Publication number: 20190290357Abstract: In various embodiments, a catheter comprising an expandable electrode assembly or basket is provided. In specific embodiments, the basket is particularly useful for mapping electrical activity at one or more locations within the heart. The basket can comprise a plurality of bendable or deflectable arms. At least one of the arms may have varied flexibility over its length in the form of one or more discontinuities of stiffness or flexibility at an elbow region or other variances in flexibility over the arm's length. Such variance in flexibility may allow the arm to assume a different bent configuration or respond to external factors more positively than possible with an arm having a static or near static flexibility or stiffness over its length.Type: ApplicationFiled: March 29, 2019Publication date: September 26, 2019Inventors: Sacha C. Hall, Dale E. Just, Alan de la Rama, Cary Hata

Publication number: 20190290358Abstract: A method for tissue assessment includes ablating tissue at a site within a body of a living subject using an invasive probe applied to the site. At a first stage in ablation of the tissue, first measurements are made of scattered light intensities from the site at a plurality of different wavelengths. At a second stage in the ablation of the tissue, subsequent to the first stage, second measurements are made of the scattered light intensities from the site at the plurality of different wavelengths. Progress of the ablation is assessed by computing different, respective measures of change in the scattered light intensities at the different wavelengths occurring between the first and second measurements, and comparing the respective measures.Type: ApplicationFiled: June 10, 2019Publication date: September 26, 2019Inventors: Assaf GOVARI, Christopher Thomas BEECKLER, Joseph Thomas KEYES, Vadim GLINER

Publication number: 20190290360Abstract: Various methods, systems, and devices for treating tissue ablation are disclosed. Some embodiments disclosed herein pertain to methods of treating tumors, systems used for irradiating tissue and tumors with electromagnetic radiation, components and devices of that system, and kits for providing systems used for irradiating tissue and tumors with electromagnetic radiation. In some embodiments, the system provides sub-ablative infrared radiation that is absorbed by nanoparticles. In some embodiments, the nanoparticles absorb the radiation converting it into heat energy. In some embodiments, though the infrared radiation itself may be sub-ablative, the heat energy generated by the nanoparticles is sufficient to cause thermal coagulation, hyperthermia, and/or tissue ablation.Type: ApplicationFiled: December 14, 2017Publication date: September 26, 2019Inventors: Glenn Patrick Goodrich, Jon Alexander Schwartz, Andrew Mark Murphy

Publication number: 20190290361Abstract: A method of creating an augmented implant for a subject's bone or joint is provided. A virtual bone or joint model of the subject's bone or joint is obtained, the bone or joint model inclusive of bone property data for the subject's bone or joint including at least topology, density, and microarchitecture data. At least one of a size, a type, a geometry and a position for a virtual implant model is determined with respect to the bone or joint model to replace the region for removal using a processor. A stability region in the bone or joint surrounding the position of the implant model is located based on the bone or joint property data. The implant model is augmented with one or more stability features to interact with the stability region to improve implant stability using said processor or another processor. The augmented implant is so created.Type: ApplicationFiled: May 8, 2017Publication date: September 26, 2019Inventors: Stan G. SHALAYEV, In K. MUN, Micah FORSTEIN, Kyle KUZNIK, Timothy PACK
