VALVE FOR DILATOR AND SHEATH ASSEMBLY

摘要

A sheath assembly (10) includes an elongated hollow sheath body (44) having a proximal body end (41), a distal body end (43), and a longitudinal axis extending between the proximal body end and the distal body end. A sheath hub (50) is fixedly connected to the proximal body end and includes a hub proximal end and a hub distal end with a through passage extending from the hub distal end to the hub proximal end and in communication with the hollow sheath body. The sheath hub further defining a valve seat proximate the hub proximal end. A valve (80) is seated in the valve seat and includes a valve body with a bisecting slot extending into a proximal surface of the valve body and terminating at a depth less than the thickness of the valve body such that the remaining portion of the valve body distally of the slot defines a bridge extending between opposed halves of the valve body such that a distal surface of the valve body is substantially continuous, the valve extending across and sealing the through passage.
