Subcutaneous Port With Locking Member

A subcutaneous port assembly comprising:

• a base;
• a connector extending from a first end adjacent to the base to a second end, the connector including a neck portion having a first width at the first end and a shoulder portion having a second width closer to the second end, and a socket defined by an inner surface extending through the connector from the second end;
• a stem extending from the base into the socket, the stem including an outer surface spaced inwardly from the inner surface of the socket;
• a collar including an inner biasing surface having a third width that is greater than the first width of the neck portion and less than the second width of the shoulder portion, the collar operable between a first position where the inner biasing surface is adjacent to the neck portion and a second position where the inner biasing surface is adjacent to the shoulder portion;
• and
• a sealing element disposed within the socket between the stem and the inner surface of the socket, the sealing element surrounding the stem when the collar is in the first position and compressed against the stem when the collar is in the second position.

A locking mechanism for a subcutaneous port assembly, the locking mechanism comprising:

• a connector having a socket and a plurality of threads at a first end of the socket;
• a stem disposed within the socket;
• a sealing element disposed between the stem and the connector within the socket;
• a braided catheter having an end coupled to the stem and surrounded by the sealing element;
• and
• a locking member slidably coupled to the connector and moveable between a first position and a second position along the connector to selectively change the sealing element between a compressed state and an uncompressed state around the catheter.
