Abstract (en)
[origin: WO2021146330A1] Methods, devices and materials are for in situ formation of an implant for treating a nerve. A treatment site is positioned within a cavity defined by a form. A transformable media is introduced into the cavity to surround the treatment site. The media undergoes a transformation from a relatively flowable state to a relatively non-flowable state to form a protective barrier surrounding the treatment site. The hydrophilic media cooperates with the hydrophobic surface of the cavity to facilitate rapid release of the implant from the cavity following the transformation. The implant may be a growth inhibiting nerve cap to inhibit neuroma formation following planned or traumatic nerve injury, a growth permissive conduit for facilitating reconnection of a severed nerve, or an anchor for stabilizing a pain management electrode with respect to a nerve. Access to the nerve treatment site may be open surgical or percutaneous.
