The TIE device is a tourniquet-style surgical instrument used to control the target location of knot seating during precise suture knot tying and delivery applications. The COLLAR device is a flexible surgical retractor designed to retract valve leaflet tissue when inserted within the valve annulus. The device consists of a main body component which extends laterally to become the retraction wings. The distal tips of the retraction wings are bifurcated for additional tissue traction. The posterior aspect of the device has a stiffening rib along the superior border and a stabilization flange along the inferior border. The COLLAR device is available in 2 sizes (small and large) which are packaged together in a disposable set with the TIE device.
