Abstract: A medical device assembly comprises a medical device, such as a urinary catheter, comprising an insertable part and a non-insertable part. The insertable part comprises an elongate shaft provided with a hydrophilic coating or surface. The assembly further comprises a wetting fluid compartment arranged to encircle at least a part of the medical device, and preferably at least a part of the non-insertable part, and an aqueous fluid arranged in the wetting fluid compartment. At least one of the aqueous fluid and the hydrophilic coating or surface comprises at least one surfactant. The hydrophilic coating or surface is maintained essentially separated from the aqueous fluid, and arranged to become wetted by movement of the elongate shaft through the wetting fluid compartment.

Abstract: The invention relates to promotion of a process for regeneration of an injured nerve using a plurality of guiding means, preferably a plurality of guiding fibres, presenting an in vivo biodegradability being such that at least a majority of said guiding means becomes essentially disintegrated by degradation (and/or dissolution) during a pre-contact period extending from application of the device at the injured nerve up to a first occurrence of a re-established (regenerated) contact between the ends of the injured nerve. During a post-contact period extending from the end of the pre-contact period and up to the end of the regeneration process, the disintegrated guiding means will provide no substantial axon growth guiding function and no substantial axon growth blocking effect.
