Patent ID: 8657850

Claim:
A radial artery compression device, the radial artery compression device adapted to allow a user to provide varying degrees of pressurization against a patient's radial artery to maintain a desired degree of hemostasis at a percutaneous access site, the radial artery compression device comprising: a knob configured to be grasped by a user and rotated; a body configured to engage the knob such that the knob can be rotated relative to the body while remaining secured at a fixed position with respect to the body; a compression pad comprising; a first substantially planar contact surface, a second substantially planar contact surface, a curved step disposed between the first and second contact surfaces, the curved step comprising a single continuous radius extending from the first contact to the second contact surface, the radius of the curved step configured to contour to a radius of a device configured for insertion into the radial artery, and a notch in the perimeter of the compression pad, the notch directly intersecting the first contact surface, the second contact surface, and the radius of the curved step; wherein the notch is in communication with the curved step such that the notch is configured to at least partially surround a device configured for insertion into the radial artery, and wherein the first and second contact surfaces are not coplanar; a threaded shaft formed of rigid material and disposed through the body, the threaded shaft being positioned between the knob and the compression pad, the threaded shaft configured to move the compression pad with respect to the body as the knob is rotated relative to the body; and a band to secure the body to the underside of a wrist of a patient in the area of the radial artery, such that the compression pad can be positioned adjacent the wrist of the patient wherein the user rotates the knob to selectively move the compression pad between a first position and at least a second position to provide varying degrees of pressurization to the wrist of a patient, wherein when the compression pad is in a first position, the compression pad is positioned adjacent the body and applies a lesser degree of pressurization against the wrist of the patient and when the compression pad is in the second position, the compression pad is positioned a given amount of displacement from the body and provides a greater amount of pressurization against the patient's wrist; wherein the knob comprises threads to engage threads on the threaded shaft such that rotation of the knob moves the shaft with respect to the body.
