Technology description follows.

Medical Device for Vascular Dilation

A vascular dilator is commonly used in transcatheter cardiovascular intervention procedures. Commercially available vascular dilators have introducer sheaths with a finite thickness and mismatched diameter with the dilators. This causes uneven stretching of the trailing edge of the sheath and severe damage to the target vessels. This technology produces the specialized sheath with a shoulder that can be introduced percutaneously with an enhanced dilator into a broad range of diseased target vessels and chambers with reduced vascular injury. The shoulder helps to match the diameter of the introducer sheath so that there is a smooth transition between the dilator and the introducer sheath. The invention allows the dilator to be withdrawn in segments without disrupting the introducer sheath.Start Printed Page 14955

Development Stage: Reduces vascular injury while using large-bore introducer sheaths in interventional cardiac procedures:
