Abstract:

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. Once reaching the body cavity, the polymer formulation functions to reduce and/or stop bleeding.

Assignee:

PACIFIC GAS AND ELECTRIC COMPANY - San Francisco CA

International Classification:

F16K 51/00

US Classification:

137 1, 137581

Abstract:

Some embodiments include a method of providing substantially uninterrupted gas service by coupling at least one gas cylinder to a portable tanking assembly. The tanking assembly can include a cart including a rear frame and a coupled carrier frame supported on an axle with wheels. In some embodiments, the carrier frame can include a caged regulation assembly housing at least a portion of a regulation apparatus with an upstream supply end coupled to a downstream delivery end. In some embodiments, the regulation apparatus includes a primary regulator coupled a one relief valve. The relief valve can be coupled to a downstream regulator, coupled to a water column gauge. In some embodiments, the regulation apparatus further includes a delivery valve. In some embodiments, the delivery valve comprises a distribution manifold assembly including a manifold and a plurality of distribution couplers coupled to the manifold.
