    摘要: Implantable devices, instruments, kits and methods for treatment of obesity. One or more devices can be implanted adjacent to or in contact with the stomach to occupy a space to prevent the stomach from expanding into that space as food is taken into the stomach. Alternatively, one or more devices may be implanted and expanded to displace at least a portion of the wall of the stomach to decrease the internal volume of the stomach that is available to receive food. Devices may be anchored to one or more internal structures at one or more locations without piercing through the wall of the stomach. Devices can be implanted using minimally invasive methods, such as percutaneous or laparoscopic methods. Delivery instruments are also provided. An intra-gastric sizing device is provided to facilitate implantation of an extra-gastric device in some method embodiments.

    摘要: Various high-strength microwave antenna assemblies are described herein. The microwave antenna has a radiating portion connected by a feedline to a power generating source, e.g., a generator. The antenna is a dipole antenna with the distal end of the radiating portion being tapered and terminating at a tip to allow for direct insertion into tissue. Antenna rigidity comes from placing distal and proximal radiating portions in a pre-stressed state, assembling them via threaded or overlapping joints, or fixedly attaching an inner conductor to the distal portion. The inner conductor is affixed to the distal portion by, e.g., welding, brazing, soldering, or by adhesives. A junction member made from a hard dielectric material, e.g., ceramic, can be placed between the two portions and can have uniform or non-uniform shapes to accommodate varying antenna designs. Electrical chokes may also be used to contain returning currents to the distal end of the antenna.
