Abstract
Medical devices, and more particularly, devices, methods and compositions for sealing tissue puncture openings of patients after surgical operations are provided. A puncture wound sealing apparatus includes a positioning device having a depth sensing mechanism capable of providing feedback to an operator for the precise placement of an implant that is preferably resorbable and swellable after implantation. Such an implant provides for efficient sealing of the tissue puncture opening thus avoiding complications after surgical procedures in which blood vessels are punctured.
