Embodiment Construction

[0041] Percutaneous coronary diagnostic and interventional procedures can be performed with a catheter introduced into the radial artery. The sheath with the hemostatic valve is inserted through the opening or access point, into the radial artery. A preformed catheter can then be passed through the sheath to the ostium of the relevant coronary artery or other location in the patient's body. The catheter enables the delivery of instruments and fluids such as contrast media, angioplasty wires, balloons and stents. During a procedure, maintaining hemostasis at the point of entry is desirable to reduce blood loss to the patient, achieve desired performance during the procedure, and limit the risk of infection. After the procedure is complete, the sheath and catheter are removed and the flow of blood through the point of entry is stopped.

[0042] As with any arterial puncture, achieving hemostasis during and after the procedure can be challenging. During the procedure, blood ma...

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.

Description

technical field [0001] The present disclosure relates to a radial artery compression device. More specifically, the present disclosure relates to a radial artery compression device configured to provide adjustable levels of compression pressure on the radial artery to achieve hemostasis at or in the region of a vascular access point. Background technique [0002] Advances in medicine have yielded the ability to diagnose and treat coronary artery disease using vascular delivery devices and techniques. One advantage of coronary procedures using vascular delivery is that a physician can gain access to a desired location within a patient's body without the use of general anesthetics or the need for highly invasive procedures. During typical procedures, a sheath with a hemostatic valve is used at the vessel access point to access peripheral arteries using local anesthetic. A preformed catheter is then introduced through the sheath into the patient's vasculature. The catheter i...
