Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: For treatment of a patient who has a lesion in each of left lower limb artery and right lower limb artery, lesions at both sides can be rather easily and completely treated. A catheter is introduced from an artery of an arm of the patient, and an atherectomy catheter is used for a lesion at one side and continuously used for a lesion at the other side without being extracted to the outside of a human body, and thus damage of an excision portion of the atherectomy catheter and an unexpected situation such as no passage through twisted blood vessels are avoided so that a burden on the patient can be reduced, the treatment can be completed within a short time, and cost reduction can be achieved by reducing the number of catheter to be used.

Abstract: A catheter including a sheath configured to be inserted into a lumen; a drive shaft inserted into the sheath; an image information acquiring unit fixed to a distal end of the drive shaft and acquires image information; a hub which moves the drive shaft in an axial direction of the sheath; an outer tube on a proximal end side of the sheath and includes a first connector at a proximal end thereof; a second connector which includes on a proximal end side of the outer tube a male connector able to be connected to and disconnected from the first connector; and an inner tube on a distal end side of the hub, that moves with respect to the outer tube along with the movement of the hub.

Abstract: A diagnostic method, a treatment method and a medical system are capable of selecting reasonably and effectively a favorable order of treatments capable of achieving desired effects when lesion areas in both left and right lower limb arteries are treated in order from an artery of an arm. The method of treating a patient having lesion areas X in both left and right lower limb arteries involves determining the lesion area X to be treated first, based on at least the two pieces of selected comparative information on each of the lesion areas X.

Abstract: In a method for diagnosing, validation of diagnosis and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a smaller vessel diameter 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 vessel diameter lesion is to be treated next, then treating the lesions substantially continuously.

Abstract: A method is disclosed for diagnosing, validating and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a shorter 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 longer lesion is to be treated next, then treating the lesions substantially continuously.

Abstract: A biodegradable stent that is degraded in a living body includes a stent body that is made of a biodegradable material and is deformed to have an expanded diameter in the living body; and a biodegradable drug-coating portion formed on the stent body. The drug-coating portion is degraded, in an expansion retention period during which an expansion retention force (radial force) of the deformed diameter-expanded stent body that acts on an inner wall of a lumen thereof is maintained, and before 60% of a degradation period from indwelling of the stent body in the living body to complete degradation thereof elapses.

Abstract: A stent Includes a stent body formed by a strut. The stent body is cylindrically-shaped and extends in an axial direction. The stent body includes a plurality of helical portions and an annular portion. The strut is helically-shaped along the axial direction to form the plurality of helical portions and the strut is annularly-shaped in the circumferential direction to form the annular portion. Each of the plurality of helical portions has a distal end point and a proximal end point. The plurality of helical portions include a first helical portion and a second helical portion adjacent to the first helical portion in the axial direction. The annular portion is disposed between the first and second helical portions in the axial direction. At least one of the distal and proximal end points of the plurality of helical portions is directly connected to the annular portion.

Abstract: A stereoscopic-image game playing apparatus displays a screen image for right eye and a screen image for left eye on LCD 105, outputs images of the player obtained by cameras 103a and 103b to the receiving side, and displays images corresponding to the right half face and the left half face of the player based on the player's images on LCD 107. The images displayed on the LCD 107 are used as figures for selectively introducing lights from the screen images on the LCD 105, by lens 106, to the right and left eyes of the player. This enables stereoscopic vision without glasses for separating images respectively for the player's right and left eyes, and allows the player to move from the initial position.
