Publication number: 20210016068Abstract: 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 (MRI)). Movement of the flow indicators caused by fluid flowing through the catheter can be detected using MRI, thereby providing a reliable indication as to whether the catheter is partially or completely blocked.Type: ApplicationFiled: May 4, 2020Publication date: January 21, 2021Inventors: PJ Anand, Deep Arjun Singh, Morgan Brophy, Timothy Fallon, Robert Degon, Matthew Attar, Anthony Wong, Allison Waller, Andrew East, Jon T. McIntyre

Patent number: 10806396Abstract: Systems and methods for delivering a drug with a tracer or contrast agent are disclosed herein, as are systems and methods that generally involve CED devices with various features for reducing or preventing backflow. In some embodiments, CED devices include a tissue-receiving space disposed proximal to a distal fluid outlet. Tissue can be compressed into or pinched/pinned by the tissue-receiving space as the device is inserted into a target region of a patient, thereby forming a seal that reduces or prevents proximal backflow of fluid ejected from the outlet beyond the tissue-receiving space. In some embodiments, CED devices include a bullet-shaped nose proximal to a distal fluid outlet. The bullet-shaped nose forms a good seal with surrounding tissue and helps reduce or prevent backflow of infused fluid.Type: GrantFiled: January 26, 2015Date of Patent: October 20, 2020Assignee: Alcyone Lifesciences, Inc.Inventors: Deep Arjun Singh, PJ Anand, Martin Lee Brady

Patent number: 10792480Abstract: Systems and methods for flushing shunt systems are disclosed herein. In some embodiments, a flusher includes a pinch tube that extends over a flush dome such that a user can simultaneously close the pinch tube and actuate the flush dome with a single motion. Flushing and refill valves of the system can be disposed in a cartridge that is laterally-offset from the flush dome, advantageously reducing the height profile of the flusher. Flushers with integrated shunt valves are also disclosed, as are shunt systems with restricted and unrestricted modes for selectively limiting the instances in which a user can open an auxiliary flow path through the system.Type: GrantFiled: October 12, 2017Date of Patent: October 6, 2020Assignee: Anuncia, Inc.Inventors: P J Anand, Deep Arjun Singh, Greg Eberl, Andrew East, Morgan Brophy, Ayesha Arzumand, Stela Moura, Loredana Guseila
