Abstract
A surgical cutter device for producing a skin incision of controlled length and depth at a guidewire skin puncture location is described. The cutter is particularly useful for making incisions for the insertion of catheters. In addition, there is described a device which takes full advantage of such precisely formed skin incisions, comprising a subcutaneous cuff for sealing the entrance incision for a catheter and providing antimicrobial action at the sealed entrance, and an introducer for inserting the cuff subcutaneously along the associated catheter. A preferred method for using the cutter, cuff and introducer is also described.
