Aortic great vessel protection
First Claim
1. A vessel protector system, comprising:
- an outer sheath;
an inner tube disposed within the outer sheath and moveable in a longitudinal direction relative to the outer sheath;
at least one protector having a body formed from filtering material and extending between a leading end thereof and a trailing end thereof, the trailing end being coupled to the inner tube, and the body being adapted to be received within the outer sheath thereby having a collapsed configuration spanning a first length from the leading end to the trailing end and further adapted to be discharged from the outer sheath thereby having an expanded configuration spanning a second length, the second length being greater than the first length; and
a snare coupled at one end thereof to the leading end of the body, and having a second end thereof passing through the interior of the outer sheath, wherein the snare is capable of pulling a portion of the at least one protector within the inner tube;
wherein the outer sheath is moveable between a first position receiving the at least one protector and a second position where the at least one protector is discharged therefrom.

Abstract
A vessel protector system includes an outer sheath, an inner tube disposed within the outer sheath and moveable in a longitudinal direction relative to the outer sheath and at least one protector coupled to the inner tube, each of the at least one protector having a body formed from a filtering material and extending between a leading end and trailing end coupled to the inner tube, the body having a collapsed configuration and an expanded configuration. A snare is coupled to the leading end of the body at one end, and having a second end passing through the interior of the outer sheath, whereby the exertion of a pulling force on the second end of the snare contracts the at least one protector.
