ABSTRACT:
An improved percutaneous introducer device is provided that inhibits or prevents undesired shearing of the splittable sheath component of the device. The device includes an interference tab that extends between two wing portions which axially shear the splittable sheath component of the device upon application of an effective force thereto. The interference tab effectively blocks undesired shearing forces that may occur during manipulation of the device by medical personnel or the patient prior to and during placement of a catheter, guide wire or other device.
