Various aspects of the present disclosure are directed toward an implantable electrostimulation device, a plurality of sensing and pacing elements, and a fine wire lead extending in a sealed relationship from the electrostimulation device and to the plurality of sensing and pacing elements. The fine wire lead includes multiple discrete conductors and a drawn silica or glass fiber core, a polymer cladding on the drawn silica or glass fiber core, and a conductive metal cladding over the polymer cladding. Additionally, the fine wire lead simultaneously delivers different electrical signals or optical signals between the sensing and pacing elements and the electrostimulation device.

Optical fiber-fine wire lead for electrostimulation and sensing

A multiple contact connector interfaces between an implanted medical device and an implanted cable or lead. A connector connects between multiple implanted leads, each of which has multiple independent conductors. The connection system is a planar array of male connector pins on one portion, and a matching array of female connector receptacles on a second portion. Alignment via alignment features and pressing together the portions allows pins to engage with the receptacles providing a secure electrical connection. Sealing features on the connector apparatus seal out external fluids and isolate fluid present in the connector apparatus prior to mating, which electrically isolates each pin and its corresponding receptacle from other pin and receptacle pairs. Latching features retains the relative position of the pins, receptacle, and the positioning of the fluid seals, and is reversible for removal of the connector.

Electrical connection system and method for implantable medical devices

During implant of an implantable medical device, implanted cables or leads are inserted to a connector block. An insertion indicator provides the user with a visual indication the cables or leads have been correctly inserted into the connector block, which enables the implanted medical device to properly deliver treatment or receive signals via the implanted cables or leads. The insertion indicator may be provided by a mechanical indicator optically viewable once the lead has been correctly inserted, and/or may be provided by an electrically activated light indicator illuminated by a power source associated with the connector block or with a connector tool used to connect the lead or cable to the connector block upon correct insertion of the lead or cable. The insertion indicator may be permanently or removably disposed on the connector block, a connector tool, and/or a can associated with the connector block.

An electrical connection apparatus includes an electrical connection contact and an adjustment component within an interior of the electrical connection apparatus. The electrical connection contact is operatively coupled to the adjustment component so that the electrical connection contact adjusts between an insertion position and a contact position in response to rotating the adjustment component. A slider movably arranged within the interior of the electrical connection apparatus causes the electrical connection contact to move in response to rotation of the adjustment component. The electrical connection apparatus includes one or more blocks, and the adjustment component, electrical contact and slider are arranged within an interior of the one or more blocks.

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.

Electrical barrier and moisture seal for an implanted medical device

A marginal oil extraction system having an upper extraction unit, an extraction container, and a lower valve assembly. The marginal oil extraction system uses at least some of these components to cheaply extract oil from a stripper oil well. In some cases the system is capable of separating the oil from the water in the well with a solid barrier and can cheaply remove the oil from above the solid barrier. The system is cheap to install, easy to maintain and provides efficient access to what would otherwise be an inaccessible asset.
