts of the filter device to prevent the plurality of struts from extending outwardly, said sleeve at least partially attached to at least one of the plurality of struts and having a proximal end, a distal end, and one or more preferential separation regions extending from said distal end toward said proximal end, and (b) at least one actuating member at least partially interwoven with said sleeve, said at least one actuating member releasing said restraining force of said sleeve so that the plurality of struts of the filter device extend outwardly as said at least one actuating member is moved in a proximal direction to preferentially separate said sleeve, while at least a portion of said sleeve remains attached to at least one of the plurality of struts of the filter device. - View Dependent Claims (44, 45, 46)
