A method tor the preparation of a highly polarized nuclear spins containing sample of an organic or inorganic material, containing H or OH groups or adsorbed water molecules. Such highly polarized nuclear spins containing samples can be subjected to nuclear magnetic resonance (NMR) measurement and/or can be thawed and immediately administered to an individual undergoing a magnetic resonance imaging (MRI) scan. The method is based on generating unstable radicals on the surface of the sample in the presence of ionized environment followed by cooling the sample to cryogenic temperatures. A device for carrying out a particular step of said method is also discloses.

In a method of treating erectile dysfunction in a patient, a predetermined course of external counter-pulsation treatment is applied to a lower body portion of the patient. After the predetermined course of external counter-pulsation treatment is applied, a predetermined course of low intensity shockwave treatment is applied to a penile area of the patient. After the course of low intensity shockwave treatment, a predetermined course of carboxy therapy is applied to a corpora cavernosa of the patient.

A method for generating microbubbles may include providing a syringe having a barrel defining an interior volume, a plunger, a tip and a check valve assembly. The check valve assembly may have an inlet port; a check valve that is configured to open when the plunger is drawn back by a user; and a nozzle in fluid communication with the interior volume and, when the check valve is open, in fluid communication with the inlet port. The method may include drawing liquid into the interior volume; removing a seal from the inlet port and drawing gas adjacent the inlet ports into the interior volume to form microbubbles in the liquid already drawn in; coupling the tip to an intravenous line associated with a patient undergoing a bubble study; and depressing the plunger to force the liquid and the formed microbubbles into the intravenous line.

This application relates to the field of injection technology, especially a type of portable carbon dioxide gas injector. The technical solution of the invention includes a storage tube, one end of which is connected with a passage tube, and a passage valve is provided at the end of the passage tube away from the storage tube. A piston adapted to the injection device body is arranged inside the storage tube. A driving assembly for driving the piston is arranged on one side of the piston away from the passage tube, and a regulating assembly for adjusting the gas storage volume is arranged on the other side of the driving assembly away from the passage tube. The invention achieves quantitative control of the injection amount of carbon dioxide, which can alleviate the discomfort of patients.

Methods and systems for delivering gas-enriched blood within a vasculature of a patient may include providing a gas-enrichment system, the gas-enrichment system comprising a mixing chamber and a blood pump. The process may include inserting a catheter for drawing blood from the patient into a radial artery of the patient. The process may include drawing blood from the radial artery or from a vessel upstream of the radial artery at a blood flow rate without collapsing the artery or vessel to a degree that would substantially impede drawing blood. The process may include generating a gas-enriched blood by mixing the withdrawn blood with a gas-enriched liquid in a mixing chamber. The process may include delivering the gas-enriched blood to the vasculature of the patient.

Catheters for infusion of cardiovascular fluids into blood are disclosed. The cardiovascular fluid may, for example, comprise water highly supersaturated with a gas such as oxygen. Each catheter comprises one or more capillary tubings (or capillaries) through which a cardiovascular fluid flows. The distal end of each capillary is mounted (e.g., potted) preferably flush with an external surface of a catheter sidewall, while the proximal end of each capillary is in fluid communication with a cardiovascular fluid flowing through the lumen of the catheter. The combination of the catheter shape and the orientation of the distal end of each capillary relative to the longitudinal axis of the catheter provides control over the mixing pattern of the cardiovascular fluid with blood flowing within a vascular space such as an aorta.

An automatic robotic apparatus for conducting a minimally invasive surgical procedure includes a robotic arm having a movable member made as the multilink active actuator. The end portion of the multilink active actuator is provided with the connector to which the hollow head for a needle biopsy is attached. The operation of the U-shaped head is under full control of the robotic apparatus computer system. Results of pre-procedure studies of a site of interest and the progression of the surgical procedure are displayed on a monitor of the computer system.

Self-regulating electrolytic gas generator and implant system including the same. In one embodiment, the electrolytic gas generator is a water electrolyzer and includes a polymer electrolyte membrane with an anode on one side and a cathode on the other side. Anode and cathode seals surround the peripheries of the anode and cathode and include inlets for water and outlets for oxygen and hydrogen, respectively. A cathode current collector is placed in contact with the cathode, and an anode current collector, which may be an elastic, electrically-conductive diaphragm, is positioned proximate to the anode. The anode current collector is reversibly deformable between a first state in which it is in direct physical and electrical contact with the anode and a second state in which it distends, due to gas pressure generated at the anode, so that it is not in physical or electrical contact with the anode, causing electrolysis to cease.

A liquid delivery device contains a liquid saturated with a gas in a pressure chamber pressurized to a selected amount. The liquid delivery device may be removed from the pressure chamber to deliver the saturated liquid to a volume.
