A sterile assembly and method for protecting and affixing an indwelling device such as an elongated catheter, or pacer lead, in an incision in the human body includes an elongated, hollow tubular, sheath of transparent, relatively limp, impervious plastic having at its proximal end a dome of self-supporting plastic adherable around the incision and having, at its distal end, an elongated tube, several inches in length, of self-supporting plastic. The sheath is shipped accordion folded onto the tube to save space. The indwelling device is sleeved into the sheath with the conventional nub at its distal end wedged in the bore. The proximal end is introduced into the incision and the domed distal end of the sheath is adhered around the incision so that the device is contamination free. The device and sheath are then gripped in the slot of a clamp and the clamp adhered to the body near the incision or elsewhere. The Introducer may be withdrawn into the sheath away from the incision, while remaining sealed in the sheath.

A sterile assembly for protecting an elongated indwelling device having a proximal end, for insertion in an incision in the human body, and a distal end, for connection to a medical device outside the human body, said assembly comprising: an elongated, tubular sheath of sterile, impervious, limp, flexible, plastic substantially co-extensive in length with said indwelling device and having a proximal end and a distal end; an elongated, bell shaped dome of self-supporting plastic sealingly affixed to the proximal end of said sheath: said dome being shaped and dimensioned to cover said incision and keep the incision and indwelling device free of contamination with air and having an annular base flange with a skin contacting surface covered by a layer of adhesive adapted to be affixed around said incision, said surface normally covered by a removable strippable sheet and a hollow support tube of said self-supporting plastic, and of predetermined length, sealingly connected to the distal end of said sheath, said tube having an axial bore which tapers from its outer end in a progressively reduced diameter to its inner end for slidably fitting and sealing the conventional nub on said indwelling device.
