Patent number: 9757193Abstract: Methods and apparatus are provided for non-continuous circumferential treatment of a body lumen. Apparatus may be positioned within a body lumen of a patient and may deliver energy at a first lengthwise and angular position to create a less-than-full circumferential treatment zone at the first position. The apparatus also may deliver energy at one or more additional lengthwise and angular positions within the body lumen to create less-than-full circumferential treatment zone(s) at the one or more additional positions that are offset lengthwise and angularly from the first treatment zone.

Patent number: 9504607Abstract: A method and device to stabilize the cornea with fewer adverse effects. In particular, a greater stability and shorter treatment time are to be made possible. To this end, the cornea is locally irradiated successively at different sites so that collagen fibers are indirectly or directly crosslinked at the irradiated sites. In this way, the collagen fibers are advantageously crosslinked in a spatially resolved manner. Accordingly, the entire eye need not be irradiated with tissue-damaging UV light, and regions having a weaker structure can be locally stabilized selectively. The sites of the cornea are preferably irradiated so that the collagen fibers are ionized in each instance by photoabsorption of a plurality of photons which each have an energy below an ionizing energy of a given molecule. After a short treatment period, strong covalent bonds are formed directly between the collagen fibers. Crosslinking agents need not be used.Type: GrantFiled: May 5, 2011Date of Patent: November 29, 2016Assignee: Carl Zeiss Meditec AGInventor: Christoph Russmann

Patent number: 9474573Abstract: A device for treating spinal tissue of a patient's body may include an energy source and first and second probe assemblies. Each of the probe assemblies may have an electrically conductive energy delivery device electrically coupled to the energy source, and may also have an electrothermal device for cooling the probe assembly. The device is configured so that the energy source delivers energy to the spinal tissue through the energy delivery devices in a bipolar mode that concentrates delivered energy between the energy delivery devices to create a lesion within the spinal tissue while the electrothermal devices cool the probe assemblies. Related methods of use include cooling, at times via an electrothermal device.Type: GrantFiled: December 31, 2013Date of Patent: October 25, 2016Assignee: Avent, Inc.Inventors: Mark Leung, Krishan Shah, Laura Conquergood, Subashini Chandran, Neil Godara
