A virtual surgical cutting guide may have first and second slots defining first and second axes respectively. The virtual surgical cutting guide may be positioned away from a vertebral body such that the first and second axes intersect at a distal point located in an interior of the vertebral body. The virtual surgical cutting guide may include the virtual surgical cutting guide with first and second cutting instruments. A method of performing a pedicle subtraction osteotomy may include the steps of placing the virtual surgical cutting guide over the first and second cutting instruments.

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.

The fusion device for fusing a synovial joint of a human or animal patient, in particular a human facet joint, finger joint or toe joint, includes two pin-shaped anchorage portions and arranged therebetween a stabilization portion. The anchorage portions include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions have a greater thickness and a greater depth than the stabilization portion. Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face of the fusion device. Thereby the liquefiable material is liquefied where in contact with the bone tissue and penetrates into the bone tissue, where after re-solidification it constitutes a positive fit connection between the fusion device and the bone tissue.

A fixation device is disclosed including an elongate body extending from a distal end to a proximal end. The distal end defines a blind hole having a diameter and extending to a depth from a distal tip. The diameter of the blind hole is sufficient to receive a k-wire therein.

The invention comprises an elongated device adapted for insertion, including self-insertion, through the body, especially the skull. The device has at least one effector or sensor and is configured to permit implantation of multiple functional components through a single entry site into the skull by directing the components at different angles. The device may be used to provide electrical, magnetic, and other stimulation therapy to a patient's brain. The lengths of the effectors, sensors, and other components may completely traverse skull thickness (at a diagonal angle) to barely protrude through to the brain's cortex. The components may directly contact the brain's cortex, but from there their signals can be directed to targets deeper within the brain. Effector lengths are directly proportional to their battery size and ability to store charge. Therefore, longer angled electrode effectors not limited by skull thickness permit longer-lasting batteries which expand treatment options.

Devices and methods for use in a hip replacement surgical procedure. One aspect includes methods and devices for reaming selective regions of the femoral canal. This may include reaming distal and proximal sections of the femoral canal prior to reaming a middle region of the canal. Another aspect includes a dummy implant and methods of use. The dummy implant is inserted into the femoral canal and may be used for one or more of retraction of the femur, gauging a space with the acetabulum, and further revising the femoral cut. The aspects may be used together in a single surgical procedure or separately in different surgical procedures.

The shaft-type instrument (1) has a shaft part (2), fixedly connected at one end to a shaft grip (3), and a sliding part (4). The sliding part (4) is displaceably mounted relative to the shaft part (2) and is, at one end, in operative connection with a pretensioned handgrip (5) such that by actuating the handgrip (5), the sliding part (4) is displaceable counter to the pretension. A respective lever arm (7, 7′) is articulated at two spaced apart shaft articulation points (6, 6′) on the shaft part (2) or shaft grip (3). The handgrip (5) has a coupling section (8) which connects the lever arms (7, 7′) and coupling joints (9, 9′) to one another such that same can pivot in the same direction. The coupling joints are spaced apart and a grip section (10) extends transverse to the coupling section (8) and to the shaft part (2).

A treatment device includes: a probe including a treatment portion that performs treatment to a treatment target portion by transmission of ultrasonic vibration; a first sheath having a first edge and enclosing a periphery of the probe; a second sheath having a second edge and enclosing a periphery of the first sheath; a suction path including a suction opening between the first edge and the second edge and provided between the first sheath and the second sheath; and a connection part communicating with the suction path and connected to a suction source.

An apparatus for inserting implants in a bone comprising a frame having a cartridge receiving chamber and a barrel. A cartridge defining a plurality of chambers is positioned in the cartridge receiving chamber so the chambers are selectively alignable with a longitudinal passage of the barrel. At least one instrument is positioned in one of the chambers, and a plurality of implants is positioned in the other chambers. A drive assembly is engageable with the instrument and the implants. The drive assembly is slidably and rotatably disposed in the frame and is moveable between a retracted position, an engaging position wherein the distal end of the drive assembly is positioned to engage the selected one of the instrument and the implants, and an extended position wherein the drive assembly extends through the chamber to transport the selected one of the instrument or the implant from the chamber to the distal end of the barrel.
