Vessel isolation device
First Claim
1. A vessel isolation device, comprising:
- a noninflatable expandable body, reversibly expandable from a low profile collapsed state to a generally hourglass-shaped expanded state, includinga 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, anda 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.

Abstract
The device utilizes a reversibly expandable body partially covered by a blood impermeable sleeve. The device has a low profile collapsed state for delivery and a expanded state for deployment. The impermeable sleeve extends from a proximal portion to a distal portion of the expandable body and generally follows the contour of the expandable body. When deployed, the device is configured in the expanded state and has a generally hourglass, or dumbbell shape. In the expanded state, portions of the sleeve adjacent to the proximal and distal portions are placed in apposition to a vessel wall and blood is free to flow through the expandable body via inlets and outlets provided in the proximal and distal portions. As a result, an isolated treatment space is created that surrounds the device between the vessel wall and the blood impermeable sleeve adjacent to the neck portion of the expandable body.

15. A vessel isolation system, 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; -
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; means for deploying the expandable body from the collapsed state to the expanded state; and at least one catheter tube having proximal and distal ends and access lumen extending therebetween, wherein the catheter tube distal end is coupled to an access port extending through the blood impermeable sleeve such that the access lumen is in fluid communication with the isolated treatment space, 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. - View Dependent Claims (16, 17, 18, 19, 20, 21)
