Abstract:

Header assemblies for coupling one or more cardiac leads to a cardiac stimulator are described. The header assemblies can include a header housing with a lead receiving header bore. The header assemblies can further include a connector assembly injection molded within the header housing and including a connector housing, at least one biasing member and at least one biasing member cover. The connector housing can include a first connector bore aligned with the header bore and at least a second connector bore. The biasing member can be in the form of a coiled spring or bent wire and disposed within the second connector bore such that a portion of the biasing member projects into the first connector bore. In this way, a lead proximal end can be urged against a first connector bore wall. The biasing member cover can secure the biasing member and seal the second connector bore.
