With a total of 5 patents to his name, Helliwell's work reflects a commitment to improving patient care through innovative solutions.

Latest Patents

One of Helliwell's latest patents is an epidural device designed for the detection of and needle placement in the epidural space. This device is configured to inhibit or substantially prevent further progression of an epidural needle upon entry into the epidural space. When the needle is inserted into the ligamentum of the patient's back, the device can be pressurized with fluid, using the resistance of the dense ligament to maintain pressure. This pressurization locks a pushing mechanism in place relative to the needle, allowing it to be advanced effectively. Once the epidural space is reached, the fluid enters the space, and the release of pressure disengages the trigger mechanism from the sliding pusher, enabling it to slide along the body of the construct. This innovative device provides the ability to detect the epidural space using pressure loss while preventing the needle from advancing into the dura once the space is reached. Additionally, Helliwell has developed sustained release formulations of polymer-coated local anesthetic agents, which are designed to relieve or manage pain, including postsurgical pain.
