An embolic coil configured with a self-adaptive floating diameter in a relaxed condition substantially assuming the shape of the inner surface of the vessel at the site of an embolization procedure. The embolic coil comprises a distal end having an anchoring loop for anchoring at the site, a proximal end with a loop for detaching from a gripper assembly adapted to deliver to the site, a primary framing coil formed of a plurality of primary omega curves extending between the proximate and distal ends, and a secondary filling coil arrangement formed from a plurality of secondary omega curves that follow the trajectory of the plurality of primary omega curves along the longitudinal length of the embolic coil between the proximate and distal ends. The embolic coil conforms to the diameter of the aneurysm sac enabling retractability and rapid disconnect detachment for such embolic coil advantageously requiring fewer embolic coils.

Self-adapting floating diameter embolic coil

The present invention relates to a spring to return more quickly the jaws of a gripper assembly of a delivery system for deploying an embolic coil. Each of the jaws and spring are formed of shape memory alloy configured to be movable between a first position and a second position and returning to the first position, with the spring tension increasing the speed of the return to the first position of the jaws of the gripper assembly. The gripper assembly may be used to insert, retract, reconnect, and rapidly disconnect from the embolic coil.

Spring for moveable jaws of device and delivery system for releasing therapeutic appliance

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.

Visual indicator of proper interconnection for an implanted medical device

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.

Electrical connection apparatus

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

An electrical connection apparatus includes at least one stackable block operably coupleable to another stackable block, at least one pin receiving portion defined by an inner wall within the stackable block, and at least one electrical connection contact having a C-shaped contact portion with elastic properties disposed within the pin receiving portion and a lead portion disposed at a location exterior to the stackable block. The electrical connection apparatus may further include an adjustment component and an adjustment component receiving portion defined by in inner wall within the stackable block. In addition, sliders may be arranged on the stackable block and may engage with tabs formed on the at least one electrical connection contact. The sliders may be moved to a raised or lowered position in order to move the at least one electrical connection contact between a contact and an insertion position.
