Abstract: The present invention relates to a system for increasing the temperature of a fluid being infused into a patient's body while the infusion is taking place. The present invention also provides for improved monitoring of air in the infusion system such to prevent the introduction of air into the patient's body receiving the fluid infusion. The present invention also provides for a system pump which provides a variable flow rate that serves a vast amount of infusion needs and purposes. A disposable cartridge in accordance with the present invention will allow for the efficient transfer of heat energy to the fluid being infused into the patient's body. The cartridge will further ensure that deleterious amounts of air will not be introduced into the patient's body.

Abstract: An extension rod device is provided for extending an existing spinal fixation system. The device can engage with implanted spinal fixation elements and house extension spinal rods that expand the fixation system to adjacent vertebrae. According to various embodiments, an extension rod device may include one or more extension spinal rods attachable to a transverse connector that is secured between an existing, implanted spinal fixation system. The extension rod device may attach to an existing transverse connector, already implanted with the existing spinal fixation system, or the extension rod device may include a new transverse connector, also for securing to the existing spinal fixation system.
