HINGHAM, Mass.— The U.S. Patent and Trademark Office has issued a second patent covering Phase One Medical's Distal Locking Hemodialysis Catheter Technology.
The patent (USP# 8,052,659) entitled: "Catheter Device" provides broadened claims for the company's methods of opening and closing the distal end of a hemodialysis catheter.
The Phase One catheter system is a chronic hemodialysis catheter using a distal locking system that is opened to allow patients to receive hemodialysis and is then closed at the completion of dialysis treatment. "We are very pleased to have received this additional patent," said Adrian Ravenscroft, partner, Phase One Medical. "We believe our strengthened patent portfolio and the unique design elements of our catheter will become a game changer."
Don Woods, partner, Phase One Medical, added that "having the ability to open and close the distal end of a chronic hemodialysis catheter is significant. For the first time, clinicians will be able to manage the catheter lumens with confidence when the distal lock is closed. Lock solutions will not leak into the systemic circulation and lumens will remain blood free. As a result, we believe this technology will have an impact on the historical complications and cost associated with use of chronic hemodialysis catheters."
