An apparatus for extraction of osseous tissue is disclosed. The apparatus includes a fixed portion and a clamp oriented along a generally central area of the fixed portion. The apparatus includes a first bone cutting device and a second bone cutting device coupled to the fixed portion and oriented around the clamp. The first bone cutting device and the second bone cutting device are coupled to the fixed portion using respective joints that accommodate orientations of the first bone cutting device and the second bone cutting device relative to the fixed portion along different horizontal and vertical axes. The clamp is configured to engage a first bone portion during a surgical procedure. The first bone cutting device and the second bone cutting device are configured to remove a second bone portion.

Sinusitis and other disorders of the ear, nose and throat are diagnosed and/or treated using minimally invasive approaches with flexible or rigid instruments. Various methods and devices are used for remodeling or changing the shape, size or configuration of a sinus ostium or duct or other anatomical structure in the ear, nose or throat; implanting a device, cells or tissues; removing matter from the ear, nose or throat; delivering diagnostic or therapeutic substances or performing other diagnostic or therapeutic procedures. Introducing devices (e.g., guide catheters, tubes, guidewires, elongate probes, other elongate members) may be used to facilitate insertion of working devices (e.g. catheters e.g. balloon catheters, guidewires, tissue cutting or remodeling devices, devices for implanting elements like stents, electrosurgical devices, energy emitting devices, devices for delivering diagnostic or therapeutic agents, substance delivery implants, scopes etc.) into the paranasal sinuses or other structures in the ear, nose or throat. Specific devices (e.g., tubular guides, guidewires, balloon catheters, tubular sheaths) are provided as are methods for manufacturing and using such devices to treat disorders of the ear, nose or throat.

Arthroplasty components include an articular surface and a bone-facing surface. The bone-facing surface includes a concave arrangement of planar surfaces which converge as they approach a middle portion of the articular surface. Instruments and implantation methods are also disclosed.

The invention comprises a method for fixating bones in the foot by aligning the bones in their desired position, inserting a screw in the aligned bones, inserting at least one transverse element near the head or tip of the screw, and tightening the screw to compress the bones. The screw comprises a shaft having first and second ends with spirally wound screw threads beginning near the first end and extending along the shaft. Advantageously, the screw is cannulated and screw threads are formed on an interior surface of the cannulation. Illustratively, the transverse elements may be staples, open-ended washers, or open-ended nuts. Reduction instruments and drill guides used in the invention are also disclosed.

A lumbar facet cage or implant and a system and method for delivery of the implant to the lumbar spine to immobilize the spine and promote fusion are described. In one aspect, the system and method are indicated for the fixation of the spine as an aid to fusion through immobilization of the lumbar facet joint. In one aspect, a cage or implant sized for the lumbar facet joint space that fixates the superior articular and inferior articular facets of the treated facet joint is described. In one aspect, the cage or implant includes one or more stop features.

Embodiments of apparatuses and methods for microfracture (e.g., forming a plurality of microfractures in a bone to encourage cartilage regeneration).

A surgical instrument for use on a patient's bone is provided and according to one embodiment the surgical instrument comprises a support rod or bar, and a breaking tool that is provided at an extremity of the support rod or bar, which breaking tool comprises a nose and a knife or chisel, wherein between the nose and the knife or chisel a room is provided which is arranged to receive material that is to be removed from the bone, wherein the knife or chisel has at least two surfaces facing the nose, which surfaces merge into a joint crossing line substantially dividing the knife or chisel into two parts on opposite sides of the crossing line, so as to provide a splitting operability to the knife or chisel.

Arthroplasty components include an articular surface and a bone-facing surface. The bone-facing surface includes a concave arrangement of planar surfaces which converge as they approach a middle portion of the articular surface. Instruments and implantation methods are also disclosed.

A Computer Assisted and Robot-Guided Laser Osteotome (CARLO) medical device (1) for perforating hard tissue, having a photoablation laser source (31) mounted in a robotic arm (2), and optical system (37) for focusing a laser beam in a target plane of the ostetomy line featuring an autotracking navigation system (8).

Embodiments of apparatuses and examplary methods for microfracture (e.g. forming a plurality of microfractures in a bone to encourage cartilage regeneration).
