When a nerve in the peripheral nervous system is torn or severed, it can take a long time to regenerate – if it does so at all. Depending on the location of the injury, it can leave the affected part of the patient’s body numb and/or paralyzed for years, or even for the rest of their life. Now, however, scientists from Israel’s Tel Aviv University have created a gel and an implant that they claim could vastly aid in the healing of damaged nerves.
The implant is a tiny pliable biodegradable tube, that is placed around the two cut ends of the nerve. It serves to line them up with one another and hold them together end-to-end, plus its inner surface is coated with the gel.
