  • Patent number: 8277227
    Abstract: A method (10) of forming an electrically conducting feedthrough. The method (10) comprises a first step (11) of forming an electrically conductive structure (21) comprising a sacrificial component and a non-sacrificial component. At least a portion of the non-sacrificial component can then be coated with a relatively electrically insulating material (35) prior to removal of at least a portion of the sacrificial component from the electrically conductive structure. The structure of the feedthrough provides electrical connection through the wall of a housing of an implantable component while preventing unwanted transfer of materials between the interior of the component and the surrounding environment.

  • Patent number: 8267708
    Abstract: An implantable connector electrically connects multi-conductor leads to an implantable medical device such as a neurostimulator. The connector is applicable to a variety of lead contact terminals, including iso-diametric terminals with ring contacts, paddle-shaped terminals with flat pad contacts, and orthogonal lead contact terminals. The connector is assembled directly into a hermetic feedthrough of the device and utilizes the feedthrough housing as a sustaining structure for connector pressurization. The feedthrough pins are integrated with compressible contacts in a manner that confines, protects, and precisely positions the compressible contacts. The compressible contacts can be coil springs, metal-particle-filled elastomer buttons, and fuzz buttons, and can be used with rigid tips where a contact preload and/or an enhanced contact tip robustness is desired.

Additional features include a feedthrough where pins exiting a housing of the implantable medical device extend into the header to make direct electrical connection to electrical contacts present within the header where those electrical contacts directly engage electrical connectors of leads inserted into the header. Other features include electrical contacts that are relatively thin conductors on the order of 0.040 inches or less and may include radial protrusions where the radial protrusions establish contact with the electrical connectors of the lead. Furthermore, electrical contacts may be mounted within the header in a floating manner so that radial movement of the electrical contact may occur during lead insertion.

  • Patent number: 7942686
    Abstract: Multiple seals, internal to a connector block, provide for connecting an implantable medical device and an implanted cable or lead. The forces to engage sealing or releasing the seals are derived from a mechanism so they can be relaxed to permit ease of insertion or withdrawal of a lead, or can be increased to tightly seal against fluid migration, and to provide an electrical insulation between adjacent conductors of the lead and connector block. During implant of the medical device, the lead is inserted and a shaft is rotated with a tool to engage the seals. Later, the seals can be released by rotating the control shaft in the opposite direction to allow extraction of the lead from the connector block. The seals therefore are able to provide improved sealing without increasing the insertion or the extraction forces for the lead.

    Abstract: An apparatus, system, and method are disclosed for creating an electrical connection with an electrically conductive element. The apparatus includes a first contact element having an engagement surface for engaging a first side of the electrically conductive element and a second contact element positioned opposite the first contact element includes an opposing engagement surface for engaging a second side of the electrically conductive element. The first contact element is slideable past the second contact element to form a scissor-like jaw. A valley formed in at least one of the engagement surface and the opposing engagement surface of the first and second contact elements creates a stage. At least one of the first and the second contact elements are made of an electrically conductive material that conducts an electrical current between the electrically conductive element and at least one of the first and second contact elements.

  • Patent number: 7899549
    Abstract: Cardiac lead implantation systems and methods including an electronics arrangement provided with a user interface and a coupler assembly. A coupler body is configured to detachably grasp a cardiac lead and couple with electrical contacts of the cardiac lead. A user interface includes an output indicative of sensed cardiac parameters, such as one or both of cardiac signal amplitude and lead electrode impedance, and may include an audio output device and/or a visual output device. Methods of lead implantation involve advancing a cardiac lead into proximity with a patient's heart, and contacting cardiac tissue with an electrode arrangement to locate a suitable implant location. Sensing of one or more cardiac parameters is accomplished and an audible representation of the sensed parameters is produced, the audible representation varying as the electrode arrangement is moved relative to the cardiac tissue.

  • Patent number: 7798862
    Abstract: An electrical connection assembly of a medical device includes a plurality of electrical contact blocks and a sealing member, which are held within a cavity of a base of the assembly. The sealing member includes a plurality of openings, at least one interior surface surrounding a bore and at least one void. Each electrical contact block extends into a corresponding opening of the sealing member, and a conductive sidewall of each block defines a portion of a perimeter of an area for receiving a lead connector, while the bore of the sealing member forms another portion of the perimeter of the area. The at least one void provides a compressible space in a bulk volume of the sealing member. When the lead is inserted within the area, and a cap is engaged with the base, the at least one interior surface of the sealing member is compressed about the lead.

  • Patent number: 7794256
    Abstract: An implantable connector electrically connects multi-conductor leads to an implantable medical device such as a neurostimulator. The connector is assembled directly into a hermetic feedthrough of the device and utilizes the feedthrough housing as a sustaining structure for connector pressurization. The feedthrough pins are adapted to directly connect, confine, protect, and precisely position respective resilient compressible contacts. The compressible contacts can be coil springs, metal-particle-filled elastomer buttons, and fuzz buttons, and can be used with rigid tips where a contact preload and/or an enhanced contact tip robustness is desired. In one method of connector assembly an iso-diametric lead proximal terminal is first inserted into a seal without significant interference, and the resulting lead-seal assembly is subsequently installed in a clamping cover.

  • Patent number: 7758369
    Abstract: A plug connector for use with a receptacle. The plug connector and receptacle combination may prevent more than one use of the single use plug connector, thereby necessitating disposal of the plug connector and associated, disposable, specialized instrumentation to which the plug connector is connected. The plug connector may be keyed and otherwise identified to the receptacle by shape, tactile indicia and visual indicia so that it cannot be mistakenly used with a different receptacle, while providing proper orientation for rapid assembly. When designed for single use or limited multiple use, the insertion of the plug connector into the receptacle moves a jumper contact in the plug connector from a first position to a second position where it is captured.

  • Patent number: 7740510
    Abstract: An electrode clamp (10; 100) for making contact with a film electrode and a snap electrode has a first part (12; 112), a second part (14; 114), and a contact element (60; 160). For clamping a film electrode, the two parts (12, 14; 112, 114) can be pivoted toward one another. In an initial state of the electrode clamp (10; 100), the first part (12; 112) and the second part (14; 114) have an offset (36; 136) relative to one another. The offset can be reduced by movement of the second part (14; 114) relative to the first part (12; 112) to such an extent that the snap electrode can be inserted into the electrode clamp. By a reset motion of the second part (14; 114) relative to the first part (12; 112) in the direction of the initial state, the snap electrode can be clamped against the contact element (60; 160) and contact can be made with the snap electrode. The electrode clamp (10; 100) can be connected in a mechanically detachable manner to the snap electrode.
