Abstract

A new extended hemostasis valve for sheaths is presented, with minimized stick-slip behavior to beused in (heart) catheterization procedures during long interventions (3-6 hours). The inventedextension to this existing sheath bypasses the silicone rubber sealing (hemostasis valve) and replaces itwith a dedicated seal with the two functions separated: (1) sealing around the catheter on use and (2)closing the sheath when the catheter is removed (valve function).Measurements have been performed on a current and the invented seal, showing that the axial frictionforce reduces with a factor 6.4: from 1.4 to 0.22 N.
