1. A splittable sheath introducer, comprising:
- a splittable sheath;
a splittable hub disposed at a proximal end of the splittable sheath;
a valve included with the splittable hub; and
a valve actuator movable from a first position to a second position, the valve actuator opening the valve when in the second position, the valve actuator including a retaining member that enables the valve actuator to be retained by a portion of the splittable hub when the splittable sheath introducer is split apart.

Abstract
Tear-away sheath introducers for catheters, methods for making such introducers, and methods for using such introducers are described. A splittable sheath introducer may include a sheath, a hub disposed at a proximal end of the sheath, a valve included with the hub, and a valve actuator movable from a first position to a second position, the valve actuator opening the valve when in the second position. The valve actuator may include a retaining member that enables the valve actuator to be retained by a portion of the hub when the sheath introducer is split apart.

6. A method for inserting a catheter, comprising:
-
providing a splittable sheath introducer, the splittable sheath introducer including a splittable sheath, a splittable sheath hub disposed at a proximal end of the splittable sheath, the splittable sheath hub including a first retaining member, a valve disposed in the splittable sheath hub, and a valve actuator disposed in a cavity of the splittable sheath hub, the valve actuator including a second retaining member configured to mate with the first retaining member; inserting a distal portion of the splittable sheath into a portion of a body of a patient; moving the valve actuator from a first position to a second position so as to open the valve and mate the first retaining member with the second retaining member; inserting a catheter into the body of the patient through the open valve and the splittable sheath via a conduit defined by the valve actuator; and splitting the splittable sheath introducer such that the valve actuator remains attached to a portion of the splittable sheath hub after the splittable sheath introducer is split apart. - View Dependent Claims (7, 8)
