20150133789 | PUNCTURE APPARATUS - A puncture apparatus is disclosed, which can include an elongated insertion portion configured to be inserted into a living body lumen, a puncture needle configured to puncture a living body tissue near the insertion portion from a part different from the living body lumen, with the insertion portion inserted in the living body lumen, a puncture needle guide portion, which movably supports the puncture needle and which determines a puncture path for a needle tip of the puncture needle when the puncture needle punctures the living body tissue, an ultrasonic transmission-reception section in the insertion portion or the puncture needle guide portion, for transmission and reception of an ultrasonic wave, and an image data production section for producing image data for displaying on a display section an image including the living body lumen and a predicted path of the puncture path, based on information acquired by the ultrasonic transmission-reception section. | 05-14-2015 |
20150112308 | METHOD INVOLVING USE OF AN ASSEMBLED INDWELLING ASSEMBLY - A method involves positioning an assembled indwelling assembly adjacent a patient, wherein the assembly includes an inner needle, a hub fixed to the inner needle, a hollow outer member in which the inner needle is positioned, a hub fixed to the hollow outer member, and an elongated member axially overlapping an intermediate portion of the hollow outer member. The method also includes moving a distal portion of the assembly to puncture a blood vessel of the patient with the sharp needlepoint while the elongated member contacts the hollow outer member, advancing the hollow outer member in a distal direction along the inner needle to insert a distal portion of the hollow outer member to a target position in the blood vessel, and moving the inner needle hub in a proximal direction such that the inner needle is pulled out from and entirely removed from the hollow outer member. | 04-23-2015 |
20150112267 | INDWELLING ASSEMBLY - An indwelling assembly includes an inner needle having a sharp needlepoint, an inner needle hub fixed to the inner needle, a hollow elongated outer member in which the inner needle is positioned and movable in a distal direction relative to the inner needle after puncturing the blood vessel to position the elongated outer member at a desired position in the blood vessel, an outer member hub fixed to hollow elongated outer member, a projection removably connected to the outer member hub and configured to be engaged by a finger of the user to apply a force to the projection causing the outer member hub and the hollow elongated outer member to move together with the projection in the distal direction relative to the inner needle and the inner needle hub, and an elongated movable member that is movable relative to the hollow elongated outer member and the outer member hub. | 04-23-2015 |
20150112266 | INDWELLING ASSEMBLY - An indwelling assembly includes an inner needle having a sharp needlepoint at a distal end to puncture a blood vessel of a patient, an inner needle hub fixed to the proximal portion of the inner needle, a hollow elongated outer member in which the inner needle is positioned, with the hollow elongated member being movable in a distal direction relative to the inner needle after puncturing the patient's blood vessel, an outer member hub fixed to the proximal portion of the hollow elongated outer member, an elongated contact member configured to contact an intermediate portion of the hollow elongated outer member, and an elongated movable member movable relative to the hollow elongated outer member and the outer member hub. The elongated movable member is connected to the inner needle hub so that the inner needle hub, the inner needle and the elongated movable member move together. | 04-23-2015 |
20150112134 | TREATMENT INSTRUMENT FOR MEDICAL USE - A treatment instrument for medical use includes a tubular insertion portion that includes a curvable flexible part, the tubular insertion portion being insertable into a body of a patient; and a dilating body that is provided at an outer circumference of the flexible part, the dilating body being configured to dilate in a radial direction relative to the flexible part. The tubular insertion portion includes a reduced-diameter part that is provided at a distal end of the tubular insertion portion in an axial direction, the reduced-diameter part having an outer diameter that is smaller than an outer diameter of the tubular insertion portion at a location proximal of the reduced-diameter part. A distal part of the dilating body is fixed to at least the reduced-diameter part. | 04-23-2015 |
20150111183 | INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD - An information processing apparatus is disclosed having a storage unit storing a plurality of training text items each including a word, a word string, or a sentence. The information processing apparatus presents a training text item among the plurality of training text items stored in the storage unit as voice output or character string display and calculates the speaking speed based on a voice signal that is input after presenting the training text item. The information processing apparatus compares the calculated speaking speed with a preset target speaking speed and reports the comparison result. | 04-23-2015 |
20150094821 | CATHETER FOR FORMING BIOLOGICAL TISSUE HOLDING MEMBER | 04-02-2015 |
20150094731 | BONE TREATMENT SYSTEM - To favorably discharge gas internally present in a device during filling of a bone filling material, a bone treatment system has a shaft that has a flow path which enables a bone filling material to be placed on a space of a radius to flow therethrough, and a filling balloon that communicates with the flow path in a distal portion of the shaft and that is filled with the bone filling material. Furthermore, the bone treatment system includes a gas discharge portion that causes air (gas) inside the flow path to flow in a direction toward a proximal end rather than the filling balloon, when the bone filling material is supplied to the flow path. | 04-02-2015 |
20150094730 | BONE TREATMENT SYSTEM - To easily and accurately place a bone filling material in a cured state at a bone treatment target, a bone treatment system includes a placement device and a deployment operation device. The placement device includes a shaft having a flow path which enables a bone filling material to be placed on a space of a radius to flow therethrough, and a filling balloon to be filled with the bone filling material via the flow path | 04-02-2015 |
