Patent ID: 7819841

Claim:
A vessel isolation device, comprising: a noninflatable expandable body, reversibly expandable from a low profile collapsed state to a generally hourglass-shaped expanded state, including a proximal portion having at least one inlet formed therein, a distal portion having at least one outlet formed therein, the outlet being in fluid communication with the inlet via a central lumen defined by the expandable body, and a neck portion disposed between the proximal and distal portions; and a blood impermeable sleeve disposed about the neck portion of the expandable body and at least a portion of the proximal and distal portions of the expandable body, the sleeve being reversibly expandable with the expandable body from the collapsed state to the expanded state, wherein the sleeve is adapted to be placed in continuous circumferential contact with a vessel wall adjacent to the proximal portion and the distal portion when the expandable body is in the expanded state, thereby creating an isolated treatment space; and wherein the isolation device further comprises at least one catheter tube having proximal and distal ends and an access lumen extending therebetween, wherein the catheter tube distal end is coupled to the blood impermeable sleeve such that the access lumen is in fluid communication with the isolated treatment space at an access port extending through the impermeable sleeve, the at least one catheter tube extending from the access port into the central lumen and protruding from the proximal portion of the expandable body adjacent the at least one inlet.
