In vivo filter assembly
First Claim
1. An assembly for filtering debris flowing in an in vivo fluid stream, the assembly comprising:
- i) at least one balloon configured to volumetrically expand and, during at least a portion of said expansion, operatively connect with a filter, and to contract following said expansion;
ii) a filter configured to operatively connect with said at least one balloon during at least a portion of said volumetric expansion of said at least one balloon, such that said filter expands during said operative connection in order to filter debris from a fluid flowing in a fluid stream within which said expanded filter is disposed,wherein said filter includes;
a) a distal portion;
b) a proximal portion;
c) an opening to said filter associated with said proximal portion; and
d) wherein at least one cord guide channel circumferentially encircling at least a portion said proximal portion and comprises two cord channels located substantially on the same cross-sectional plane of the filter, and wherein at least two cords are disposed in each of the cord channels to connect to the filter.

Abstract
Disclosed is an assembly for filtering debris flowing in an in vivo fluid stream, the assembly comprising at least one balloon configured to volumetrically expand and, during at least a portion of the expansion, operatively connect with a filter, and to contract following the expansion. The assembly further comprising a filter configured to operatively connect with the at least one balloon during at least a portion of the volumetric expansion of the at least one balloon, such that the filter expands during the operative connection in order to filter debris from a fluid flowing in a fluid stream within which the expanded filter is disposed.

20. An assembly for filtering debris flowing in an in vivo fluid stream, the assembly comprising:
-
i) at least one balloon configured to volumetrically expand and to contract following said expansion; and ii) a filter comprising a material having tissue connective properties for a portion of luminal tissue associated with an in vivo fluid stream, said filter positioned to operatively connect with said at least one balloon during at least a portion of said expansion and removably connect to least a portion of said tissue and remain so connected during said contraction of said at least one balloon, wherein said filter includes; a) a distal portion; b) a proximal portion; c) an opening to said filter associated with said proximal portion; and d) wherein at least one cord guide channel circumferentially encircling at least a portion said proximal portion and comprises two cord channels located substantially on the same cross-sectional plane of the filter, and wherein at least two cords are disposed in each of the cord channels to connect to the filter.
