How It Works

How the Input Introducer Sheath Works

Coronary catheterization is a minimally invasive procedure to access the coronary circulation using a catheter. The procedure uses a special dye that helps visualize the blood flow through the heart.

The procedure begins with access to the femoral artery through the groin.

A needle is inserted through the skin into the femoral artery. The needle is withdrawn until a flash of blood appears.

The sheath is introduced with the accompanying dilator.

Introducing the sheath

The dilator is removed. The sheath is left behind in the blood vessel holding the tract open and protecting the vessel from trauma.

Input Introducer Sheaths

Medtronic offers a comprehensive range of access products for the diagnostic angiogram. Designed for easy insertion and for patient comfort, Input^® Introducer Sheaths are offered in two brands – Input TS and Input PS.

Input TS is Medtronic's FEP sheath with silicone coating to enhance the low drag coefficient of the sheath and dilator system. The polyethylene dilator with silicone coating and gradual taper reduces force during insertion.

Input PS is based on the Input TS platform. The Input PS sheath includes a proprietary HydroPel coating that reduces insertion force. The Hydrophilic coating activates on contact with fluids to produce a smooth, slick surface. The Pebax material shaft adds the right balance of strength and flexibility for atraumatic insertion into tortuous anatomies.

Product features of Input Introducer Sheaths include:

• Sit-Up Capability: Kink-resistant system provides 60 degree sit-up comfort for patients with an obturator in place.
• Locking Hub: Threaded dilator-to-hub interlock prevents dilator backout during insertion, and secure attachment of the sterile sleeve.
• Enhanced Tip Geometry: Advanced radiofrequency shaping technology creates a long, continuously smooth taper, for minimum resistance during insertions.
• Large Internal Geometry: Input TS's exceptionally large internal geometries facilitate hemodynamic monitoring and fluid administration.
