  • Patent number: 10363402
    Abstract: A balloon dilation catheter includes a substantially rigid inner guide member and a movable shaft coupled to a balloon that is slidably mounted on the substantially rigid inner guide member. To treat a sinus cavity of a subject using the balloon dilation the substantially rigid inner guide member is advanced into a drainage pathway of the sinus (e.g., frontal recess) of the subject via a nasal passageway. The shaft and balloon are advanced in a distal direction over the substantially rigid inner guide member to place the balloon in the drainage pathway. The balloon is inflated to expand or otherwise remodel the drainage pathway.

  • Patent number: 9867599
    Abstract: An interventional device, e.g. a Vacuum Assisted Biopsy (VAB) needle, incorporating optical fibers such that biological tissue in a volume at a side of the interventional device can be substantially completely optically probed by optical spectroscopy. In a VAB embodiment, a plurality of optical fiber pairs connected to respective optical ports, are placed at opposite positions along the suction cavity, and they are readout subsequently allowing to make a map of the tissue properties along the place where the tissue will be cut by the VAB needle. Based on decision software in an optical console, it can be determined whether the tissue present in the cutting cavity is completely normal tissue or not, prior to actually performing the biopsy on the tissue. In this way a well defined end point for VAB is created.

  • Patent number: 9782221
    Abstract: Deep Tissue Low Intensity Laser Therapy or Treatment (DT-LILT) as described here is a novel methodology through which selective destruction of nociceptive (pain) nerves can be brought upon by a medical laser delivery system using the phenomenon of absorption and cell resonance. Using this method nerve cells that transmit pain can be selectively destroyed leaving the surrounding tissues intact as no heat is generated. The delivery system incorporates a fine needle through which a 703 nm (range 690 to 710) pulsed wave low intensity laser is delivered deep into the body, directly to the area of pain causing selective destruction of pain nerves. Laser devices based on this methodology should be used only by the physician or equivalent professional community since diagnosing and defining the area of pain is critical to providing successful pain relief.

The threaded portion of a dilator engages the tissue between the insertion site and the target site, and may be rotated for advancing through the target tissue in a more controlled fashion. The direct visualization capability may be used to visualize the ligament as the threaded distal portion passes through the ligamentum flavum. The devices and methods described may be used in procedures, for example, where ligaments surrounding the epidural space need to be dilated in order to deliver one or more surgical instruments into the epidural space.

  • Patent number: 8905921
    Abstract: An optical coupler is disclosed with an attachment section for mounting at a distal end of an optical imaging device for visualizing a surface area covered with an opaque fluid and/or particulate matter. The coupler includes a visualization section at one end of the coupler that includes a proximal surface for engaging the distal end of the optical imaging device, an attachment section connected to and extending away from the visualization section, an outer surface spaced apart from the proximal surface, and may include a hollow instrument channel extending from the proximal surface toward the outer surface. This surface extends continuously from a first outer side boundary across to a second opposite outer side boundary of the visualization section. The visualization section can be formed from an elastic material capable of transmitting an optical image of the surface area. In one form, the material is a silicone gel or elastomer.
