Problems solved by technology

An incorrect pressure differential results either in too much fluid drainage or inadequate drainage.
The system 20 illustrated in FIG. 1 is relatively cumbersome and essentially relegates the patient to the hospital bed.
Moreover, movement of the patient c...

Embodiment Construction

[0037] One embodiment of the intracranial drainage system 50 of present invention is shown in FIG. 2 mounted to the head 52 of a patient. FIG. 3 shows this system 50 in isolation and partially exploded. The drainage system 50 comprises a drainage catheter 54 having a distal end 54a with a plurality of drainage apertures 56 therein. A proximal end 58 of the drainage catheter 54 is in fluid communication with an inlet 60a of a one-way pressure-responsive valve 60. The proximal end 58 may connect directly to the inlet 60a of the pressure-responsive valve 60, or may be connected via an intermediate three-way junction or stock cock 62 having a sampling port 64. A mating pair of connectors 66 may be utilized so that the drainage catheter 54 can be decoupled from the remainder of the system if necessary.

[0038] A drainage tube 70 attaches to an outlet 60b of the pressure-responsive valve 60 and has a coupling 72 on its opposite end that mates with an inlet to 74 of a reservoir bag 76. The s...

Abstract

A portable systems release fluid pressure with a cavity within a patient. These systems include a drainage catheter, a pressure-responsive one-way valve, and a fluid reservoir all adapted to be mounted in proximity to the cavity being drained. One system in particular is used in relieving intracranial pressure. This intracranial pressure relief system may include a headband to which are mounted the one-way valve and reservoir. The drainage catheter may have mounted thereon a cranium seal formed of a soft material that contacts the inner wall of a cranium bore hole. The cranium seal may have threads to facilitate advancement into the bore hole.

Description

INCORPORATION BY REFERENCE[0001] Applicant incorporates herein by reference any and all U.S. patents, U.S. patent applications, and other documents cited or referred to in this application or cited or referred to in the U.S. patents and U.S. patent applications incorporated herein by reference.DEFINITIONS[0002] The words "comprising," "having," and "including," and other forms thereof, are intended to be equivalent in meaning and be open ended in that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items, or meant to be limited to only the listed item or items.BACKGROUND OF INVENTION[0003] Frequently it is necessary to drain fluids, particularly liquids, from various cavities in the body. For example, hydrocephalus arises when the outflow of cerebrospinal fluid (CSF) is obstructed, which collects in the ventricles of the brain and produces an increase in the intracranial pressure. Left untreated, hydrocephalus can result in ...
