1. A method for exsanguinating a portion of an extremity, the method comprising:
- i) encircling a cross sectional portion of an extremity with at least one exsanguinating pressure inducer;
ii) moving one or both of a pressure produced at a pressure application point by said at least one exsanguinating pressure inducer and a portion of said extremity with respect to each other;
iii) inducing an exsanguinating pressure on the portion of the extremity to which pressure is applied during said moving; and
iv) controlling said exsanguinating pressure to remain within an exsanguinating range of pressure.

Abstract
Disclosed is a method for exsanguinating a portion of an extremity. The method comprises, encircling a cross sectional portion of an extremity with at least one exsanguinating pressure inducer, moving one or both of a pressure produced at a pressure application point by the at least one exsanguinating pressure inducer and a portion of the extremity with respect to each other, inducing an exsanguinating pressure on the portion of the extremity to which pressure is applied during the moving, and controlling the exsanguinating pressure to remain within an exsanguinating range of pressure.
