Abstract: A method of retrieving calculus in a renal pelvis of a living body involves positioning an enclosure in the renal pelvis, creating convection in the renal pelvis by introducing liquid into the renal pelvis from outside the living body to lift the calculus from a surface of the renal pelvis, retrieving the calculus in the renal pelvis by creating a vacuum in the enclosure while the enclosure is located in the renal pelvis so that the calculus are drawn into the enclosure, wherein the vacuum also draws the liquid into the enclosure, and withdrawing the enclosure from the renal pelvis while the calculus is in the enclosure.

Abstract: A calculus removing device includes an elongated member and a retrieval part fixed to the elongated member. A discharge force is produced in a lumen in the elongated member to discharge fluid in the lumen into the renal pelvis, and a suction force is produced in the lumen to draw fluid into the lumen from the renal pelvis. An outlet communicates with the lumen, and fluid in the lumen is discharged into the renal pelvis through the outlet in the presence of the discharge force. An inlet communicates with the lumen, and fluid in the renal pelvis is drawn into the lumen through the inlet in the presence of the suction force. The retrieval part includes an interior that communicates with the lumen and the renal pelvis, and the interior is configured to receive the calculus in the renal pelvis in the presence of the suction force.

Abstract: A method of removing/retrieving calculus in a renal pelvis includes moving a renal cover part along a ureter toward the renal pelvis, introducing the renal cover part into the renal pelvis, positioning the renal cover part in the renal pelvis so that the renal cover part covers one part of the renal pelvis, while an other part of the renal pelvis is not covered by the renal cover part, introducing fluid into the other part of the renal pelvis, while the one part of the renal pelvis is covered by the renal cover part, to cause the calculus in the other part of the renal pelvis to be washed-out of the renal pelvis, and moving the renal cover part out of the renal pelvis and into the ureter.

Abstract: A device (100) for measuring the amount of water in a subject's body includes a main body part (110) formed in a linear shape and an insertion part (120) extending in a curved shape from one end of the main body part (100). The insertion part (120) includes a tip side insertion part (120-2) having a tip surface (122) to which a sensor unit (121) is fixed and a base end side insertion part (120-1), wherein the sensor unit (121) is brought into contact with a body surface of a subject through a slide mechanism. A protective member (651) liquid-tightly covers the slide mechanism between the tip side insertion part (120-2) and a base end side insertion part (120-1). The protective member (651) smoothly connects the outer peripheral surface of the tip side insertion part (120-2) and the outer peripheral surface of the base end side insertion part (120-1).

Abstract: A recording and reproducing apparatus is disclosed which comprises: an input element supplied with video signals; a recording element for recording the video signals input through the input element onto a storage medium; a reproducing element for reproducing the video signals from the storage medium; a processing element for generating display-ready video signals on the basis of video monitor image signals supplied by the input element and/or on the basis of the reproduced video signals furnished by the reproducing element; and a controlling element for selectively activating, by a single operation of a user, any one of a recording monitor image, a dual-screen display image made of a recording monitor image and a playback image, and a playback image alone.
