Abstract
Abstract A liquid drainage system comprising, an elongated catheter having a lumen, a distal end for placement in a patient, and a proximal end. The system has a retaining assembly comprising, a base plate for placement adjacent the patient, and an upright wall extending substantially peripherally around the base plate and having an opening, with the base plate having an aperture to receive the catheter and an upright retaining member having a groove extending from the aperture to receive the catheter in the groove. The catheter is wound in at least one coil inside the wall and extends toward the wall opening.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
158 words
A liquid drainage system, comprising: an elongated catheter having a lumen, a distal end for placement in a patient, and a proximal end; and a retaining assembly comprising, a base plate for placement adjacent the patient, an upright outer wall extending substantially peripherally around the base plate to define a space and having an opening in the wall, said base plate having a lower surface, an aperture in the base plate approximately the size of the catheter to receive the catheter and an upright retaining member within the space defined by the wall and attached to the base plate adjacent the aperture, the retaining member having an upper surface defining a groove between opposed sides of the retaining member and extending directly from said aperture to receive the catheter in the groove, said catheter being wound around the retaining member only within the wall in at least one coil inside the wall and extending toward the wall opening.
Claim 2
Dependent Claim
