How it works

SĀPH is a closure device that achieves hemostasis after transradial procedures—without collapsing the artery. Here’s how it works:

SĀPH: Align notch with sheath to guarantee “keel” is directly over the hole in artery.

SĀPH applies 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 holds 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 preserves blood flow while sealing the puncture site.

The vessel remains 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

  • Fewer nurse adjustments required

  • Reduced need for compression titration or ulnar artery occlusion

  • Designed to deliver consistent outcomes, minimal variability, 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% Hemostasis/0% RAO FIH Study

14-patient FIH study showed procedural success with no observed RAO.

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
