1. A suture anchor for securing suture to soft bone, comprising:
- a central body having a central axis, a distal end and a proximal end; and
a continuous thread for anchoring the suture anchor in soft bone, the continuous thread being disposed in a spiral around the central body and including a starting pitch at the distal end of the central body, wherein at least a portion of the thread is oriented longitudinally relative to the central axis of the suture anchor to facilitate insertion of the anchor.

Abstract
A suture anchor has a continuous thread spiralling around a tapering central core. At the distal end of the thread, the suture anchor has a starting pitch to facilitate insertion of the anchor into bone. The proximal end of the suture anchor receives at least one strand of suture. At the proximal end, the suture anchor has a large thread surface per turn of thread.

12. A method of anchoring suture in bone, the method comprising the steps:
-
providing a suture anchor comprising a central body having a central axis, a distal end and a proximal end, the central body being tapered along a major portion thereof from a maximum diameter near the proximal end to a minimum diameter toward the distal end; and
a continuous thread for anchoring the suture anchor in soft bone, the continuous thread being disposed in a spiral around the central body and including a starting pitch at the distal end of the central body, wherein at least a portion of the thread is oriented longitudinally relative to the central axis of the suture anchor to facilitate insertion of the anchor;
threading suture through the proximal end of the suture anchor; and
driving the suture anchor into the bone. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. An assembly of a driver and suture anchor for securing suture to soft bone, comprising:
-
a driver for driving a suture anchor into soft bone, the driver comprising a tubular shaft having a distal end and a proximal end, and a handle disposed on the proximal end of the tubular shaft; and
a suture anchor inserted into the distal end of the driver, the suture anchor comprising a central body having a central axis, a distal end and a proximal end, the central body being tapered along a major portion thereof from a maximum diameter near the proximal end to a minimum diameter toward the distal end;
a drive head disposed on the proximal end of the central body, the drive head being configured to receive at least one strand of flexible material; and
a continuous thread for anchoring the suture anchor in soft bone, the continuous thread being disposed in a spiral around the central body and including a starting pitch at the distal end of the central body, wherein at least a portion of the thread is oriented longitudinally relative to the central axis of the suture anchor to facilitate insertion of the anchor. - View Dependent Claims (22, 23)
