Connecticut Patent of the Month – April 2024
Lumeda Inc. has been granted a patent for their photodynamic therapy (PDT) probe. This innovative device offers precise interstitial delivery of therapy light, addressing the limitations of existing methods and devices in the field.
At the heart of Lumeda’s invention is a sophisticated PDT delivery device, comprising a housing with a handle for easy maneuvering during procedures. The device features a fiber lock orifice at the back end and a probe insertion orifice at the front end, facilitating seamless operation. A tube retraction groove between these orifices ensures smooth retraction of the insertion probe.
Speaking of the insertion probe, Lumeda’s device incorporates a stepped hollow cylinder with an insertion needle at the distal end, allowing for accurate targeting of tissues. The insertion probe includes a bevel point for enhanced precision.
But Lumeda didn’t stop there. They’ve designed an advanced probe retraction mechanism, featuring a drive wheel, probe release mechanism, and drive ratchet wheel, among other components. This mechanism enables precise control over the insertion and retraction of the probe, ensuring optimal delivery of therapy light.
Lumeda’s PDT delivery device includes a fiber locking mechanism, spring cavity, and tapered cavity, further enhancing its functionality and reliability. The fiber locking mechanism securely holds the optical delivery fiber in place, while the spring cavity and tapered cavity contribute to the device’s smooth operation.
In terms of methodology, Lumeda’s approach is straightforward yet comprehensive. It involves positioning the insertion probe and fiber locking mechanism, inserting the insertion probe and optical delivery fiber, and threading the delivery tip through the insertion needle. This method ensures accurate and efficient delivery of therapy light to the target area.
With Lumeda’s PDT delivery device and method, healthcare professionals can offer patients a more effective and precise photodynamic therapy experience. Lumeda continues to push the boundaries of innovation in medical technology, bringing us one step closer to better patient outcomes and improved quality of life.
