HINGHAM, Mass.–(BUSINESS
WIRE)–Phase One Medical, L.L.C. a privately held medical device
research and development company announced today that the U.S. Patent and
Trademark Office has issued a second patent covering their Distal Locking
Hemodialysis Catheter Technology. The patent (USP# 8,052,659) entitled:
“Catheter Device” provides broadened claims for the companys methods of
opening and closing the distal end of a hemodialysis catheter.

The Phase One catheter system is a chronic hemodialysis catheter utilizing an innovative
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.”

Approximately 400,000 patients receive hemodialysis three
times a week in the United
States. Hemodialysis requires access to a
patients vascular system. It is estimated that up to 30% of patients receive
their vascular access through the use of chronic hemodialysis catheters.
Clinical problems associated with the use of chronic catheters include
infection, intraluminal thrombosis, distal tip occlusion and complications
caused by loss of catheter lock solutions.

Said Don Woods, Partner, Phase One Medical, “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.”
