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.

Tissue compression devices having a tension limiting strap retainer and methods of using the same. The tissue compression devices described herein may include a strap retainer that is attached to a base by an elastic member that is configured to draw the strap retainer towards the base. The tissue compression devices described herein may also include a tension indicator that extends between the base of the tissue compression device and strap retainer. The tension indicator may be configured to limit the travel distance of the strap retainer away from the base in response to forces acting on the strap retainer. The tension indicator may also provide visual feedback to a user of the tension force in a strap to attach the tissue compression device to a patient.

A guide catheter assembly includes a dilator and a guide catheter. The dilator includes a dilator lumen extending from a distal opening at a distal end to a proximal opening at a proximal end, and a side exit port proximal of the distal opening and in communication with the dilator lumen. The guide catheter includes a proximal end, a distal end, and a guide lumen extending therebetween. The dilator and the guide lumen are sized such that the dilator can pass through the guide lumen. The dilator and the guide catheter are sized such that with the proximal end of the dilator generally aligned along an axis with the proximal end of the guide catheter, the distal end of the dilator extends distally past the distal end of the guide catheter and the side exit port is disposed distal of the distal end of the guide catheter.

Tissue compression devices including a multi-chamber bladder that is retained within the tissue compression device, with the multi-chamber bladder being positioned in a bladder orifice in a base of a compression device body. The multi-chamber bladder includes at least one upper chamber located above the base and at least one lower chamber located below the base. The lower chamber is located between the base and a selected location on a patient when the compression device is positioned over selected tissue such as, e.g., a radial artery, as described herein.
