Abstract

Tissue compression devices having pressure indicators and methods of using the same. The tissue compression devices provide feedback to a user with respect to the pressure being applied to selected tissue at a selected location such as a radial artery to assist the user in applying the desired amount of pressure to the tissue (such as the pressure needed to achieve hemostasis at an access site). The pressure indication may be provided by a ring indicator that moves between two configurations (e.g., a concave configuration and a convex configuration), a bellow chamber in a housing, a bladder located below a bladder window, etc.
