20120046657 | Stent Graft Fenestration - A method for creating a channel through a foreign material located in a body of a patient, the foreign material defining a material first surface and a substantially opposed material second surface, the channel extending through the foreign material between the material first and second surfaces, the method using an apparatus including an electrode, the method comprising: positioning the electrode substantially adjacent to the material first surface; energizing the electrode with a radiofrequency current; and using the electrode energized with the radiofrequency current to deliver energy into the foreign material to create the channel, wherein the foreign material is included in a stent graft. | 02-23-2012 |
20120232665 | Devices and Methods for Treating Tissue Defects - The present disclosure describes embodiments for treating a defect in a tissue, the tissue having internal and external surfaces. A device includes a first portion for positioning at one of the internal and external surfaces for applying a treatment force to the defect. In addition, the device has a second portion for applying a counter-force, where the second portion is operable to be positioned so that the counter-force is applied on the other of the internal and external surfaces, away from the defect so as to substantially avoid application of force at the defect. Furthermore, the device includes a coupling member for connecting the inner and outer portions. Methods of using the device are described, for example in an intervertebral disc having a herniation. | 09-13-2012 |

20140018915 | Valve Replacement Devices, Delivery Device for a Valve Replacement Device and Method of Production of a Valve Replacement Device - A device for heart valve replacement comprises a valve component having at least two valve leaflets preferably made of pericardium tissue. Each valve leaflet includes at least two tabs. The device further includes a stent component configured to be radially compressible into a compressed state and expandable into a functional state. The stent component comprises a first end, a second end and at least one intermediate section arranged between said first and said second end. The intermediate section has at least two commissural posts generally aligned parallel to an axis spanning from the first end to the second end. The commissural posts are formed in the shape of a wishbone. | 01-16-2014 |
20140100560 | Fenestration through foreign material - Described herein is a method for creating a channel through a foreign material located in a body of a patient. The foreign material defines a material first surface and a substantially opposed material second surface and the channel extends through the foreign material between the material first and second surfaces. The method uses an apparatus including an electrode, and includes the steps of: positioning the electrode substantially adjacent to the material first surface; energizing the electrode with a radiofrequency current; and using the electrode energized with the radiofrequency current to deliver energy into the foreign material to create the channel. In some embodiments, the patient's body includes a heart defining a septum, the septum defines an aperture extending there-through and the foreign material extends across the aperture to cover the aperture. | 04-10-2014 |
20140100561 | Fenestration through foreign material - Described herein is a method for creating a channel through a foreign material located in a septum of a heart at the site of a septal defect. The foreign material defines a material first surface and a substantially opposed material second surface, and the channel extends through the foreign material at least partially between the material first and second surfaces. The method uses an apparatus including an electrode and includes the steps of: positioning the electrode substantially adjacent to the material first surface; energizing the electrode with a radiofrequency current; and using the electrode energized with the radiofrequency current to deliver energy into the foreign material to create the channel. | 04-10-2014 |
20140120531 | Devices, Solutions and Methods for Sample Collection - The disclosure relates to devices, solutions and methods for collecting and processing samples of bodily fluids containing cells (as well as embodiments for the collection, and processing and/or analysis of other fluids including toxic and/or hazardous substances/fluids). In addition, the disclosure relates generally to function genomic studies and to the isolation and preservation of cells from saliva and other bodily fluids (e.g., urine), for cellular analysis. With respect to devices for collection of bodily fluids, some embodiments include two mating bodies, a cap and a tube (for example), where, in some embodiments, the cap includes a closed interior space for holding a sample preservative solution and mates with the tube to constitute the (closed) sample collection device. Upon mating, the preservation solution flows into the closed interior space to preserve cells in the bodily fluid. The tube is configured to receive a donor sample of bodily fluid (e.g., saliva, urine), which can then be subjected to processing to extract a plurality of cells. The plurality of cells can be further processed to isolate one and/or another cell type therefrom. The plurality of cells, as well as the isolated cell type(s), can be analyzed for functional genomic and epigenetic studies, as well as biomarker discovery. | 05-01-2014 |
20140200649 | Systems, Methods and Devices for Retrograde Pericardial Release of a Prosthetic Heart Valve - Embodiments of the present disclosure are directed to stents, valved-stents, and associated methods and systems for their delivery via minimally-invasive surgery. | 07-17-2014 |
20140350668 | Prosthesis Seals and Methods for Sealing an Expandable Prosthesis - Embodiments of the present disclosure are related to devices and techniques for para-valve sealing of an expandable stent-valve implanted using a catheter. In some embodiments, a stent-valve is provided which comprises a seal sleeve/cuff containing material that swells when contacted by blood. A piercing tool may be included and used to permit a user to puncture the sleeve/cuff prior to introduction into a patient's body. In some embodiments, the sleeve/cuff has an integral tubular structure configured to withstand balloon expansion of the stent-valve during or after implantation. | 11-27-2014 |
