Publication number: 20240350128Abstract: Systems, methods and compositions relating to delivering synthetic polymer formulations to the body are described, which can be used by a range of medical personnel including those with minimal experience and training. Under some embodiments, the present invention relates to systems and devices for delivering polymer formulations to a body cavity (e.g. peritoneal cavity) to reduce or stop bleeding. Under some embodiments, an initial percutaneous access pathway is first formed using a delivery device with a probe and needle mechanism that automatically stops the advance of the device upon insertion into a body cavity or space, thus minimizing user error and improving patient safety. The hollow probe then allows transmission of polymer, mixed with gas and/or additional substances, from a holding chamber or canister to flow through the device and hollow probe into the patient's anatomic cavity or space of interest, stopping expansion when the device senses the appropriate pressure.Type: ApplicationFiled: July 1, 2024Publication date: October 24, 2024Inventors: Ross I. Donaldson, Timothy Fisher, Oliver Buchanan, Jon Armstrong, John Cambridge

Publication number: 20240158596Abstract: Disclosed herein is a pressurized therapeutic composition configured to be stored in a valved container designed to maintain an inverse thermosensitive polymer foam composition under pressure and dispense the composition upon opening the valve thereof. After the composition is dispensed from the container the evaporation of an expanding component (e.g., compressed gas or volatile liquid) can cause the inverse thermosensitive polymer solution to foam. The reduced pressure produced from dispensing the inverse thermosensitive polymer solution can reduce its temperature so as to facilitate distribution in a more liquid foam form. The inverse thermosensitive polymer solution can undergo a reverse phase change from a liquid to a gel upon warming (e.g., once dispensed onto or into a body part).Type: ApplicationFiled: October 12, 2023Publication date: May 16, 2024Inventors: Ross I. Donaldson, Jonathan Armstrong, Oliver Buchanan, John Cambridge, Timothy Fisher, Nely Cristerna
