RADIAL ARTERY COMPRESSION DEVICE
First Claim
1. 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;
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.

Abstract
A radial artery compression device configured to be releasably secured by a strap or band to the underside of a wrist of a patient and to provide adjustable and consistent compression pressure in the area of a radial artery access site to achieve hemostasis either during or after a medical procedure such as a percutaneous coronary procedure. The radial artery compression device includes a body configured to engage and secure a knob while allowing the knob to rotate with respect to the body. Rotation of the knob can cause a threaded shaft to move. The threaded shaft mechanically couples the knob to a disk-shaped compression pad. The compression pad can include one or more notches adapted to at least partially surround a sheath and/or a catheter inserted into the radial artery at the access site. The compression pad can also include a step on the surface to provide a desired amount of contour to a portion of a device within the radial artery during a procedure.

17. A method for achieving hemostasis at an access site of a radial artery of a patient, the method comprising:
-
providing a 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, a threaded shaft formed of rigid material and disposed through the body and 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 the patient in the area of the radial artery, such that the compression pad is positioned adjacent the wrist of the patient; securing the radial artery compression device to a wrist of the patient, the compression pad of the radial artery compression device positioned adjacent the access site of the radial artery of the patient; and rotating the knob relative to the body to increase compression pressure applied by the compression pad at the access site until hemostasis at the access site is achieved. - View Dependent Claims (18, 19)

20. A radial artery compression device, comprising:
-
means for rotating a plurality of threads, the rotating means configured to be grasped by a user and rotated; means for compressing a radial artery of a patient at an access site of the radial artery, the compressing means configured to be displaced longitudinally along an axis of rotation of the rotating means as the rotating means is rotated to adjust the level of compression pressure applied to the radial artery of the patient; means for supporting the rotating means and the compressing means, the supporting means configured to engage the rotating means such that the rotating means can be rotated relative to the supporting means while remaining secured at a fixed position with respect to the supporting means and the supporting means configured to receive the compressing means when the compressing means is displaced longitudinally toward the supporting means along the axis of rotation of the rotating means; and means for securing the supporting means to the underside of a wrist of a patient in the area of the radial artery, such that the compressing means is positioned adjacent the wrist of the patient. - View Dependent Claims (21, 22)
