Kit comprising adhesive hydrogel and impregnating fluid

A kit of parts ready to use in a surgical method comprising a first part and a second part, wherein

• the first part is a shaped article in the form of a patch for application on a sutured site, a stapled site or a stoma site of a subject in need thereof, the patch comprising a hydrogel support layer, optionally a backing layer, and optionally functional components selected from sensing components, and therapeutic components, and
• the second part is an impregnating fluid for application on a sutured site, a stapled site or a stoma site of a subject in need thereof, and on the patch, wherein the impregnating fluid comprises a pharmaceutically acceptable liquid, curable monomers, optionally curing initiators, and optionally additives;
• wherein the curable monomers present in the impregnating fluid are in an uncured, monomeric state when the impregnating fluid is not applied on the patch, and
• wherein
• the hydrogel support layer comprises a non-degradable, synthetic hydrogel;
• and
• the optional backing layer comprises a non-adhesive polymer;
• and
• the liquid is selected from water and/or glycerol;
• and
• the optional curing initiator is adapted for curing the curable monomers;
• and
• the patch and the impregnating fluid are each separately packed for transport and/or sale and prior to the use in a surgical method;
• and
• the patch is impregnated with the fluid shortly before application on a tissue, such that curing of the monomers that are present in the impregnating fluid is initiated after application of the patch.
