Abstract

A spacer member is provided that is configured to be implanted adjacent an anatomical structure. The spacer member defines a curved bore, a first opening in a side wall of the spacer member and a second opening in one of a top wall and a bottom wall of the spacer member. Each of the first opening and the second opening are in fluid communication with the curved bore. A flexible anchoring member is configured to be inserted through the side opening and through the curved bore of the spacer member such that a distal end portion of the flexible anchoring member extends out of the second opening at an angle relative to the one of the top wall and the bottom wall of the spacer member.

First claim

What is claimed is:

1 . A medical device, comprising:
an expandable fusion member configured to be inserted while in a collapsed configuration into a portion of a vertebra of a patient, the expandable fusion member having a first portion and a second portion and defining an interior region configured to receive an inflation medium to move the expandable fusion member from the collapsed configuration to an expanded configuration while disposed within the vertebra, when in the expanded configuration, the first portion of the expandable fusion member extends within a first bore within a portion of the vertebra, and the second portion extends within a second bore within a portion of the first vertebra.

2 . The medical device of claim 1 , wherein the vertebra is a first vertebra, the first portion of the expandable fusion member is configured to self-locate within the first bore in the first vertebra, the second portion of the expandable fusion member is configured to self-locate within the second bore in the first vertebra, a bore in an intervertebral disc and into a bore in a second vertebra when moved to its expanded configuration.

3 . The medical device of claim 1 , wherein the first portion of the expandable fusion member includes a textured portion configured to promote engagement between the first portion of the expandable fusion member and a portion of tissue within the vertebra.

4 . The medical device of claim 1 , further comprising:
an elongate member removably disposable within the interior region of the fusion member, the elongate member being formed with a shape-memory material and having a collapsed configuration when inserted into the interior region of the expandable fusion member and being movable to an expanded configuration when the expandable fusion member is moved to its expanded configuration, the elongate member being biased to its expanded configuration.

5 . The medical device of claim 1 , further comprising:
an elongate member having a first portion and a second portion and disposable within the interior region of the expandable fusion member, the first portion of the elongate member configured to be disposed within the portion of the interior region associated with the first portion of the expandable fusion member, the second portion of the elongate member configured to be disposed within the portion of the interior region associated with the second portion of the expandable fusion member.

6 . The medical device of claim 1 , further comprising:
an insertion tool configured to be removably coupled to the expandable fusion member, the insertion tool configured to inject the inflation medium into the interior region of the expandable fusion member.

7 . The medical device of claim 1 , wherein the inflation medium is a curing agent.

8 . A medical device, comprising:
a first elongate member defining a lumen between a proximal end portion and a distal end portion of the first elongate member; and a second elongate member movably disposable within the lumen of the first elongate member, the second elongate member being flexible and including a at least one cutting member disposed on an outer surface of a distal end portion of the second elongate member, the first elongate member configured to restrain the second elongate member in a substantially linear configuration when disposed within the lumen of the first elongate member, the second elongate member being movable to a biased curved configuration when disposed outside of the lumen of the first elongate member, a distal end portion of the first elongate member configured to be inserted into an anatomical structure of a patient when the distal end portion of the second elongate member is disposed within the lumen of the first elongate member, the distal end portion of the second elongate member configured to cut tissue within a portion of the anatomical structure along a non-linear path when the second elongate member is moved distally relative to the first elongate member such that the distal end portion of the second elongate member extends outside of the lumen of the first elongate member and is moved to its curved configuration and the second elongate member is rotated.

9 . The medical device of claim 8 , further comprising:
a third elongate member coupled to the second elongate member, the third elongate member formed with a shape-memory material and having a biased curved shape, the third elongate member configured to move the distal end portion of the second elongate member from its substantially linear configuration to its curved configuration.

10 . The medical device of claim 8 , wherein the anatomical structure is a portion of a spine of the patient.

11 . The medical device of claim 8 , wherein the anatomical structure is a first anatomical structure, the distal end portion of the second elongate member being configured to cut tissue within a portion of the first anatomical structure and a portion of a second anatomical structure adjacent the first anatomical structure along a non-linear path when the second elongate member is moved distally relative to the first elongate member such that the distal end portion of the second elongate member extends outside of the lumen of the first elongate member and is moved to its curved configuration and the second elongate member is rotated.

12 . The medical device of claim 8 , wherein the distal end portion of the first elongate member configured to be inserted into a pedicle of a vertebra of the patient, the distal end portion of the second elongate member configured to cut tissue within a portion of the vertebra along a non-linear path when the second elongate member is moved distally relative to the first elongate member such that the distal end portion of the second elongate member extends outside of the lumen of the first elongate member and is moved to its curved configuration and the second elongate member is rotated.
