Connector apparatus for a medical device
View Patent ↗In various examples, a connector apparatus includes at least one connector including an integral conductor and an encapsulation housing. The at least one connector includes a contact portion and a tail portion, wherein the contact portion is configured to selectively accept and electrically couple to a therapy delivery element. The tail portion extends outwardly from the contact portion. The encapsulation housing at least partially surrounds at least some of the contact portion of the conductor. The encapsulation housing includes an inner surface, wherein at least some of the contact portion of the conductor extends from the inner surface of the encapsulation housing. With a contact of the therapy delivery element disposed within the encapsulation housing, the conductor is configured to contact and electrically couple with the contact of the therapy delivery element.

4. The connector apparatus of claim 1 , wherein the connector apparatus includes more than one connector, wherein the passage of each of the connectors is generally aligned with one another along a connector apparatus axis.
5. The connector apparatus of claim 4 , comprising a connector housing engaged with the more than one connector, the connector housing configured to maintain a spacing and position of the more than one connector within the connector apparatus.
6. The connector apparatus of claim 5 , wherein the connector housing is disposed around the more than one connector.
7. The connector apparatus of claim 5 , wherein at least a portion of the connector housing is overmolded with the more than one connector.
8. The connector apparatus of claim 5 , wherein at least a portion of the connector housing is laminated over the more than one connector.
9. The connector apparatus of claim 1 , wherein the conductor is formed from a wire form including a substantially circular shape when viewed from an end.
10. The connector apparatus of claim 9 , wherein the wire form includes a wave-like pattern when flattened.
11. The connector apparatus of claim 9 , wherein the wire form includes at least two substantially U-shaped portions, each U-shaped portion extending part way around an imaginary cylinder, such that the wire form forms a substantially tubular shape.
12. The connector apparatus of claim 11 , wherein the substantially U-shaped portions are disposed in an alternating pattern, with a first substantially U-shaped portion extending in a first direction and an adjacent second substantially U-shaped portion extending in a second direction that is substantially opposite the first direction with respect to a longitudinal axis of the wire form.
13. The connector apparatus of claim 12 , wherein the first substantially U-shaped portion and the second substantially U-shaped portion are connected to each other by an integral curved connecting portion.
14. The connector apparatus of claim 12 , wherein crests of the adjacent substantially U-shaped portions extend to an imaginary axis spaced radially outwardly from a longitudinal axis of the wire form.
15. The connector apparatus of claim 1 , wherein at least a portion of the encapsulation housing is overmolded with the contact portion of the conductor.
16. The connector apparatus of claim 1 , wherein the tail portion is formed to substantially align with a device wire location, the tail portion configured to be electrically coupled to the device wire location.
17. A connector apparatus for a medical device, the connector apparatus comprising:
a plurality of connectors, each connector including:
an integral conductor including a contact portion and a tail portion, wherein the contact portion is configured to selectively accept and electrically couple to a therapy delivery element, the tail portion extending outwardly from the contact portion; and
an encapsulation housing at least partially surrounding at least some of the contact portion of the conductor, the encapsulation housing including an outer surface spaced from an inner surface, wherein at least some of the contact portion of the conductor extends inwardly from the inner surface of the encapsulation housing, and wherein, with a contact of the therapy delivery element disposed within the encapsulation housing, the contact portion of the conductor is configured to contact and electrically couple with the contact of the therapy delivery element, wherein the tail portion extends from within the encapsulation housing and outwardly past the outer surface of the encapsulation housing, and wherein the tail portion is configured to attach directly to a lead of the medical device; and
a connector housing engaged with the plurality of connectors, the connector housing configured to maintain a spacing and position of the plurality of connectors within the connector apparatus, wherein the passage of each of the plurality of connectors is generally aligned with one another along a connector apparatus axis.
18. The connector apparatus of claim 17 , wherein the connector housing is disposed around the plurality of connectors, at least a portion of the connector housing being overmolded with or laminated over the plurality of connectors.
19. The connector apparatus of claim 17 , wherein the conductor is formed from a wire form including a substantially circular shape when viewed from an end, the wire form including substantially U-shaped portions each extending part way around an imaginary cylinder, such that the wire form forms a substantially tubular shape, the substantially U-shaped portions being disposed in an alternating pattern, with a first substantially U-shaped portion extending in a first direction and an adjacent second substantially U-shaped portion extending in a second direction that is substantially opposite the first direction with respect to a longitudinal axis of the wire form.
