  • Patent number: 8961510
    Abstract: The endoscopic nasal palatoplasty procedure provides a reduction in the posterior aspect of the soft palate and/or uvula, thereby increasing the area of the nasopharyngeal passage between the soft palate and/or uvula and the back of the nasopharynx. This increased nasopharyngeal area promotes nasal breathing, thereby reducing reliance upon oral breathing and corresponding sleep-disordered breathing syndrome and associated problems such as sleep apnea and snoring. The procedure is performed using a conventional surgical implement, such as a Coblator® or other electro cauterizing or laser cauterizing implement, to ablate and cauterize a series of lesions in the soft palate and/or uvula. The procedure is performed by inserting the surgical implement through one of the nasal passages to access the superior surface of the soft palate and/or uvula.

  • Patent number: 8870864
    Abstract: An electrosurgical apparatus includes two assemblies, one of which is the primary assembly intended for a first surgical procedure, such as cutting tissue, and a secondary assembly intended for a second type of electrosurgical procedure, such as tissue coagulation. The secondary assembly fits over the electrode tip of the primary assembly and makes electrical contact with the electrode tip of the primary assembly. This allows for single instrument surgery whereby the secondary (coagulation) assembly provides bleeding control after the primary assembly has cut tissue. This combination significantly reduces operating time. The secondary assembly has a snap fit over the primary assembly so that it may be readily attached and detached several times during any surgical procedure, as the surgeon alternates between cutting tissue and coagulating the resulting incisions using the apparatus.

  • Patent number: 8753340
    Abstract: A catheter structure is provided for use with an electroviscerogram (EVG) system. The catheter structure includes an elongated tube structure having distal and proximal ends. Three electrodes are associated with distal end of the tube structure and are constructed and arranged obtain signals relating to myoelectrical activity internally of an intra-abdominal organ to thereby locate targeted tissue that includes main pathways of electrical generation in the organ. Therapy delivery structure, associated with the distal end of the tube structure and separate from the electrodes, is constructed and arranged to provide therapy at the targeted tissue simultaneously as the electrodes obtain the signals at the targeted tissue so that effectiveness of the therapy can be monitored.

  • Patent number: 8740900
    Abstract: An embodiment of an open-irrigated catheter system comprises a tip section, a distal insert, and mapping electrodes. The tip section has an exterior wall that defines an open interior region within the tip section. The exterior wall includes mapping electrode openings and irrigation ports. The exterior wall is conductive for delivering radio frequency (RF) energy for an RF ablation procedure. The irrigation ports are in fluid communication with the open interior region to allow fluid to flow from the open interior region through the irrigation ports. The distal insert is positioned within the tip section to separate the open region into a distal fluid reservoir and a proximal fluid reservoir. The mapping electrodes are positioned in the mapping electrode openings in the tip section.

  • Patent number: 8734440
    Abstract: A catheter comprising a flexible tubing having a proximal end and a distal end. An electrode assembly is attached to the distal end of the flexible tubing. The electrode assembly includes an electrically conductive tip electrode and a coupler which is connected between the tip electrode and the distal end of the flexible tubing. The coupler and the tip electrode are coupled by an interlocking connection. A first magnet is at least partially housed in the coupler. A fluid lumen extends through the flexible tubing to the coupler. The fluid lumen extends completely through the first magnet and connects to at least one port formed in the electrode assembly. A second magnet is spaced from the electrode assembly along a longitudinal axis of the tubing. The first magnet and the second magnet are responsive to an external magnetic field to selectively position and guide the electrode assembly within a body of a patient.
