Ablation probe tips (108, 148, 320, 360) and physical and virtual stents (110) for use in tooth bud ablation procedures that result in tooth agenesis as well as tooth bud ablation methods are described herein.

Methods and devices that displace bone or other hard tissue to create a cavity in the tissue. Where such methods and devices rely on a driving mechanism for providing moving of the device to form a profile that improves displacement of the tissue. These methods and devices also allow for creating a path or cavity in bone for insertion of bone cement or other filler to treat a fracture or other condition in the bone. The features relating to the methods and devices described herein can be applied in any region of bone or hard tissue where the tissue or bone is displaced to define a bore or cavity instead of being extracted from the body such as during a drilling or ablation procedure.

The present invention is about a device with a receiving antenna (110), wherein the receiving antenna (110) comprises a secondary coil (112), and being arranged for inductively connecting to a transmitting antenna (200) comprising a primary coil (202). The device of the invention is characterized in that the receiving antenna (110) further comprises a tertiary coil (114) arranged to have connection to a load in the device; and a capacitor (142) to which the secondary coil (112) is connected; and there is an encapsulation (120) comprising a low liquid permeability and non-conductive material encapsulating at least a part of the receiving antenna (110). Additionally, the present invention is about a power transfer system.

A method treating a root canal in a tooth by introducing into the pulp chamber of a tooth and pulsing a laser light into the fluid reservoir so as to disintegrate pulp within the root canal without generation of any significant heat in said liquid fluid so as to avoid elevating the temperature of any of the dentin, tooth, or other adjacent tissue more than about 5° C.

A method and system of treating connective tissue to increase flexibility of the connective tissue or decrease tension in the connective tissue includes forming perforations in the connective tissue to at least 90% of the depth or thickness of the connective tissue and maintaining the perforations in the connective tissue. The method alters the tissue to enhance the fundamental mechanisms involved the immunology, biochemistry, and molecular genetics of the metabolism of the connective tissue.

A handpiece for a surgical instrument having a valve position sensing circuit arranged to detect the position of a valve arranged to control the flow of fluid through the suction lumen of the instrument. The distal end of the handpiece is arranged to couple to a cutting accessory. The handpiece comprises: a housing; a suction lumen within the housing extending from the distal end of the handpiece to a proximal end of the handpiece; a valve arranged to control the flow of fluid through the suction lumen; and a valve position sensing circuit arranged to detect a position of the valve. The valve position sensing circuit can be used to alert a surgeon if the valve is closed when it would be preferable for it to be open. For example, if the motor is overheating, the in-joint temperature is too high, or the RF component is activated.

A surgical instrument includes a body extending along a longitudinal axis between opposite proximal and distal end surfaces. The distal end surface includes a first cavity and a second cavity. The first cavity includes a first light bulb disposed therein. The second cavity includes a second light bulb disposed therein. A shaft includes opposite proximal and distal ends. The proximal end is coupled to the body. A blade is coupled to the distal end. The first light bulb is an ultraviolet (UV) light bulb and the second light bulb is configured to emit visible light. Systems and methods of use are disclosed.

A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A cutting member having sharp edges formed from a wear-resistant ceramic material is carried at the distal end of the elongated sleeve. A motor drive is coupled to the proximal end of the elongated sleeve to rotate the sleeve at cutting member at high speed to cut bone and other hard tissue. An electrode is carried in a surface portion of ceramic cutting member for cautery or radiofrequency ablation of tissue when the sleeve and cutting member are is a stationary position.

A bipolar tunneling tool is configured to separate tissue adhesions and tunnel. The bipolar tunneling tool includes a handle, a tunneling shaft, a return electrode, an optical window, an active electrode, and an insulative housing. The tunneling shaft extends from the handle. The return electrode is disposed proximate a distal end of the tunneling shaft. The optical window is disposed proximate the distal end of the tunneling shaft, the optical window defining a channel. The active electrode is at least partially disposed within the channel. The active electrode is configured to dissect a tissue and cauterize the tissue. The insulative housing is configured to electrically insulate the active electrode from the return electrode.

Methods of using hardware (e.g., bone screws, anchors or other devices) previously inserted within the body to facilitate energy delivery are disclosed. The energy delivery (e.g., thermal energy) may be used for neuromodulation (such as stimulation or denervation), tissue heating and ablation, curing, and other applications in the spine and non-spine orthopedic locations.
