Abstract:
A powered surgical tool (30) with a housing (32) that contains a power generating unit (34) such as a motor. A control module (40) is disposed in a shell that is mounted in the housing. The control module contains a plurality of polyimide energized active seals (79) for protecting internal components from the effects of sterilization. Also internal to the control module shell is a plurality of inner (77) and outer (76) stops, a plurality of O-rings, and a lid (60). Control module is sealed by inserting a fastener (55) through a lid opening and into a module shell post (57). O-rings (61,62) disposed between the lid and the shell also protect internal components from the effects of sterilization. Sensors (162, 168) secured to a mount internal the control module regulate the actuation of the power generating unit.
Abstract:
A method for making a feedthrough assembly (10) for an implantable electronic medical device (102) comprises providing a metallic ferrule (11) having an outer surface (12) and an aperture (13) defined by an inner lumen surface (14); providing an insulator (20), the insulator having a first surface and a second surface (18, 22). At least one of the first surface and the second surface (18, 22) of the insulator (20) includes a brazing region disposed thereon. The braze material (30) is applied to the brazing region and the insulator (20) is positioned within or around the metallic ferrule (11) such that the positioned insulator (20) brazing region and the metallic ferrule outer surface (12) or inner lumen surface (14) defines a braze gap (16, 24). The braze gap has a width ranging between 10 μm to 50 μm. The feedthrough assembly (10) is then heated at a temperature conducive to melt the braze material (30) in the braze gap (24, 16) thereby forming a hermetic seal between the ferrule (11) and said insulator (20).

A feedthrough assembly, as well as a method of forming a feedthrough assembly, including a metallic ferrule, and a biocompatible, non-conductive, high-temperature, co-fired insulator engaged with the metallic ferrule at an interface between the ferrule and the insulator. The insulator includes a first surface at the interface and a second surface internal to the insulator. At least one conductive member may be disposed at the second surface, wherein at least the first surface of the insulator is devoid of surface cracks greater than 30 µm. The first surface of the insulator may also be devoid of a surface roughness greater than 0.5 µm.
Abstract:
A base part (8, 106, 206, 306) for a compressible module for cable entries or pipe penetrations receiving one or more compressible modules surrounding each cable or pipe, which cable entries or pipe penetrations are placed either directly in an opening through a wall or other structural partition forming the wall or other partition or in a frame (1), whereby a barrier is formed of the one or more modules and at least one compression unit (3) in either the opening or the frame (1), wherein the compressible module has at least one peelable layer (9, 107, 207) for adapting to the diameter of a cable or pipe, which at least one peelable layer (9, 107, 207) is placed in a base part (8, 106, 206, 306), wherein each base part (8, 106, 206, 306) has several grooves (110, 210, 310), receiving at least one peelable layer (9, 107, 207), characterized in that the grooves (110, 210, 310) are arranged on opposing sides of the module.
Abstract:
Explosion proof enclosures and explosion proof connectors and sensors are used to render a machine, intended to be operated in an explosive environment, explosion proof. An explosion proof connector includes an intermediate section having an input portion to receive a cable from a terminal external to an explosion proof enclosure and an output portion for passing the cable for connection to a terminal within an explosion proof enclosure. A sealing tube which extends between the input and output portions has a central opening for enabling a cable to be passed through. A sealant may be injected into the sealing tube to form an air tight connection between the cable and the inner walls of the sealing tube which inhibits a hazardous condition from passing through and around the sealing tube. An explosion proof sensor includes potting and encasing the sensor in its own explosion proof case.
Abstract:
A device for electric connection to an energy supply conductor (11) for medium and high voltage, comprising: a voltage-carrying element (2); a tubular outer shell (3) formed by a thermoplastic polymer and connected to the voltage carrying element (2); wherein the voltage-carrying element (2) extends in a longitudinal direction of said tubular shell (3), and wherein, at least along a part of the length of the voltage-carrying element (2), the outer shell (3) extends in said longitudinal direction with a space ( 102) between its inner periphery and an outer periphery of the voltage- carrying element (2); said outer shell (3) being provided with an outer contact surface (101) to be connected to a wall (7) of a gas-tight container somewhere along said part of the length of the voltage-carrying element (2); wherein said outer shell (3) is arranged so as to separate said space (102) from an atmosphere outside a container to which said device may be connected. At least along a section of said part of the length of the voltage-carrying element (2) said space (102) is filled with a filler (103) of an electrically insulating material other than that of the outer shell (3), said filler ( 103) completely filling said space (102) along said section.

Abstract:
A hermetic or semi-hermetic terminal assembly having a cup-shaped body portion with a generally flat bottom wall and at least one opening in the bottom wall defined by an annular lip extending into the cup. One current conducting pin extends through each opening and beyond the lip on both ends of the body portion, the inner end of the pin being on the dish side of the cup-shaped body portion, and the outer end on the outer side of the body. A resilient plastic material is molded into place within the body portion to bond the pin to an inside surface of the lip with a hermetic seal. The plastic extends beyond the face of the body portion and bonds to the pin to provide the desired air path between the respective pins and each other and/or the face of the body portion.
