Delivery Device for a Photo-Crosslinkable Hydrogel to Repair Intervertebral Disc Herniation
- 详细技术说明
- A device used in minimally invasive microdiscectomyprocedures to amend intervertebral disc herniations by injecting andcrosslinking a photo-crosslinkable hydrogel.
- *Abstract
-
Our device, for intervertebral disc herniation repair, iscomposed of two elements allowing both delivery and curing of a cross-linkablehydrogel solution. The hydrogel would be delivered to the surgical site using apreloaded syringe mounted on a screw driven needle retraction mechanism, thusallowing for a range of motion of the needle. Upon hydrogel delivery, anintegrated light source is activated and with the frequency necessary tocrosslink the hydrogel.
This device allows for the controlled delivery and activationof a hydrogel solution to initiate tissue regeneration within theintervertebral disc injury site. Current treatments stand only to removeherniated tissue, this delivery device is envisioned to play an essential role insignificantly improving the standard of care for discectomy procedures.
The occurrence of subsequent herniations are detrimental to patienthealth because they elicit the same symptoms of initial herniation, warrantingadditional surgery. The standard of care in hernia treatment is discectomy andcan be executed as minimally invasive discectomy. This invention will act toaccurately deliver the hydrogel to the site of the incision in a controlledmanner.
Potential Applications
- Minimally invasive discectomy
Advantages
- Combination device for both delivering and crosslinking of hydrogel
- Compatible with current minimally invasive procedures
- Potential to minimize occurrence of subsequent herniation oftreated disc
