Apparatus and method for attaching soft tissue to bone
First Claim
1. Apparatus for attaching tissue to bone comprising:
- an expandable body configured to expand into bone, said expandable body comprising a distal tip member and a proximal main member, said distal tip member being separable from said main proximal main member, and said expandable body defining a bore extending therethrough from a proximal end of the proximal main member to a distal end of the distal tip member; and
an expander pin comprising a shaft sized to be received in the bore of said expandable body and expand said proximal main member laterally when said expander pin is driven into said proximal main member;
whereby when said expander pin is driven into said proximal main member such that said expander pin passes through said proximal main member before arriving at said distal tip member, said expandable body is attached to the bone;
wherein said apparatus further comprises an installation tool, and wherein said installation tool comprises a shaft sized to be slidingly received in said bore of said expandable body and a bore of said expander pin.

Abstract
Apparatuses for attaching tissue to bone are provided. In one exemplary embodiment, the apparatus includes an expandable body defining a bore, an expander pin having a shaft sized to be received in the bore of the expandable body, and an insertion shaft slidingly disposed in the bore of the expandable body and in a bore of the expander pin. The body is configured to expand laterally into and attach to bone when the expander pin is driven into the expandable body. The body includes a proximal main member having a distally extending threaded projection and a harder, distal tip member having a threaded recess in a proximal surface thereof such that the projection is threadedly interengageable with the recess. The expansion of the body by way of the pin can occur when the proximal main member and distal tip member are threadedly engaged. The insertion shaft is releasably secured to the expandable body and extends distally beyond the expandable body.
