An interconnected printhead die and carrier substrate system for a printhead in hard-copy-producing devices used to print on print media includes a printhead die and a carrier substrate. The die and the substrate are coupled and each has an operative face separated from an inner face, and includes integrated circuits formed therein. At least three spacers are positioned between the die and substrate to define a space that is filled with an adhesive/under-fill layer. An electrical-connection region is located adjacent the inner faces of the die and substrate, and is effective to accommodate bilateral communication between integrated circuits formed on the die and the substrate. The die and the substrate may also have a stepped shape, and a cavity is formed by the stepped die and stepped substrate, with the electrical-connection region being located in the cavity. The electrical-connection region is also encapsulated with an encapsulant that may fill the cavity.

An apparatus and method of fabricating a flextensional transducer capable of ejecting a flowable material is disclosed. The method of fabricating a flextensional transducer capable of ejecting a flowable material includes ultrasonically metal welding an actuator body having an outer diameter and an aperture to a transducer membrane having an outer diameter and an aperture. The transducer membrane is also ultrasonically metal welded to a gland or nozzle capable of housing a portion of the flowable material. The gland or nozzle includes a surface adjacent to the transducer membrane having an aperture. The outer diameter of the actuator body is smaller than the aperture of the gland or nozzle.

A printhead used to eject fluid onto a recording medium has an integrated heat-sink which is used to cool the energy dissipation elements used to propel the fluid from the printhead. The printhead is comprised of a semiconductor substrate that has been processed with thin-film layers. On top of the thin-film layers is an orifice layer that has a pattern of orifices. Fluid feed channels, on the side of the printhead opposite the orifice, supply fluid to the pattern of orifices. Within the thin-film layers are energy dissipating elements which are used to transfer energy to the fluid thereby ejecting fluid from the orifice. The fluid is transferred to the orifice opening through fluid feed slots formed in the thin-film layer adjacent to the energy dissipation elements which is exposed in the fluid feed channel. An integrated heat-sink is attached to the energy dissipation elements to remove heat to the semiconductor substrate and the fluid supply in the fluid feed channel.

A method for forming a cochlear electrode array with a plurality of electrodes which are spaced so as to stimulate sites within a cochlea includes shaping a sheet of electrically conductive material to form a support structure and a plurality of electrodes, in which the electrodes are tethered to the support structure at the spacing of the cochlear electrode array. A cochlear lead includes a flexible body that has frictional characteristics that vary about its circumference. A cochlear lead includes a flexible body with a first region and a second region with different surface textures. This generates differential sliding forces during insertion of the cochlear lead which influence a motion of the cochlear lead during insertion. The cochlear lead having an electrode array with varying stiffness along its length is also provided.

Exemplary insertion tools, systems, and methods for inserting an electrode array portion of a lead into a bodily orifice are described herein. An exemplary insertion tool includes a handle assembly, a slider assembly, a retractor assembly disposed at least partially within the handle assembly, and a rocker lever. The retractor assembly may include a stiffening member configured to be inserted into the electrode array portion and a spring-loaded retractor member coupled at a proximal end of the stiffening member. The spring-loaded retractor member may be configured to move from a distal position to a proximal position to at least partially retract the stiffening member from the electrode array portion. The rocker lever may be configured to selectively retain the spring-loaded retractor member in the distal position. Corresponding tools, systems, and methods are also described.

Exemplary insertion tools, systems, and methods for inserting a pre-curved electrode array portion of a lead into a bodily orifice are described herein. An exemplary insertion tool includes a handle assembly, a slider assembly, an insertion assembly coupled to the handle assembly, and a retractor assembly disposed at least partially within the handle assembly and configured to selectively couple to a straightening member inserted into the pre-curved electrode array portion and at least partially retract the straightening member from the pre-curved electrode array portion in response to actuation by a user of the slider assembly. The retractor assembly may comprise a spring-loaded retractor member configured to move from a distal position to a proximal position in response to actuation by the user of the slider assembly to at least partially retract the straightening member from the pre-curved electrode array portion. Corresponding insertion tools, systems, and methods are also described.
