  • Patent number: 11253695
    Abstract: A handheld, therapeutic electrode and connector that are compatible with high voltages from a pulse generator are disclosed. The electrode includes therapeutic terminals on a tip configured to deliver high voltage pulses safely to a patient. The electrode includes sleeves, bosses, wiring channels, and other features that maximize a minimum clearance distance (across non-conductive surfaces) and air clearance between conductive connectors themselves or the connectors and a user, thus preventing dangerous arcing. Internal surfaces and seams are taken into account. The connector and its mating outlet can include similar features to maximize clearance distance. Skirts, skirt holes, and finger stops are also employed, and they can be on either the connector or outlet, or the tip or handle of the electrode.

  • Patent number: 11213343
    Abstract: An irrigated needle electrode ablation catheter has a distal tip section with a tip electrode, a needle electrode assembly longitudinal movable relative to the catheter, and a needle centering insert in a channel in the tip electrode. The assembly has a proximal tubing and a distal needle electrode, and the insert supports the needle electrode in the channel at a predetermined separation distance from the tip electrode while enabling irrigation to flow circumferentially around the needle electrode through the channel and exit at the distal end of the tip electrode. The catheter also provides a first dedicated fluid pathway through the assembly and exits at the distal end of the needle electrode, and a second dedicated fluid pathway to supply fluid to the channel in the tip electrode, wherein the second pathway is defined by a guide tube and directed by a plunger member.

  • Patent number: 11202672
    Abstract: A method for maintaining patency in a duct or hollow vessel located within the body of a patient is described wherein the duct includes one or more obstructions. The method comprises the steps of introducing a device into the duct, the device comprising a catheter having a distal and a proximal end, wherein the distal end includes a distal tip portion and wherein the distal tip portion comprises at least one energy delivery member; locating the device within the duct at a position proximal to the obstruction; delivering energy to the duct and any surrounding tissue via the at least one energy delivery member for a specified time period, so that the obstruction is removed from the duct; and withdrawing the device from the duct. It is optional to subsequently place a device such as a stent at the therapy site in order to further maintain long term patency of the duct. It is also optional to apply a dilation force to the duct or hollow vessel after the energy delivery phase.

  • Patent number: 10010454
    Abstract: Systems, methods, and devices are presented for treating a tissue site and managing hair proximate the tissue site. A composition is provided for inhibiting, removing, or weakening hair proximate the tissue site and for providing an improved fluid seal by a flexible film drape over the tissue site. In some example embodiments, a hair-modification agent is disposed at least proximate a peripheral edge of a treatment manifold between a drape and epidermis proximate a tissue site. The hair-modification agent can be configured to flow over imperfections on the epidermis and to form a fluid seal against the epidermis, and can further be configured to at least substantially weaken hair on the epidermis as the hair encounters the hair-modification agent.

  • Patent number: 10004610
    Abstract: Systems and methods for facilitating treatment are disclosed that can include the use of imaging techniques in conjunction with one or more non-invasive techniques for modifying tissue, e.g., tissue in or around the spine. Depending on the type of treatment to be performed, various imaging modalities may be suitable for visualizing the tissue. Energy can be applied to tissue from outside of the body such that the tissue is modified in a non-invasive manner. For example, focused ultrasound can be used to dissect body tissues or can be applied to specific regions of tissue to change a characteristic of the tissue, e.g., increase its elasticity. The methods disclosed herein can be stand-alone treatments or can be performed prior to one or more surgical procedures. For example, non-invasive imaging and modification of body tissues can facilitate accessing the spine, preparing an interbody space, and/or surgically correcting the spine.

  • Patent number: 9980738
    Abstract: A device for simultaneously monitoring the health of surgical drills and detecting proximity to critical structures during surgery is described herein. By using various sensors (e.g. microphones, accelerometers, temperature sensors, etc.), signals from the drill can be measured and analyzed. The processed signals can then be used to indicate the proximity of the drill bit to critical structures, such as the patient's brain, and identify drill health issues (e.g. worn bearings, misaligned rotational axis, etc.).

  • Patent number: 9872728
    Abstract: A catheter includes an inflation balloon and at least one electrode. The inflation balloon is inflatable within a vessel. The at least one electrode extends around at least a portion of a periphery of the inflation balloon. The at least one electrode is expandable as the inflation balloon is inflated, and contracts as the inflation balloon is deflated. The at least one electrode is held in place along a length of the inflation balloon with a tether member, which is secured at opposing distal and proximal ends of the inflation balloon.

  • Patent number: 9693763
    Abstract: A method of performing an operation, e.g. a spinal operation, on a patient using a retractor comprising a pair of blade assemblies which are adapted to open about a set of axes that are not parallel to a third spatial axis, and further comprising a pair of arms, which are adapted to move the pair of blade assemblies apart from one another in the third spatial axis. In the method, the blade assemblies are closed to assume a low profile, inserted into a relatively small incision, and stretched apart from each other, thereby stretching the skin about the incision to form an aperture longer than the incision. The blade assemblies are then opened by rotating the blades about the set of axes, stretching the skin around the incision in a second direction that is substantially perpendicular to the first direction (i.e. the direction of the incision).
