Vascular and aortic connectors with telescoping sheath

Abstract

A vascular connector deployment tool may include a handle, an elongated mandrel extending distally from the handle, a vascular connector disposed coaxially about the mandrel, a retractable sheath assembly including an outer sheath telescopically deployed over an inner sheath and an actuator on the handle that is configured to selectively retract the outer sheath and the inner sheath relative to the mandrel. The sheath assembly is configured to constrain the vascular connector against the mandrel in an insertion profile. A distal transition between the outer sheath and the inner sheath visually indicates position of the vascular connector.
