The MyoCath is a disposable needle injection catheter used for the delivery of biologic solutions to a targeted treatment site within the myocardium, the inner wall of the heart. It provides for multiple injections to a pre-determined needle insertion depth with a single core needle of 25 gauge diameter that can be advanced and retracted from the tip of the catheter. The MyoCath is intended for use with commercially available Becton-Dickinson 1 milliliter and 3 milliliter syringes. Although we hope to prove that MyoCell can be administered with a variety of different catheters, MyoCath has been specifically designed to be used for the delivery of MyoCell and has been used as the delivery mechanism in the majority of our clinical trials to date.
