This is a prospective, multicenter study intended to provide supportive clinical information on the use of the SAPH device to achieve radial artery patent hemostasis after a transradial procedure.

This is a prospective, multicenter, nonrandomized, single-cohort, interventional clinical study intended to provide supportive clinical information to the nonclinical characterization and performance data required for demonstration of substantial equivalence to marketed devices. The study will assess clinical use elements such as ease of use, patient comfort, as well as safety and effectiveness.
