US Patent 11986618 Medical connector having elongated portion within seal collar

Some embodiments disclosed herein relate to medical connectors with a housing comprising a proximal body member and a base member that form an internal cavity with a proximal abutment surface. An elastomeric seal without a guide member is positioned within the internal cavity. A rigid, hollow elongated portion is located within the internal cavity such that in an open configuration, a tip of the elongated portion is more proximal than a proximal surface of the elastomeric seal. A distal portion of the elastomeric seal is seated radially within a region surrounded by a plurality of longitudinally extending protrusions.
