1. A tissue compression device comprising:
- a base comprising a bottom surface and a top surface, wherein the base comprises a bladder orifice formed through the base from the bottom surface to the top surface;
retention structure attached to the base, the retention structure configured to retain the base over a selected location, wherein the bottom surface of the base is configured to face selected tissue at the selected location and wherein the top surface of the base is configured to face away from the selected tissue when the base is retained over the selected location;
a bladder operably attached to the base, wherein a lower surface of the bladder faces the selected tissue when the retention structure retains the base over the selected location, and wherein an upper surface of the bladder faces away from the lower surface of the bladder;
a ring indicator positioned above and in contact with the upper surface of the bladder, wherein the ring indicator is in a concave configuration, wherein a force exerted by the upper surface of the bladder on the ring indicator moves the ring indicator from the concave configuration to a convex configuration, and wherein an inner edge of the indicator ring is further away from the bottom surface of the base when the ring indicator is in the convex configuration than when the ring indicator is in the concave configuration;
wherein the tissue compression device defines a compression axis extending through the upper surface of the bladder, the bladder orifice in the base, and the lower surface of the bladder when the base is retained over the selected location by the retention structure.

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.

22. A method of monitoring pressure in a bladder of a tissue compression device, the method comprising:
-
restraining a tissue compression device over a selected location, wherein the tissue compression device comprises; a bladder comprising an upper surface located above and facing away from a top surface of a base of the tissue compression device; a ring indicator positioned above and in contact with the upper surface of the bladder, wherein the upper surface of the bladder is located between the ring indicator and the top surface of the bladder, and wherein the ring indicator is in a concave configuration; increasing fluid pressure within the bladder to cause the upper surface of the bladder to apply a force to the ring indicator sufficient to move the ring indicator from the concave configuration to a convex configuration, wherein an inner edge of the indicator ring is further away from the top surface of the base when the ring indicator is in the convex configuration than when the ring indicator is in the concave configuration. - View Dependent Claims (23, 24, 25, 26)
