How it works
SĀPH is a closure device designed to achieve hemostasis after transradial procedures—without collapsing the artery. Here’s how it works:
SĀPH: Align notch with sheath to “keel” is directly over the hole in artery.
SĀPH is designed to apply controlled negative pressure (a gentle vacuum) to draw the arterial puncture site towards a soft, external seal.
Syringe is removed and valve in the tubing is designed to hold the negative pressure. Device is very comfortable and is removed before discharge.
Mechanism of action: gentle suction, not compression
SĀPH applies controlled negative pressure (a gentle vacuum) to draw the arterial puncture site toward a soft, external seal.
Unlike tourniquet-style bands that collapse the artery, SĀPH is designed to preserve blood flow while sealing the puncture site.
SAPH is designed to allow the vessel to remain patent as the arteriotomy is gently approximated to the subcutaneous tissue, allowing intrinsic blood pressure and clotting factors to facilitate natural healing.
Simplicity that reduces staff time
Designed for fewer nurse adjustments required
May reduce compression titration; patency assessment per site protocol
Designed for consistent setup and a more efficient post-procedure workflow
Patient and clinical advantages
Designed to:
reduce pressure-related pain and discomfort
preserve arterial flow to help prevent RAO
minimize complication rates and the need for re-intervention
be completely topical—no sutures, implants, or subdermal components
Clinical data on file
100% acute hemostasis; 0% RAO observed (n=14–17).
A prospective 50-patient study is ongoing.
Patent flow preserved
SĀPH maintains radial artery patency by eliminating circumferential compression—supporting natural sealing without flow compromise.
Designed to solve what others don’t
Engineered to overcome the limitations of current closure devices with a novel, non-occlusive, fully external design.
Ongoing clinical trials
50-patient study to support workflow efficiency, efficacy, safety, comfort, and success rates
