1. A device for exsanguinating a portion of an extremity, the device comprising:
- i) a torus having a variable circumferential diameter, said torus configured to encircle an extremity portion and apply exsanguination pressure thereto wherein said torus comprises an elastic material and a variably extendable tension band contained by said elastic material; and
ii) a transducer operatively associated with said torus, wherein said transducer, comprises the at least one variably extendable tension band substantially contained within a cross sectional portion of said torus;
said transducer, while said torus is encircling said extremity portion, being configured to control at least one of;
a diameter of said variable circumferential diameter;
a tension in said tension band within said torus; and
a pressure applied by said torus;
wherein said torus is adjusted actively by said transducer and also passively as said elastic material is compressed against said extremity portion; and
wherein, said torus includes at least one wheel located around a cross sectional section of an annular portion of said torus, said at least one wheel configured to roll as said torus moves linearly along said extremity portion.

Abstract
Disclosed is a device for exsanguinating a portion of an extremity, the device comprising a torus having a variable circumferential diameter, the torus configured to encircle an extremity portion and apply exsanguination pressure thereto, and a transducer operatively associated with the torus, the transducer, while the torus is encircling the extremity portion, being configured to control at least one of a diameter of the variable circumferential diameter, a tension in the torus and a pressure applied by the torus.

20. A method for exsanguinating an extremity portion, the method comprising:
-
i) providing a torus configured to encircle a cross sectional annulus of an extremity portion;
wherein said torus comprises;an elastic material; and one variable circumferential diameter adjuster, having a variable coefficient of tension comprising at least one of; a variable length band; and a variably inflatable ballast; substantially contained within a cross sectional portion of said torus, configured to apply substantially constant exsanguinating pressure to said extremity portion; ii) moving said torus along said extremity portion; and iii) applying said substantially constant exsanguinating pressure with said torus to said extremity during said moving as said elastic material is compressed against said extremity and by increasing the tension in said circumferential diameter adjuster to decrease the diameter of said torus as it is moved over narrower cross-sections of said extremity and decreasing the tension in said circumferential diameter adjuster to increase the diameter of said torus as it is moved over wider cross-sections of said extremity. - View Dependent Claims (21, 22)
