1. An implant, comprising:
- a body having a leading edge portion, a trailing edge portion, and an intermediate portion extending between the leading edge portion and the trailing edge portion, the body having a central axis extending from the leading edge portion to the trailing edge portion;
wherein the leading edge portion includes a substantially smooth surface forming a substantial majority of a leading edge surface of the leading edge portion;
wherein the trailing edge portion includes a monolithic structure including at least one receptacle configured to receive an insertion tool;
wherein the intermediate portion includes a plurality of elongate curved structural members;
wherein the plurality of elongate curved structural members includes one or more spiral members continuously formed with at least one of the leading edge portion and the trailing edge portion;
wherein the one or more spiral members are configured such that the intermediate portion remains substantially rigid under compressive forces during insertion of the leading edge portion between bone surfaces of a patient;
wherein at least one spiral member of the one or more spiral members has a central axis extending along a length of the spiral member; and
wherein the central axis of the at least one spiral member is offset from the central axis of the body.

Abstract
An implant includes a body having a leading edge portion, a trailing edge portion, and an intermediate portion extending between the leading edge portion and the trailing edge portion. The leading edge portion includes a substantially smooth surface forming a substantial majority of a leading edge surface of the leading edge portion. The trailing edge portion includes a monolithic structure including at least one receptacle configured to receive an insertion tool. In addition, the intermediate portion includes a plurality of elongate curved structural members.

12. An implant, comprising:
-
a body having a leading edge portion, a trailing edge portion, and an intermediate portion extending between the leading edge portion and the trailing edge portion; wherein the leading edge portion includes a substantially smooth surface forming a substantial majority of a leading edge surface of the leading edge portion; the leading edge portion having an elongate configuration extending from a first end to a second end; wherein the trailing edge portion includes a monolithic structure including at least one receptacle configured to receive an insertion tool; the trailing edge portion having an elongate configuration extending from a first end to a second end; and further including at least one elongate substantially spiral member extending from the first end of the leading edge portion to the first end of the trailing edge portion, thereby forming a perimeter portion of the implant extending between the leading edge portion and the trailing edge portion; wherein the at least one elongate substantially spiral member is configured such that the intermediate portion remains substantially rigid under compressive forces during insertion of the leading edge portion between bone surfaces of a patient, so as to maintain spacing and orientation of leading edge portion and trailing edge portion with respect to one another during insertion. - View Dependent Claims (13, 14, 15, 16)

17. An implant, comprising:
-
a body having a leading edge portion, a trailing edge portion, and an intermediate portion extending between the leading edge portion and the trailing edge portion; wherein the leading edge portion includes a substantially smooth surface forming a substantial majority of a leading edge surface of the leading edge portion; the leading edge portion having an elongate configuration extending from a first end to a second end; wherein the trailing edge portion includes a monolithic structure including at least one receptacle configured to receive an insertion tool; and the trailing edge portion having an elongate configuration extending from a first end to a second end; at least one support beam extending between the leading edge portion and the trailing edge portion; and at least one elongate substantially helical member extending from the first end of the leading edge portion to the first end of the trailing edge portion, thereby forming a perimeter portion extending between the leading edge portion and the trailing edge portion; wherein the at least one elongate substantially helical member is configured such that the intermediate portion remains substantially rigid under compressive forces during insertion of the leading edge portion between bone surfaces of a patient. - View Dependent Claims (18, 19, 20)
