Abstract
The present invention is directed to a sealant patch for use on or over sensitive tissue, comprising: a flat, flexible, bioresorbable substrate coated by a moisture-activated adhesive on one side thereof, wherein said adhesive is at least partially inactivated in a first portion of said patch, but remains active in peripheral areas surrounding the first portion. The adherence of the first portion to the tissue is weaker versus adherence in the peripheral areas. The adhesive in the first portion is fully or partially inactivated or pre-reacted prior to application of the sealant patch to the tissue.
