  • Patent number: 10959778
    Abstract: This invention relates to enhancement of the delivery of laser beams to internal surgical sites by employing, where practical, heavy water rather than normal water as both the irrigation fluid and the laser beam transmission medium that fills some or all of the space between the distal tip of the optical fiber to the surgical site. The use of heavy water is advantageous for surgical procedures employing lasers operating in the wavelength range of 1.0 microns to 2.5 microns where heavy water is substantially more transparent than normal water. This range includes the commercially important semiconductor diode laser operating at 1.47 microns where the optical attenuation coefficient in heavy water is less than one hundredth of that in normal water. Due to the rather high cost of heavy water, methods are described for collecting and re-cycling heavy water used during laser surgery to mitigate this cost.

  • Patent number: 10939959
    Abstract: A device, system, and method for optically evaluating and treating or ablating tissue. Specifically, device, system, and method allow for the optical and/or electrical evaluation of tissue at the same location(s) at which ablation or treatment or ablation energy is delivered. This allows for a more accurate evaluation of lesion formation and tissue condition before, during, and/or after a treatment or ablation procedure. In one embodiment, a device for performing a medical procedure includes an elongate body including a proximal portion, a distal portion having a distal end, and a longitudinal axis, and a distal tip electrode at the elongate body distal end, the tip electrode being optically transparent and electrically conductive. The device may also include optical windows in the elongate body aligned with one or more transparent lateral electrodes for optically interrogating tissue and/or for delivering treatment or ablation energy to tissue.

The fiber is manually withdrawn and during this time the radiation is administered in a manner appropriate for the vein being treating in regards to power or energy level. To maintain a constant proper energy density, the speed of withdrawal is measured and sent to a controlling mechanism. The controlling mechanism modifies the power emitted, pulse length or pulse rate to ensure that the vein or tissue receives a consistent dose of energy during manual withdrawal.

  • Patent number: 8961425
    Abstract: An intravascular ultrasound probe is disclosed, incorporating features for utilizing an advanced transducer technology on a rotating transducer shaft. In particular, the probe accommodates the transmission of the multitude of signals across the boundary between the rotary and stationary components of the probe required to support an advanced transducer technology. These advanced transducer technologies offer the potential for increased bandwidth, improved beam profiles, better signal to noise ratio, reduced manufacturing costs, advanced tissue characterization algorithms, and other desirable features. Furthermore, the inclusion of electronic components on the spinning side of the probe can be highly advantageous in terms of preserving maximum signal to noise ratio and signal fidelity, along with other performance benefits.

  • Patent number: 8951296
    Abstract: Devices and methods for therapeutic photodynamic modulation of neural function in a human. One embodiment of a method in accordance with the technology includes administering a photosensitizer to a human, wherein the photosensitizer preferentially accumulates at nerves proximate a blood vessel compared to non-neural tissue of the blood vessel. The method can further include irradiating the photosensitizer using a radiation emitter positioned within the human, wherein the radiation has a wavelength that causes the photosensitizer to react and alter at least a portion of the nerves thereby providing a therapeutic reduction in sympathetic neural activity. Several embodiments of the technology are useful for disrupting renal nerves, such as renal denervation, for treating hypertension, diabetes, congestive heart failure, and other indications.

  • Publication number: 20150005694
    Abstract: Apparatus and method for ablating target tissue including a non-linear area of tissue in the left atrium of a patient. The method can include selecting an ablation apparatus having an ablator with a tissue engagement section, penetrating a chest cavity of the patient, and identifying the target tissue. The method can also include positioning the ablation apparatus adjacent to the target tissue so that the tissue engagement section can transfer ablation energy to the target tissue. The method can further include energizing the tissue engagement section with ablation energy in order to create a footprint on the non-linear area of tissue in the left atrium and to reduce an overall mass of excitable tissue in the left atrium.

  • Patent number: 8920816
    Abstract: A method is provided for treating a neuromuscular defect in a subject. One step of the method includes locating a target nerve. After locating the target nerve, a treatment probe is provided. The treatment probe includes an elongated body member having a proximal end portion and a distal end portion. The distal end portion includes an energy delivery mechanism for stimulating or ablating the target nerve, a monitoring mechanism, and a fluid aspiration/delivery mechanism. Next, the target nerve is verified as an appropriate target for ablation by stimulating and then monitoring the target nerve via the energy delivery mechanism and the monitoring mechanism, respectively. After verifying the target nerve, a tumescent fluid is injected into the tissue surrounding the target nerve. An electric current is then delivered to the energy delivery mechanism to substantially ablate the target nerve.
