20140330211 | ENGAGEMENT AND DELIVERY CATHETER SYSTEMS - A system for engaging heart tissue includes an engagement catheter defining a first lumen therethrough and having a suction port at or near a distal end and a vacuum port at or near a proximal end, a delivery catheter defining a delivery catheter lumen therethrough and configured for slidable insertion into the first lumen of the engagement catheter, and an implantable device capable of insertion into the delivery catheter lumen such that at least part of the implantable device extends from a delivery catheter distal end upon implantation into a patient, where the suction port is operable to removably attach to a targeted tissue on an interior wall of a heart of the patient after the engagement catheter has been advanced through a blood vessel and into the heart, thereby forming a reversible seal with the targeted tissue when a vacuum source is operatively coupled to the vacuum port. | 11-06-2014 |
20150051443 | DEVICES, SYSTEMS, AND METHODS FOR DEFORMING A BODY CHANNEL - Devices, system and methods for deforming body channels are disclosed herein. At least some embodiments described may be used to deform a body channel so as to decrease or prevent the normal intrachannel flow of material within the body channel. Such deformation may be used to treat such maladies as Gastroesophageal Reflux Disease. | 02-19-2015 |
20150064140 | METHODS AND USES OF BIOLOGICAL TISSUES FOR VARIOUS STENT AND OTHER MEDICAL APPLICATIONS - Methods and uses of biological tissues for various stent and other medical applications. In an exemplary embodiment of a method of processing a tissue of the present disclosure, the method comprises the steps of acquiring a mammalian tissue comprising at least a portion of a pulmonary region tissue, selecting a sample of pulmonary region tissue from the at least a portion of a pulmonary region tissue, and fixing the sample of pulmonary region tissue using a fixative, resulting in a fixed sample. In at least one embodiment, the step of selecting a sample of pulmonary region tissue comprises selecting a sample of pulmonary ligament tissue from the mammalian tissue. | 03-05-2015 |
20150073533 | LINKED DEFLECTION DEVICES, SYSTEMS AND METHODS FOR THE PREVENTION OF STROKE - Devices, systems, and methods for the prevention of stroke. Devices and systems hereof comprise stents configured to fit within at least part of an artery extending from an aortic arch, and at least one component comprising parallel convex struts for diverting emboli from entering an artery when the component is positioned at or near its ostium. The stents and the deflection component(s) are coupled in a linked configuration. Additionally, a retrieval system is provided, the retrieval system comprising a sleeve catheter and a retrieval device slidably disposed therein. The distal end of the retrieval device comprises an attachment portion configured to engage a device positioned within an artery extending from the aortic arch. | 03-12-2015 |
20150080805 | DEVICES AND SYSTEMS FOR ACCESSING CARDIAC TISSUE - Devices, systems, and methods for accessing the internal and external tissues of the heart are disclosed. At least some of the embodiments disclosed herein provide access to the external surface of the heart through the pericardial space for localized delivery of substances to the heart tissue. In addition, various disclosed embodiments provide access to the internal surface of the heart for aspiration and delivery of substances to a targeted region without disturbing or interfering with nearby structures or surfaces. | 03-19-2015 |
20150080855 | SYSTEMS, DEVICES, AND METHODS FOR LOCALIZED DRUG DELIVERY - Devices, systems, and methods for localized drug delivery. In at least one embodiment of a method of localized drug delivery, the method comprises the steps of placing a resorbable device within a tube, introducing the tube within a mammalian body at or near a tissue and/or organ within the mammalian body, and anchoring the resorbable device to the tissue and/or organ. Devices and systems useful for performing such a method are also disclosed herein, wherein an exemplary device comprises at least one drug release portion having at least one drug to be released over time and a binder intermixed with the at least one drug, and at least one resorbable anchor portion coupled to the at least one drug release portion. | 03-19-2015 |
