Abstract

This application discusses, among other things, a header assembly for coupling a medical electrical lead to a medical stimulating device including a header having a capture mechanism within a bore of a lead retention device. In an example, when the lead retention device is retracted from the bore, the capture mechanism prevents the device from falling out. In another example, the header assembly has a vent disposed within the bore of the lead retention device that permits unrestricted flow of air when the lead retention device is retracted from an engagement surface.
