A diagnostic method, a diagnostic system, and a control method of a diagnostic system that can detect specific behavior of an elongated body easily and with high accuracy are provided. The diagnostic method is a diagnostic method for diagnosing the behavior of a guiding catheter having a distal end and a proximal end in a biological lumen. The diagnostic method includes inserting the guiding catheter into the biological lumen from the distal end and detecting energy that has passed through a body after irradiating the inside of the body with the energy. The diagnostic method also includes identifying the position of the guiding catheter in the body by the detected energy and comparing the identified position of the guiding catheter with an expected position and detecting specific behavior of the guiding catheter from an amount of deviation of the position of the guiding catheter with respect to the expected position.

A medical system recommends a posture of a subject during a medical procedure. The medical system includes a processor and an output device. The processor determines suitable postures of the subject during the medical procedure based on at least one of subject information, including information on a posture of the subject obtained upon a predetermined movement by the subject and information on the procedure. The output device presents one or more of the suitable postures determined by the processor as recommended postures.

A method is disclosed for diagnosing and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a lower stenosis rate lesion to be treated first, catheters and an operation time can be reduced is to be treated first on a priority basis based on diagnostic data, deciding that a higher stenosis rate lesion is to be treated next, then treating the lesions substantially continuously.

Diagnostic method, method for validation of diagnostic method, and treatment method

In a method for diagnosing, validating and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a smaller curvature of lesion to be treated first, catheters and an operation time can be reduced is to be treated first on a priority basis based on diagnostic data, deciding that a larger lesion curvature is to be treated next, then treating the lesions substantially continuously.

A method is disclosed for diagnosing and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a lesion distal to an aortailiac bifurcation is to be treated first, catheters and an operation time can be reduced is to be treated first on a priority basis based on diagnostic data, deciding that a lesion proximal to the bifurcation is to be treated next, then treating the lesions substantially continuously.

A medical assistance device capable of improving handling or an operation of a medical device. The medical assistance device is connected to the medical device which is inserted into a biological lumen and is used in a procedure in the biological lumen.

A flushable catheter device has an outer tube with a first distal end opening to be introduced into a blood vessel and defining a first lumen. An inner tube is disposed in the first lumen with a second distal end opening proximally spaced from the first distal end opening and defining a second lumen. A space axially disposed between the end openings defines an outflow/inflow inhibiting portion which inhibits a flow of fluid out from the first lumen into the into the vessel as a result of a perfusion of a flushing fluid being supplied through the first lumen and into the second lumen.

In a method for diagnosing, validating and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a harder lesion to be treated first, catheters and an operation time can be reduced is to be treated first on a priority basis based on diagnostic data, deciding that a softer lesion is to be treated next, then treating the lesions substantially continuously.

A highly reliable transistor which includes an oxide semiconductor and has high field-effect mobility and in which a variation in threshold voltage is small is provided. By using the transistor, a high-performance semiconductor device, which has been difficult to realize, is provided. The transistor includes an oxide semiconductor film which contains two or more kinds, preferably three or more kinds of elements selected from indium, tin, zinc, and aluminum. The oxide semiconductor film is formed in a state where a substrate is heated. Further, oxygen is supplied to the oxide semiconductor film with an adjacent insulating film and/or by ion implantation in a manufacturing process of the transistor, so that oxygen deficiency which generates a carrier is reduced as much as possible. In addition, the oxide semiconductor film is highly purified in the manufacturing process of the transistor, so that the concentration of hydrogen is made extremely low.

A nonvolatile memory is provided. A semiconductor device (a nonvolatile memory) has a circuit configuration similar to that of a general SRAM. By providing a transistor whose off-state current is small between a stored data holding portion and a power supply line of the SRAM, leakage of electric charge from the stored data holding portion is prevented. As the transistor whose off-state current is small provided for preventing leakage of electric charge from the stored data holding portion, a transistor including an oxide semiconductor film is preferably used. Such a configuration can also be applied to a shift register, whereby a shift register with low power consumption can be obtained.

A medical device includes a catheter having an opening formed in a side portion of the catheter, an infusion tubing extending within the catheter along an axial direction of the catheter; an infusion needle disposed at a distal portion of the infusion tubing, a connecting part which bendably connects the infusion needle to the distal portion of the infusion tubing, and a bending unit by which the infusion needle located inside the catheter so as to face the opening is bent at the connecting part at essentially a right angle with respect to the distal portion of the infusion tubing.

Medical device

A medical treatment device enables an injection needle to accurately puncture brain tissue at a prescribed position and a drug solution to be injected into brain tissue, while avoiding damage to the brain tissue as the injection needle is handled. The use of the medical treatment device involves inflating a first balloon located on the outside of a catheter, directing a distal portion of a puncture needle, which is located inside the catheter, to outside the catheter through an opening in the catheter, after which the first balloon is deflated and a second balloon is inflated, and moving the catheter towards the brain tissue located on the opening side so that the injection needle projecting from the opening punctures the brain region.
