Abstract
The telescoping catheter shunt system comprises first and second telescoping tubings, the first tubing being connected to an anchoring connector mounted in a burr hole, the connector being connected to a catheter adapted to be inserted into a body cavity to be drained and being received within the second tubing which has a larger diameter than the first tubing. A valve assembly is connected to the second tubing and has a control mechanism for controlling the drainage of fluid from the cavity in response to pressure of the draining fluid. The first tubing has a flange at the proximal end thereof which has an outer diameter slightly greater than the inner diameter of the second tubing in which it is received to establish a friction fit between the outer surface of the flange and the inner surface of the second tubing that defines a primary seal for keeping body fluids other than the draining fluid out of the system. The second tubing has an annular stop member at the distal end thereof through which the first tubing extends such that upon telescoping of the tubings, relative movement between them is limited by engagement of the flange with the stop member so that the tubings cannot separate. The valve assembly is connected to a drainage catheter adapted to be positioned in a body cavity into which the draining fluid is deposited. The method for draining fluid from a body cavity, e.g. ventricle of a child, utilizing the telescoping catheter shunt system defined above.
