Tissue retractor stay
A surgical stay includes an elastomeric elongated member having a first closed end and a second end and a tissue retention member coupled to the first end thereof. The tissue retention member extends outwardly from the first end of the elongated member. A substantial portion of the length of the elongated member is hollow. The elongated member and the tissue retention member are integrally molded so that no openings are present therebetween.
1. A surgical stay comprising:
an elastomeric elongated member having a first end and a second end, wherein a portion of a length of the elongated member comprising the first end comprises a solid cross-section and another portion of the length of the elongated member comprises a hollow cross-section; and
a tissue retention member coupled to and directly contacting the first end of the elastomeric elongated member, the tissue retention member comprising an anchor portion and a tissue engaging portion, wherein the anchor portion connects directly into the first end such that the anchor portion extends into and is secured within the solid cross-section of the elastomeric elongated member, and wherein the tissue engaging portion extends outwardly from the first end.
2. The surgical stay of claim 1 , wherein the elongated member includes a plurality of hubs positioned at spaced locations along at least part of the length of the elongated member.
3. The surgical stay of claim 2 , wherein the anchor portion is positioned at least in part inside one of the hubs of the elongated member.
4. The surgical stay of claim 1 , wherein the surgical stay is formed by injection molding of the elongated member with the tissue retention member.
5. The surgical stay of claim 1 , wherein the elastomeric elongated member is made of silicone.
6. The surgical stay of claim 1 , wherein the tissue engaging portion has at least one hook, the hook is at least one of a sharp hook and a blunt hook, and the anchor portion is at least one of a coiled portion, a loop, a projection, a bulb, a barb, and a bent element.
7. The surgical stay of claim 1 , wherein the other portion of the length of the elongated member comprising the hollow cross-section extends along at least one-half of the length of the elongated member and has a substantially cylindrical shape.
8. The surgical stay of claim 1 , wherein the elongated member has a substantially cylindrical shape.
9. A surgical stay comprising:
an elongated member having a hollow portion along at least a portion of its length and a solid portion along at least another portion of its length, wherein the elongated member includes a plurality of integral hubs positioned at spaced locations along at least part of its length; and
a tissue retention member coupled directly in to one end of said elongated member, wherein the tissue retention member includes an anchor portion and a tissue engaging portion, the anchor portion extends directly into the solid portion of the elongated member and is positioned inside at least one of the plurality of hubs, and the tissue engaging portion extends from the one end of the elongated member, and
wherein the surgical stay is formed by injection molding of the elongated member with the tissue retention member.
10. The surgical stay of claim 9 , wherein the elongated member is made of an elastomeric material.
11. The surgical stay of claim 9 , wherein the elongated member is made of silicone.
12. The surgical stay of claim 9 , wherein the tissue retention member has at least one hook and the hook is at least one of a sharp hook and a blunt hook.
13. The surgical stay of claim 9 , wherein the anchor portion is at least one of a coiled portion, a loop, a projection, a bulb, a barb, and a bent element.
14. The surgical stay of claim 9 , wherein the hollow portion extends along at least one-half of the length of the elongated member.
15. The surgical stay of claim 9 , wherein the hollow portion has a substantially tubular, cylindrical shape.
16. The surgical stay of claim 9 , wherein the elongated member is substantially cylindrical.
17. The surgical stay of claim 9 , wherein the anchor portion extends into more than one of the plurality of hubs.
18. A surgical stay comprising:
an elastomeric elongated member having a first end and a second end, wherein a portion of a length of the elongated member comprising the first end comprises a solid cross-section and another portion of the length of the elongated member comprises a hollow cross-section, wherein the elastomeric elongated member includes a plurality of integral hubs positioned at spaced locations along at least part of the length of the elastomeric elongated member; and
a tissue retention member directly integrated into the first end of the elastomeric elongated member, the tissue retention member comprising an anchor portion and a tissue engaging portion, wherein the anchor portion connects directly into the first end such that the anchor portion extends into and is secured within the solid cross-section and at least one of the plurality of hubs, and wherein the tissue engaging portion extends outwardly from the first end.
19. The surgical stay of claim 18 , wherein the tissue engaging portion has at least one hook, the hook is at least one of a sharp hook and a blunt hook, and the anchor portion is at least one of a coiled portion, a loop, a projection, a bulb, a barb, and a bent element.
