Electrosurgical system and method

InactiveUS7001380B2Lower impedanceMinimizing char formationCannulasDiagnosticsBenign conditionEnlarged tonsils
A method is disclosed for treating benign conditions, such as enlarged tonsils and / or adenoids located in a patient's throat or nasopharynx, or soft tissue lesions located in a patient's oropharynx or larynx. According to the method, a space containing the patient's nasopharynx, oropharynx or pharynx and larynx is isolated from the patient's trachea and lungs using an inflatable cuff tracheostomy tube or nasotracheal tube inserted in the patient's trachea. The cuff is inflated to occlude the trachea. The patient is placed in a supine position, whereupon at least a portion of the space containing the nasopharynx and / or oropharynx and larynx is filled with saline. An endoscope is then inserted into the space to view the operative site in which the tonsils or tissue lesion are to be treated. An electrosurgical instrument having an active tissue treatment electrode and a return electrode connected to an electrosurgical generator is then inserted into the space, either along side the endoscope or through the endoscope's working channel. The generator is then operated to apply a radio frequency voltage between the active and return electrodes of the electrosurgical instrument, whereby a conduction path is formed between the active and return electrodes, at least partially through the saline, whereupon the active electrode is manipulated to debulk or otherwise treat the soft tissue lesion or enlarged tonsils and / or adenoids.

Method and apparatus for ventilation / oxygenation during guided insertion of an endotracheal tube

A method for endotracheal intubation allows resuscitation of the patient to continue during intubation. A curved guide having a mask and a ventilation port is inserted into the patient's mouth and upper airway. The patient is initially resuscitated by supplying a flow of air / oxygen through the mask and simultaneously applying cardiac chest compressions. An endotracheal tube is inserted over the distal end of a fiber optic probe. Resuscitation continues without interruption while the fiber optic probe and endotracheal tube are advanced along the guide into the patient's airway, thereby allowing the physician to carefully guide the fiber optic probe and endotracheal tube to a position past the larynx while resuscitation continues.

Video-assisted laryngeal mask airway devices

A laryngeal mask airway device is provided that incorporates a video sensor, such as a CCD, CMOS or NMOS imaging chip, arranged to provide an image of the laryngeal inlet or other airway structures. The video sensor is electrically coupled to a reusable processing unit that receives the signals generated by the video sensor and generates a digital image of the interior of the patient's airway, thereby enabling the clinician to have immediate optical confirmation of the position of the mask aperture relative to the laryngeal inlet from the moment of insertion of the device.

Instrument for direct laryngoscopy with a rigid blade and flexible fiberoptics

A laryngoscope and flexible viewing device having means to carry an endotracheal tube into a patient and method of using the device are provided. The device allows a single user to view the interior of a patient's anatomy and change the view to better determine the path for. The device can be used by a single individual to simultaneously open the pathway to a patient's trachea and then deliver an intubation device, such as an endotracheal tube, without the assistance of another person. The device provides several options for the practitioner to both visualize the patient's larynx and deliver an endotracheal tube into the trachea, especially in patients considered to have difficult anatomy to intubate. The viewing device in a preferred embodiment is a fiberoptic scope and the device includes a pivoting means to allow the viewing means to provide a more panoramic view of the patient's throat area.

Gastro-laryngeal mask

InactiveUSRE39938E1Maximally openTracheal tubesSurgeryLaryngismusSphincter
A gastro-laryngeal mask features softly compliant construction of the distal half of the mask, wherein the mask is of generally elliptical configuration, with an inflatable peripheral cuff to seal and support the mask around the laryngeal inlet. A back cushion is inflatable to engage the back wall of the pharynx and thus to forwardly load the peripheral-cuff seal to the laryngeal inlet. An evacuation tube for external removal of a possible gastric discharge completes an evacuation or discharge passage contained within the mask and opening through the distal end of the peripheral cuff. Special provision is made for assuring integrity of the discharge passage within the flexible distal half of the mask, i.e., assuring against collapse of the distal-end half of the softly compliant evacuation tube in the distal region of the mask, such that inflation of the mask does not compromise viability of the evacuation tube by compressing softly compliant material of the evacuation tube during periods of mask inflation. The special provision also favors such collapse of the mask when deflated as to provide a leading flexible edge for piloting a safe and correct advancing insertional advance of the deflated mask in the patient's throat, in avoidance of epiglottis interference and to the point of locating engagement in the upper sphincter of the oesophagus.

Nerve monitoring device

The present invention provides a nerve monitoring device. The device includes a cannula, a sensor for monitoring the nerve and an alignment device. The cannula can be any surgical cannula, and is preferably an endotracheal tube. The sensor can be an electrode or other sensor that is capable of sensing nerve activity. The alignment device is a device that ensures that after insertion of the nerve sensor into a patient, the sensors are aligned to properly monitor the target nerve or muscle. The internal alignment device may communicate externally to surgeon by using electromagnetic energy as either a transmittor or a receiver. The mismatch of triangular laryngeal anatomy to circular cannula anatomy can be compensated for by a) altering the geometry (external shape) of the cannula and b) using soft, felt-like expandable electrodes. Rotational error can be compensated for by using a multi-electrode array wherein the optimized recording montage can be simply selected on the external recording device.
