Abstract

A pass-through assembly including a first wall 110d having oppositely-directed inner and outer sides, 112, 114, the first wall 110d defining a first opening 116 extending from the inner side 112 to the outer side 114; an elongated structure 118 extending into the opening 116 from the outer side 114 of the first wall 110d; a first material 130 contacting the first wall 110d and the elongated structure 118 so as to at least partially seal the opening 116, and a second material 140 different from the first material 130, the second material 140 overlying the first material 130 on the outer side 114 of the wall 110d, the second material 140 adhering to the elongated structure 118 and the first wall 110d, the second material 140 having at least one physical property different than a corresponding physical property of the first material 130.

First claim

The invention claimed is:

1. A pass-through assembly comprising:
a first wall having an inner side and an outer side opposite the inner side, the first wall defining an opening extending from the inner side to the outer side and a recess in the outer side, the outer side including:
a base portion forming a floor of the recess;
an inner ring projecting outwardly from the base portion around the opening; and

an outer ring projecting outwardly from the base portion around the inner ring, the inner ring and the outer ring defining an annular space therebetween;
an elongated structure extending into the opening from the outer side of the first wall;
a ring element coupled to the elongated structure, the ring element being deformable to permit insertion into the opening in an insertion direction;
a first material contacting the first wall and the elongated structure so as to at least partially seal the opening; and
a second material disposed at least partially within the recess, overlying the first material on the outer side of the first wall and adhering to the elongated structure and the first wall, the second material including at least one physical property different than a physical property of the first material.

2. The pass-through assembly of claim 1 wherein the opening includes a diameter and the ring element defines an outer diameter greater than the diameter of the opening.

3. The pass-through assembly of claim 1 , wherein the elongated structure is flexible.

4. The pass-through assembly of claim 3 , further comprising a plurality of openings extending from the inner side to the outer side and a plurality of elongated flexible structures extending into the plurality of openings from the outer side of the first wall.

5. The pass-through assembly of claim 1 , wherein the second material covers the first material so that no portion of the first material is exposed at the outer side of the first wall.

6. The pass-through assembly of claim 1 , wherein the first material is disposed at least partially within the annular space.

7. The pass-through assembly of claim 1 , further comprising a third material disposed at least atop the second material, the third material being biocompatible.

8. The pass-through assembly of claim 7 , wherein the third material is disposed atop a surface of the housing.

9. The pass-through assembly of claim 1 , wherein the first material is a silicone.

10. The pass-through assembly of claim 1 , wherein the second material is an epoxy.

11. The pass-through assembly of claim 1 , wherein the second material is biocompatible.

12. A housing assembly comprising:
a plurality of walls defining an interior space and including a first wall having an inner side and an outer side opposite the inner side, the first wall defining an opening extending from the inner side to the outer side and a recess in the outer side, the outer side including a base portion forming a floor of the recess;
at least one inner ring disposed around the opening and at least one outer ring disposed around the inner ring, the at least one inner ring and the at least one outer ring defining an annular space therebetween, extending from the floor of the recess, and being disposed completely within the recess;
an elongated structure extending into the opening from the outer side of the first wall;
a first material contacting the first wall and the elongated structure so as to at least partially seal the opening; and
a second material overlying the first material on the outer side of the wall and adhering to the elongated structure and the first wall.

13. The housing assembly of claim 12 , wherein the second material includes at least one physical property different than a physical property of the first material.

14. The housing assembly of claim 12 , wherein the elongated structure is an electrical cable.

15. The housing assembly of claim 12 , further comprising a component mounted within the interior space, the elongated structure extending through the opening into the interior space to the component.

16. A pass-through assembly comprising:
a first wall having an inner side and an outer side opposite the inner side, the first wall defining an opening extending from the inner side to the outer side and a recess in the outer side, the outer side including:
a base portion forming a floor of the recess;
an inner ring projecting outwardly from the base portion around the opening; and
an outer ring projecting outwardly from the base portion around the inner ring,

wherein the inner ring and the outer ring define an annular space therebetween, extend upwardly from the floor of the recess and are disposed completely within the recess;
an elongated structure extending into the opening from the outer side of the first wall;
a ring element coupled to the elongated structure, the ring element being deformable to permit insertion into the opening in an insertion direction;
a first material contacting the first wall and the elongated structure so as to at least partially seal the opening; and
a second material overlying the first material on the outer side of the first wall and adhering to the elongated structure and the first wall, the second material including at least one physical property different than a physical property of the first material.
