1. A bone implant, comprising:
- an elongated hollow member; and
a tip member having a longitudinal axis, wherein the tip member comprisesa distal portion that tapers from proximal to distal, wherein the distal portion has a first dimension transverse to the longitudinal axis that is maximum at its proximal end and wherein the distal portion is configured to pierce through bone,a middle portion having a second dimension transverse to the longitudinal axis that is constant along the middle portion'"'"'s length, wherein the middle portion comprises a suture aperture, anda proximal portion having a third dimension transverse to the longitudinal axis that is constant along the proximal portion'"'"'s length and smaller than the second dimension, wherein the proximal portion is configured to be positioned within a distal portion of the elongated hollow member and not extend to a proximal end of the elongated hollow member,wherein the tip member has a length that is shorter than the length of the elongated hollow member, andwherein the elongated hollow member has an inner dimension transverse to its length that is smaller than the maximum first dimension.

Abstract
Methods and devices for securing soft tissue to a rigid material such as bone are disclosed herein. A bone anchor is described that comprises a base and a top such that suture material may be compressed between surfaces on the base and top to secure the suture to the anchor. Also described is an inserter that can be used to insert the bone anchor into bone and move the anchor top relative to the anchor base to clamp suture material there between. Also described is a soft-tissue and bone piercing anchor and associated inserter. Methods are described that allow use of the bone anchors to provide multiple lengths of suture material to compress a large area of soft tissue against bone.

9. An inserter and bone implant combination, comprising:
-
an inserter, comprising; a handle, an outer sleeve coupled to the handle, and an inner tube disposed within the outer sleeve; and a bone implant coupled to the inserter, the bone implant comprising; an elongated hollow member, and a tip member having a longitudinal axis, wherein the tip member comprises; a distal portion that tapers from proximal to distal, wherein the distal portion has a first dimension transverse to the longitudinal axis that is maximum at its proximal end and wherein the distal portion is configured to pierce through bone, a middle portion having a second dimension transverse to the longitudinal axis that is constant along the middle portion'"'"'s length, wherein the middle portion comprises a suture aperture, and a proximal portion having a third dimension transverse to the longitudinal axis that is constant along the proximal portion'"'"'s length and smaller than the second dimension, wherein a portion of the inner tube extends distally through the elongated hollow member and contacts the tip member, wherein the proximal portion of the tip member is configured to be positioned within a distal portion of the elongated hollow member and not extend to a proximal end of the elongated hollow member and is removably coupled to the inserter, wherein the length of the tip member is shorter than the length of the elongated hollow member, wherein the elongated hollow member has an inner dimension transverse to its length that is smaller than the maximum first dimension, and wherein a distal end of the outer sleeve is flush with an open, proximal end of the elongated hollow member. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
