Hydromer’s Hydrophilic Coating on Jotec’s EndoVascular

Implant Placement Devices

Hydromer, Inc. (HYDI.PK) and Jotec GmbH have entered into a Supply and Support Agreement.

Under the terms of this agreement, Jotec is licensed to use proprietary Hydromer® hydrophilic coatings on various Jotec Endovascular placement devices, such as their CE approved E®-asy plus Introducer Sheath. This Hydromer coating system becomes slippery when made wet and will ease the introduction of Jotec’s endovascular catheter and stent graft systems into the vascular system.

As a separate part of this new agreement, Hydromer has also provided our proprietary internally designed and built catheter coating machines as a validated “turn- key” solution.

“We are delighted with our relationship with Jotec and with having our Hydromer coating technology applied to Jotec’s innovative and successful endovascular devices”, commented Martin von Dyck, Executive Vice President of Hydromer, Inc., adding, “This particular Hydromer coating system is used worldwide on other Pebax® and Nylon neurovascular, cardiovascular and cardiac stent delivery catheters.”
