ABSTRACT:
A hemostasis valve for a catheter such as a catheter sheath introducer comprises an elastomeric partition extending across an aperture in a hub carried by a catheter. The partition defines an annular, peripheral area which is secured to the hub. The partition further defines a second area positioned radially inwardly from the peripheral area. The second area is of substantially less thickness than the peripheral area. The partition further defines a central area positioned radially inwardly from the second area, the central area being of substantially greater thickness than the second area, and defining a slit therethrough to permit passage of the elongated member.
