Abstract:
A system for coupling a proximal end of a medical electrical lead to a medical device, comprising:a connector pin terminating the proximal end of the lead and having a predetermined diameter; and an up-sizing sleeve having an internal surface and an external surface, a distal opening, and a proximal opening, one or more interior sealing rings, and one or more relatively rigid support members extending along the internal surface; wherein the internal surface forms a lumen to engage the proximal end of the lead; the external surface conforms to predetermined dimensions when the proximal end of the lead is engaged within the lumen of the up-sizing sleeve; the distal opening receives the proximal end of the lead into the lumen; the connector pin extends proximally beyond the proximal opening, for a predetermined length, when the proximal end of the lead is engaged within the lumen of the up-sizing sleeve; the one or more interior sealing rings provide a fluid tight seal with the proximal end of the lead engaged within the lumen of the up-sizing sleeve; and the one or more support members prevent deformation in order to maintain the predetermined dimensions of the external surface of the up-sizing sleeve when the proximal end of the lead is engaged within the lumen of the up-sizing sleeve.
