A shunt system quick connector assembly to quickly connect and disconnect a catheter to a hydrocephalus shunt system comprising a valve in a valve housing. The catheter is affixed to the quick connector assembly. The quick connector assembly snaps over an external barb on the valve housing of the shunt system with an audible sound, so that the surgeon knows that connection has been made. The connector assembly can be operated quickly, minimizing the time for the surgical procedure and the opportunity for infection. The connector assembly has smooth surfaces to minimize the growing of tissue into the connection.

A quick connector assembly for connection to a hydrocephalus shunt system, the hydrocephalus shunt system including a valve in a valve housing, a barb element having an external barb, and a catheter, the quick connector assembly comprising: a connector body comprising a one-piece body, a fluid passage extending through the one-piece body, the catheter affixable to one end of the one-piece body; a resilient holding element comprising a radially inwardly projecting member disposed to resile after passage of the external barb to retain the external barb of the barb element with at least a portion of the barb element in a connected position within the one-piece body, wherein the holding element comprises an annular rib unitary with the one-piece body and integrally formed in an interior surface of the one-piece body; and a sealing element disposed to provide a fluid seal against the barb element in the connected position, wherein the sealing element comprises a sealing surface formed by a smooth, tapered section of the internal surface of the one-piece body. 13. The assembly of claim 12, wherein the connector body includes a smooth exterior surface. 14. A shunt system comprising: the quick connector assembly of claim 12; a hydrocephalus shunt system comprising: a valve housing having a valve therein, a barb element having an external barb extending from the valve housing, the barb element insertable in the connector body of the quick connector assembly with the barb element retainable by the holding element, and a catheter affixed to the end of the quick connector assembly. 15. A method for connecting a catheter to a hydrocephalus shunt system, comprising: providing the quick connector assembly of claim 12 with the catheter affixed to the end of the connector body; and inserting a barb element into the connector body until an external barb on the barb element is retained beneath the holding element of the quick connector assembly. 16. A quick connector assembly for connection to a hydrocephalus shunt system, the hydrocephalus shunt system including a valve in a valve housing, a barb element having an external barb, and a catheter, the quick connector assembly comprising: a connector body having a fluid passage extending therethrough, the catheter affixable to one end of the connector body; a resilient holding element comprising a radially inwardly projecting member disposed to resile after passage of the external barb to retain the external barb of the barb element with at least a portion of the barb element in a connected position within the connector body, wherein the holding element comprises a plurality of resilient arms attached to the connector body, the radially inwardly projecting member disposed at the end of each resilient arm, and wherein the resilient arms comprise lever arms attached to the connector body with a fulcrum extension at a midregion of the lever arms; and a sealing element disposed to provide a fluid seal against the barb element in the connected position. 17. The assembly of claim 16, wherein the radially inwardly projecting member comprises a tooth element. 18. The assembly of claim 16, wherein the sealing element comprises a sealing surface formed by an internal surface of the connector body. 19.
