A head for a ball striking device includes a bracing member connected to an upper sole surface located on the sole of the body opposite the bottom sole surface. The bracing member includes a first end connected to a first point on the upper sole surface, a second end connected to a second point on the upper sole surface spaced from the first point, and a bridge portion extending between the first and second ends. The bridge portion extends upward from the upper sole surface and is spaced from the upper sole surface. The bridge portion may be formed by one or more trusses, and may define a generally triangular shape in one embodiment. The first and second ends may be connected to the upper sole surface using a variety of techniques, e.g., welding or other integral joining technique, integral forming, adhesive or other bonding material, or other technique.

A golf club head including a club face defined by a toe end, a heel end, a top rail and a sole. The golf club head including a plurality of grooves disposed on the club face between the top rail and the sole. Each groove extends between the toe end and the heel end. Depths of the grooves vary in a direction extending between the top rail and the sole and in a direction extending between the heel end and the toe end. Widths of each of the plurality of grooves vary in a direction extending between the heel end and the toe end.

A tool for removing a coating from an end of a coated conduit comprising a metallic conduit having an outer diameter and a polymeric material applied over the outer diameter thereof is provided. The tool comprises: a guide member having an outer diameter sized to fit within an internal diameter of the metallic conduit; and a cylindrical cutting member having a substantially closed first end rotatably connected to an arbor, a substantially open second end, and a plurality of teeth elements. The cylindrical cutting member has an inner diameter that is substantially equal to the outer diameter of the metallic conduit such that when the cylindrical cutting member is rotated, the teeth elements remove the polymeric material from the outer diameter of the metallic conduit.

An aspiration system includes a pump and a control system in communication with the pump. The control system includes a microcontroller, an antenna configured to receive a signal, and a pump control board in communication with the microcontroller. The antenna is in communication with the microcontroller. Upon receiving the signal, the pump control board operates the pump to create negative pressure according to the signal.

An interbody spinal implant including a body having a top surface, a bottom surface, opposing lateral sides, and opposing anterior and posterior portions. At least a portion of the top surface, the bottom surface, or both surfaces has a roughened surface topography including both micro features and nano features, without sharp teeth that risk damage to bone structures, adapted to grip bone through friction generated when the implant is placed between two vertebrae and to inhibit migration of the implant. The roughened surface topography typically further includes macro features and the macro features, micro features, and nano features overlap. Also disclosed are methods of using such implants and processes of fabricating a roughened surface topography on a surface of an implant. The process includes separate and sequential macro processing, micro processing, and nano processing steps.

An outer member and an inner member constituting a wheel bearing device are assembled and the brake rotor is fixed to the hub ring of the inner member. In this state, the pad slide surfaces of the brake rotor are lathed with the reference provided by a wheel pilot end surface. Alternatively, the wheel pilot end surface of the hub ring by chucking the knuckle pilot of the outer member with the wheel bearing device put in its assembled state, and the pad slide surfaces of the brake rotor are lathed with the reference provided by the wheel pilot end surface.

Vascular treatment and methods include a plurality of self-expanding bulbs and a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Joints between woven structures and hypotubes include solder. Woven structures include patterns of radiopaque filaments measureable under x-ray. Structures are heat treated to include at least shapes at different temperatures. A catheter includes a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Heat treating systems include a detachable flange. Laser cutting systems include a fluid flow system.

Graft materials and devices for surgical breast procedures, as well as methods of making graft devices, are described.

There is provided a device for supporting an object during machining thereof, the object having a first object surface having a patient-specific configuration and a second object surface opposite the first object surface. The device comprises a support member adapted to support the object, the support member having a support surface shaped using patient-specific modeling and configured to matingly engage at least a portion of the first object surface for exposing the second object surface for machining thereof.
