Embodiment Construction

[0100] Provided herein are systems and methods generally related to diverting fluid, such as diverting cerebrospinal fluid in the treatment of hydrocephalus. The present invention provides self-cleaning catheters comprising separate tips configured such that a pulsating flow of fluid in a lumen into which the catheter is inserted enables the tips to strike each other, thereby clearing obstructions. Catheters with built-in flow indicators are also available. An exemplary flow indicator includes a protrusion that extends radially inward from an inner surface of the catheter and that includes an imageable portion (eg, a portion visible under magnetic resonance imaging (MRI)). Movement of the flow indicator caused by fluid flowing through the catheter can be detected using MRI, providing a reliable indication as to whether the catheter is partially or fully occluded. Systems and methods for flushing a shunt system are also disclosed herein, as are various systems and methods for ...

Abstract

Systems and methods are provided herein that generally involve shunting fluid, e.g., shunting cerebrospinal fluid in the treatment of hydrocephalus. Self-cleaning catheters are provided which include split tips configured such that pulsatile flow of fluid in a cavity in which the catheter is inserted can cause the tips to strike one another and thereby clear obstructions. Catheters with built-in flow indicators are also provided. Exemplary flow indicators include projections that extend radially inward from the interior surface of the catheter and which include imageable portions (e.g., portions which are visible under magnetic resonance imaging (MRl)). Movement of the flow indicators caused by fluid flowing through the catheter can be detected using MRl, thereby providing a reliable indication as to whether the catheter is partially or completely blocked. Systems and methods for flushing a shunt system and for opening auxiliary fluid pathways through a shunt system are also disclosed herein.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 755,018, filed January 22, 2013, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to systems and methods for diverting fluid, such as cerebrospinal fluid in the treatment of hydrocephalus. Background technique [0004] Shunt systems for transferring bodily fluids from one area of ​​the body to another are well known. For example, shunt systems are commonly used in hydrocephalus treatment to drain excess cerebrospinal fluid (CSF) from the ventricles of the brain. A typical shunt system includes a one-way pressure control valve implanted under the skin. A ventricular catheter extends from one side of the valve into the ventricle. A drain catheter extends from the other side of the valve to a drain site, such as the abdominal cavity. [0005] After implantation and use for a s...
