Abstract
Abstract Fasteners having coordinated self-seeking conforming members for implanting into a cavity such as a hole, tube, or hard tissue defect are provided. An actuator mechanism translates applied force to conform members of a plurality of members to the cavity. The fasteners may be used for implanting a prosthetic device into hard tissue of humans or animals, for anchoring a device while the device is being worked on, or for centering a device in a hole or tube, such as in well technology. The mechanism operates expanding members so that they independently or dependently conform and apply a controlled and known pressure to surrounding materials.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
135 words
A fastener for implanting into a cavity the fastener comprising: a body including a first bore formed therein; a plurality of nonbendable members movably connected to the body, each member being dependently movable for coordinated self-seeking conforming to the cavity; an actuator mechanism for coordinating and translating applied force to each member, wherein the actuator mechanism comprises a journal disposed in said first bore in said body and joined to each member by linkage operable such that when the journal is moved, each member moves dependently to conform to the cavity; and a bearing member disposed in a second bore in said body and cooperable with said body for axial movement in said second bore to move said journal and said members relative to said body to cause said members to conform to said cavity.
Claim 2
Dependent Claim
135 words
A fastener for implanting into a cavity the fastener comprising: a body including a first bore formed therein; a plurality of nonbendable members movably connected to the body, each member being dependently movable for coordinated self-seeking conforming to the cavity; an actuator mechanism for coordinating and translating applied force to each member, wherein the actuator mechanism comprises a journal disposed in said first bore in said body and joined to each member by linkage operable such that when the journal is moved, each member moves dependently to conform to the cavity; and a bearing member disposed in a second bore in said body and cooperable with said body for axial movement in said second bore to move said journal and said members relative to said body to cause said members to conform to said cavity.
Claim 3
Dependent Claim
183 words
A fastener for implanting into a cavity, the fastener comprising: a body; a first nonbendable member and a second nonbendable member movably connected to the body, each member being dependently movable for coordinated self-seeking conforming to the cavity; and an actuator mechanism for coordinating and translating applied force to each member wherein the actuator mechanism comprises a journal; a first link having a first end and a second end, the first end pivotally connected to the journal, and the second end pivotally connected to the first member; a second link having a first end and a second end, the first end pivotally connected to the journal, and the second end pivotally connected to the second member; wherein when the journal is moved, the first link and the second link move to cause the first member and the second member to move dependently to conform to the cavity; and a member engaged with said body and said journal and movable relative to said body axially in a bore in said body to cause said journal to effect movement of said first and second links.
