In a method for sealing an access channel provided for permitting a tool to access a setscrew for securing an electronic lead connector pin to a connector block in the header of a pacemaker or the like, a sealing device having a flexible body with at least one open through hole is formed in a one-step operation. The sealing device has a cross dimension that at least in one direction is larger than a corresponding cross dimension of the access channel. The sealing device is mounted in the header by compressing and positioning the sealing device in the access channel. The difference in cross dimension between the access channel and the sealing device is such that a maintained deformation of the sealing device occurs, which produces a sealing closure of the through hole(s) when the sealing device is mounted in the access channel. |
