Abstract
This disclosure generally relates to multi-lumen catheters, ports, and adapters for delivering fluid to a tissue or cavity in a subject and methods thereof. The multi-lumen catheters disclosed herein comprise a catheter comprising a guide lumen configured to receive a stylet (e.g., for placement of the catheter within a cavity/tissue) or a stylet port of the adapter (e.g., to anchor the catheter to the adapter); and a fluid lumen configured to receive a fluid port of the adapter (e.g., to receive a fluid via the fluid port into the fluid lumen). In some embodiments, the multi-lumen catheter is size-adjustable. Other aspects of the disclosure relate to systems comprising multi-lumen catheters in fluidic communication with an adapter in fluidic communication with a reservoir. Additional aspects of the disclosure relate to methods of inserting the described catheters, ports, adapters, and/or systems into a tissue or cavity of a subject (e.g., brain tissue).
