There is provided an introducer system for percutaneously delivering a first and a second medical device to a patient. The system may comprise an introducer sheath having a longitudinal axis and a lumen formed therein. The system may also comprise a bifurcated hub coupled to a proximal end of the sheath. The hub may comprise a first arm having a first lumen and a first hemostasis valve for the passage of the first medical device. The hub may also comprise a second arm coupled to the first arm and having a second lumen and a second hemostasis valve for the passage of the second medical device. Further, the hub may comprise a connection port such that the first lumen and the second lumen are in communication with the lumen of the introducer sheath for the passage of at least one of the first and second medical devices through the introducer sheath for delivery to the patient.

Bifurcated hub

An expandable introducer sheath with an interlock dilator. The present technology provides an expandable sheath with a step feature inside its distal opening, and a dilator with an interlock that includes a catch surface configured to engage with the step feature and resist further relative movement so that the body of the dilator is prevented from exiting the distal end of the expandable sheath. This interlocking engagement may allow the dilator to be used to extend and maintain tension on the expandable sheath during insertion into a patient, and then to be retracted from the expandable sheath by pulling the dilator in the opposite direction. The present technology also provides a dilator hub with a spring mechanism configured to achieve and maintain a desired tension on the expandable sheath and to prevent overextension of the expandable sheath when the dilator is being inserted into the expandable sheath.
