Abstract: A medical probe device comprises a catheter having a stylet guide housing with one or more stylet ports in a side wall thereof and a stylet guide for directing a flexible stylet outward through the stylet port and through intervening tissue at a preselected, adjustable angle to a target tissue. The total catheter assembly includes a stylet guide lumen communicating with the stylet port and a stylet positioned in said stylet guide lumen for longitudinal movement from the port through intervening tissue to a target tissue. The stylet can be an electrical conductor enclosed within a non-conductive layer, the electrical conductor being a radiofrequency electrode. Preferably, the non-conductive layer is a sleeve which is axially moveable on the electrical conductor to expose a selected portion of the electrical conductor surface in the target tissue. The stylet can also be a microwave antenna. The stylet can also be a hollow tube for delivering treatment fluid to the target tissue. It can also include a fiber optic cable for laser treatment. The catheter can include one or more inflatable balloons located adjacent to the stylet port for anchoring the catheter or dilation. Ultrasound transponders and temperature sensors can be attached to the probe end and/or stylet. The stylet guide can define a stylet path from an axial orientation in the catheter through a curved portion to a lateral orientation at the stylet port.

Abstract: This invention provides a method and system for the curative treatment of obesity. A first aspect of this invention is that it enables identification of the nerves responsible for the relaxation of the stomach muscles that occurs prior to and during eating. A second aspect of the invention is that it allows the physician to identify focal nerve sites in the stomach and upper duodenum that are associated with producing sensations of hunger and satiety. Nervous transmission from these sites can be modulated or blocked all together so as to minimize the sensation of hunger. A third aspect of this invention is that allows a physician to shrink selected portions of the innermost oblique muscle and middle circular muscle layers of the stomach. This can be performed in a physician's office using local anesthesia. Shrinkage of these muscles produces a feeling of satiety that enhances the patient's efforts to restrict his caloric intake.
Abstract translation: 本发明提供了治疗肥胖症的方法和系统。 本发明的第一方面是能够识别在进食之前和期间发生的负责放松胃肌肉的神经。 本发明的第二方面是其允许医师识别与产生饥饿感和饱腹感相关的胃和上十二指肠中的局灶性神经部位。 这些地点的神经传播可以一起被调制或阻挡,以便最大限度地减少饥饿感。 本发明的第三方面是允许医师收缩胃的最内倾斜肌肉和中间圆形肌肉层的选定部分。 这可以在医生办公室使用局部麻醉进行。 这些肌肉的收缩会产生饱腹感,从而增强患者的限制热量摄取的努力。

Abstract: A device for introducing a catheter into a vessel through a puncture in a vessel and for sealing the puncture. The device includes an elongated body having a proximal end and a distal end sized to be positioned within a tissue site which includes the puncture. The elongated body includes a utility lumen sized to allow a catheter to be delivered through the utility lumen. The utility lumen is positioned within the elongated body so positioning the elongated body within the tissue site allows a catheter delivered through the utility lumen to enter the vessel. The elongated body also includes a closure lumen having an entrance port. A closure composition can be delivered through the entrance port into the closure lumen. The closure lumen also includes an exit port adjacent the distal end of the elongated body. The closure composition delivered into the closure lumen can be delivered through the exit port to the tissue site adjacent the puncture.

Abstract: An apparatus to treat a sphincter includes a catheter means including a catheter means distal portion means. An energy delivery device means is coupled to the catheter means and includes a tissue piercing distal end. The energy delivery device means is configured to pierce a sphincter exterior surface, advance a sufficient distance in an interior of the sphincter to a tissue site, deliver energy to the tissue site and create controlled cell necrosis of the sphincter in order to reduce a frequency of sphincter relaxation. A cable means is coupled to the energy delivery device means.

Abstract: An RF treatment apparatus includes a catheter with a catheter lumen. A removable needle electrode is positioned in the catheter lumen in a fixed relationship to the catheter. The needle catheter includes a needle lumen and a needle electrode distal end. A removable introducer is slidably positioned in the needle lumen. The introducer includes an introducer distal end. A first sensor is positioned on a surface of the needle electrode or the insulator. An RF power source is coupled to the needle electrode and a return electrode. An insulator sleeve is slidably positioned around the electrode and includes a second sensor. Resources are associated with the electrode, sensors as well as the RF power source for maintaining a selected power at the electrode independent of changes in current or voltage.

Abstract: A device and method are provided for sealing a puncture in a body vessel. The device has an elongated body having a proximal end and a distal end sized to be positioned within a lumen of the body vessel; at least one closure composition precursor lumen within the elongated body having a entrance port adjacent the proximal end of the elongated body through which one or more fluent closure composition precursors can be delivered into the closure composition precursor lumen and an exit port adjacent the distal end of the elongated body through which the one or more fluent closure composition precursors can be delivered outside the vessel adjacent the vessel puncture; and a microwave antenna for delivering microwave energy adjacent the distal end of the elongated body to the fluent closure compound precursor. The microwave antenna according to this embodiment is preferably incorporated onto the elongated body adjacent the body distal end. Alternatively, the device can include a guidewire lumen and a guidewire which includes a microwave antenna.
