Abstract
An introducer assembly includes a valve having a first end and an opposite second end; a sheath fixedly secured to and extending axially from one of the first and second ends of the valve; a dilator extending through the valve and sheath; and a lock knob rotatable between locked and unlocked positions to releasably axially lock the tool relative to the sheath without causing corresponding rotation of the tool therewith.
Claims6
A method of assembling an introducer sheath assembly having a longitudinal axis defining an axial direction along the longitudinal axis, a transverse direction transverse to the longitudinal axis, and a rotational direction about the longitudinal axis, the introducer sheath assembly including a valve with an inner tube, an introducer sheath secured at an end of the valve, an introducer tool coaxially received in the introducer sheath, and a fitting secured to the introducer sheath, the method comprising:
- sliding an introducer tool into an introducer sheath in the axial direction until the fitting extends into the inner tube of the valve to form a fluid seal;
- and
- locking a locking mechanism of the introducer sheath assembly, including rotating a lock knob of the locking mechanism in the rotational direction without causing movement of the introducer tool in the axial direction and without causing movement of the introducer tool in the rotational direction, wherein locking the locking mechanism includes securing the lock knob to the fitting by rotating the lock knob.
