Abstract

Aspects of the present disclosure are directed toward a medical device having a a core assembly. The core assembly includes a core circuit assembly and a core assembly housing configured to enclose the core circuit assembly. The core assembly housing includes a first portion, and a second portion configured to be coupled to the first portion along a weld seam. The second portion includes at least one weld joint feature, which includes a thinned section of the second portion.

First claim

We claim:

1. A medical device comprising:
a core circuitry assembly; and
a core assembly housing configured to enclose the core circuitry assembly, the core assembly housing comprising:
a first portion comprising:
a first side wall, the first side wall comprising a first end and a second end, wherein the first end comprises at least one notch and wherein the second end comprises at least one;
a first lower wall coupled to the first wall by a first corner portion and extending in a direction away from an inside surface of the first side wall; and
a first upper wall coupled to the first side wall by a second corner portion and extending in a direction away from the inside surface of the first side wall; and

a second portion configured to be coupled to the first portion along a weld seam, the second portion comprising;
a second side wall, the second side wall comprising a first end and a second end, wherein the first end comprises at least one notch and wherein the second end comprises at least one notch;
a second lower wall coupled to the second side wall by a third corner portion and extending in a direction away from an inside surface of the second side wall;
a second upper wall coupled to the side wall by a second corner portion and extending in a direction away from an inside surface of the second side wall; and

at least one weld joint feature, wherein the at least one weld joint feature includes a wedged-shaped section of an outside surface of the second lower wall, a wedged-shape section of an outside surface of the second upper wall, a wedged-shaped section of an inside surface of the first lower wall, and a wedge-shaped section of an inside surface of the first upper wall.

2. The medical device of claim 1 , wherein the at least one weld joint feature comprises at least one of a flange and a wedge-shaped edge of at least one wall of the second portion.

3. The medical device of claim 1 , wherein the at least one weld joint feature includes a first flange that is recessed with respect to an outside surface of the second lower wall and a second flange that is recessed with respect to an outside surface of the second upper wall.

4. The medical device of claim 3 , the at least one weld joint feature further comprising a third flange that is recessed with respect to an inside surface of the first lower wall and a fourth flange that is recessed with respect to an inside surface of the first upper wall.

5. The medical device of claim 3 , wherein the first and second flanges act as an integrated weld ring to protect the core circuitry assembly from the energy applied during a welding procedure.

6. The medical device of claim 1 , wherein the wedge-shaped section of the outside surface of the second lower wall and the wedge-shaped section of the outside surface of the second upper wall act as an integrated weld ring to protect the core circuitry assembly from the energy applied during a welding procedure.

7. A medical device comprising:
a core circuitry assembly; and
a core assembly housing configured to enclose the core circuitry assembly, the core assembly housing comprising:
a first portion comprising: (1) a first side wall, the first side wall comprising a first end and a second end, wherein the first end comprises at least one notch and wherein the second end comprises at least one; (2) a first lower wall coupled to the first side wall by a first curved corner portion and extending in a direction away from an inside surface of the first side wall; and (3) a first upper wall coupled to the first side wall by a second curved corner portion and extending in a direction away from the inside surface of the first side wall;
a second portion configured to be coupled to the first portion along a weld seam, the second portion comprising: (1) a second side wall, the second side wall comprising a first end and a second end, wherein the first end comprises at least one notch and wherein the second end comprises at least one notch; (2) a second lower wall coupled to the second side wall by a third curved corner portion and extending in a direction away from an inside surface of the second side wall; and (3) a second upper wall coupled to the side wall by a second curved corner portion and extending in a direction away from an inside surface of the second side wall; and
at least one weld joint feature, wherein the at least one weld joint feature includes a wedged-shaped section of an outside surface of the second lower wall, a wedged-shape section of an outside surface of the second upper wall, a wedged-shaped section of an inside surface of the first lower wall, and a wedge-shaped section of an inside surface of the first upper wall.

8. The medical device of claim 7 , the at least one weld joint feature includes a thinned section of the second portion that is recessed with respect to an outer surface of a wall of the second portion and a thinned section of the first portion that is recessed with respect to an inner surface of a wall of the first portion, wherein the thinned section of the second portion comprises a first flange that is recessed with respect to an outside surface of the second lower wall and a second flange that is recessed with respect to an outside surface of the second upper wall.

9. The medical device of claim 8 , wherein the thinned section of the first portion comprises a third flange that is recessed with respect to an inside surface of the first lower wall and a fourth flange that is recessed with respect to an inside surface of the first upper wall.

10. The medical device of claim 8 , wherein the first and second flanges act as an integrated weld ring to protect the core circuitry assembly from the energy applied during a welding procedure.

11. The medical device of claim 7 , wherein the wedge-shaped section of the outside surface of the second lower wall and the wedge-shaped section of the outside surface of the second upper wall act as an integrated weld ring to protect the core circuitry assembly from the energy applied during a welding procedure.
