A forceps includes a housing defining a window and having an outer shaft extending therefrom. An end effector assembly disposed at a distal end of the outer shaft includes first and second jaw members including distal portions and proximal portions and movable between spaced-apart and approximated positions. An inner shaft is slidably disposed within the outer shaft such that, when the jaw members are disposed in the spaced-apart position, the inner shaft is disposed in a distal position. When the jaw members are moved to the approximated position, the proximal portions urge the inner shaft to a proximal position. An indicator member coupled to the inner shaft includes first and second indicators. The first indicator is visible through the window when the inner shaft is disposed in the distal position. The second indicator is visible through the window when the inner shaft is disposed in the proximal position.

A device is described for treating a nasal airway by modifying a property of a nasal tissue of or near a nasal valve of the airway, without using a surgical incision or an implant, to decrease airflow resistance or perceived airflow resistance in the nasal airway. Various embodiments include an elongate shaft, a bipolar radiofrequency delivery member extending from one end of the shaft, and a handle attached to the elongate shaft at an opposite end from the radiofrequency delivery member. The radiofrequency delivery member is sized to be inserted into a nose and configured to at least temporarily deform the nasal tissue and deliver radiofrequency energy. The radiofrequency delivery member includes two rows of protruding electrodes disposed on a tissue contact surface, and the device is configured to deliver radiofrequency energy from one row of electrodes to the other row of electrodes.

An improved method and device for accurate, efficient surgical procedures are disclosed. The disclosed system consists in simultaneously using an elongated member that conveys energy to a treatment site and imaging means to control position of the elongated member and monitor treatment progress in real-time. In a preferred embodiment, for BPH, a twister fiber with a fused cap is used and ultrasound image guidance is obtained using a rectal probe. The method consists in placing an ultrasound rectal probe, fixed by mechanical means, and an optical fiber inserted into urethra. Initial positioning of probe is done under endoscopic/ultrasound control. The twister fiber probe operates in contact-mode. Treatment is monitored, real-time, by the ultrasound device. Additional imaging technologies include Positron Emission Tomography (PET), Computed Tomography (CT) or Optical Coherence Tomography. Other applications include the removal of tumorous (hyperplasic) tissue. Sources include lasers, higher power LEDs or bright lamps and photodynamic therapy.

Apparatus and methods for determining positioning of a energy delivery element include deploying a energy delivery element at a treatment site proximal to a vessel wall; using a multi-region pressure sensing apparatus to sense pressures applied in a plurality of directions about the energy delivery element; and determining an orientation of the energy delivery element based on the pressures measured in the plurality of directions about the energy delivery element.

A surgical device integrating a suction mechanism with a coagulation mechanism is provided for improving lesion creation capabilities. The device comprises an elongate member having an insulative covering attached about means for coagulating soft tissue. Openings through the covering expose regions of the coagulation-causing elements and are coupled to lumens in the elongate member which are routed to a vacuum source. A fluid source to passively transport fluid along the contacted soft tissue surface may be provided in order to push the maximum temperature deeper into tissue.

System and methods for channeling a path into bone include a trocar having a proximal end, distal end and a central channel disposed along a central axis of the trocar. The trocar includes a distal opening at or near the distal end of the trocar. The system includes a curved cannula sized to be received in the central channel, and having a curved distal end configured to be extended laterally outward from the distal opening in a curved path extending away from the trocar. The curved cannula has a central passageway having a diameter configured allow a probe to be delivered through the central passageway to a location beyond the curved path.

The present invention is concerned with a hair removal device for removal of red hairs that has a light emission unit having a substrate and a plurality of first LED dies emitting at a peak emission wavelength in a wavelength range of between about 480 nm and about 510 nm, the first LED dies being mounted on the substrate on an area in the range of between about 0.2 cm.sup.2 and about 100 cm.sup.2, wherein the hair removal device is arranged to emit a treatment light pulse by the first LED dies having a pulse length in the range of between about 30 ms and about 200 ms, and the first LED dies have a radiant flux such that a radiant fluence on the skin of a user in the range of between about 3 J/cm.sup.2 and about 6 J/cm.sup.2 is achieved by application of the treatment light pulse.

Disclosed is a system and method for treatment of skin disorders. More particularly, the disclosed invention is directed toward the use of multiple light sources for treating skin with or without the use of a topical compositions or photomodulation enhancing agents. Dual light emitting diodes may, for example, be used at relatively low power (less than about 10 J/cm2) to photomodulate skin or living tissue to reduce wrinkles, fine lines, acne, acne bacteria, and other skin disorders.

The present invention relates in part to nucleic acids, including nucleic acids encoding proteins, therapeutics and cosmetics comprising nucleic acids, methods for delivering nucleic acids to cells, tissues, organs, and patients, methods for inducing cells to express proteins using nucleic acids, methods, kits and devices for transfecting, gene editing, and reprogramming cells, and cells, organisms, therapeutics, and cosmetics produced using these methods, kits, and devices. Methods and products for altering the DNA sequence of a cell are described, as are methods and products for inducing cells to express proteins using synthetic RNA molecules, including cells present in vivo. Therapeutics comprising nucleic acids encoding gene-editing proteins are also described.

Medical methods and systems are provided for effecting lung volume reduction by selectively ablating segments of lung tissue.
