A medical guide wire ( 1 ) has a helical spring body ( 3 ), a distal end portion of which has a radiopaque helical portion ( 31 ), and an elongate core ( 2 ) placed within the helical spring body ( 3 ). The elongate core ( 2 ) has a distal end portion ( 21 ) diametrically thinned and having a proximal end portion ( 22 ) diametrically thickened. A securement portion ( 10 ) is provided in which the distal end of the helical spring body ( 3 ) and the distal end of the elongate core ( 2 ) are air-tightly bonded. A floatage chamber ( 5 ) is formed within the radiopaque helical portion ( 31 ). A synthetic resin layer ( 4 ) coated on an outer surface of the helical spring body ( 3 ) forms a cylindrical film ( 43 ) at a clearance (C) between neighboring coil lines of the helical spring body ( 3 ) in a condition that an outer diameter of the cylindrical film ( 43 ) is smaller than that of the helical spring body ( 3 ) when expanding the helical spring body ( 3 ) in the moistened condition, thus enabling an operator to a deep insertion against a blood vessel due to a buoyance and an increased pressure resistance caused by blood streams.

An electrode array design is provided which is intended for deep insertion into a human cochlea. The distal most portion of the lead can be very thin and flexible and have a wider arc than the remainder of the curved electrode array portion of the lead, which has a more aggressive arc. As a result, the distal most portion of the electrode array can be laterally positioned in a selected cochlear duct, whereas, concurrently, the remaining, more proximal part of the electrode array may be positioned medially (perimodiolar) within the cochlear duct.

An oral care implement comprises a head portion and handle portion comprising resiliently folding appendages. The appendages extend laterally outwards from a central body of the handle portion in opposite directions. In one embodiment, the appendages may each have annular loop structures with recurvant ends coupled to the body. The head portion comprises tooth cleaning elements such as bristles. The head portion, handle portion, and bristles may be a monolithic construction of a resiliently deformable material with elastic memory. The bristles may be especially pliable and adapted for infant or toddler use. The appendages have an undeformed width preventing the young child from over-insertion into the oral cavity when at maximum span. The appendages may be folded against the body for deeper insertion into the oral cavity by an adult. The implement is configured to prevent the head portion and tooth bristles from contacting a flat surface when placed thereon.

The invention discloses a positioning socket type pipe joint structure. The structure comprises a bearing port and an inserting port in insertion matching of pipe fittings; a sealing ring is arranged between the bearing port and the inserting port; a positioning ring is peripherally arranged on the outer wall of the pipe fitting near the inserting port; the outer diameter of the positioning ring is larger than the inner diameter of the bearing port; and the distance from the end part of the inserting port to the positioning ring is smaller than the depth of the bearing port. When multiple pipe fittings are connected end to end to form the pipe, as the positioning ring is arranged on the outer wall of the pipe fitting near the inserting port, the collision phenomenon between the end part of the inserting port and the bottom of the bearing port caused by deep insertion in the inserting port has no need to worry about, the insertion construction requirements can be simplified to a certain extent, and the purposes of accelerating the connecting speed of the pipe fittings, accelerating the construction progress, shortening the construction period and saving the construction cost are achieved; and meanwhile, the wear or damage phenomenon of the inner walls of the pipe fittings and corrosion-resistant layers caused by collision between the end part of the inserting port and the bottom of the bearing port is eliminated, so that the normal service life of the pipe is guaranteed.

In accordance with the present invention, there is provided a technique which may be used in conjunction with an automated Z-pin insertion process to automatically monitor the insertion energy applied to the Z-pins during the initial insertion phase of the automated insertion process, and compare it to an empirically derived value for good insertions, thereafter allowing the insertion process to continue to a predetermined additional insertion depth before terminating the process. The insertion energy is calculated by cumulatively summing the insertion force and multiplying it by the insertion time, thus yielding the cumulative energy. At a specified, predetermined insertion depth, the energy accumulation is stopped and the value at the initial insertion depth is stored and compared to an empirically derived value. If the value is less than the empirical value, the insertion energy is too low, thus indicating that either a partial grid insertion is being encountered or defective Z-pins are being inserted. Insertion is allowed to continue until another empirically derived second insertion depth is reached whereat the insertion is terminated. The second depth is necessary for the continued insertion of partial grids to ensure that the Z-pins are fully inserted. The second depth is a function of the laminate thickness to ensure full depth insertions.
