Publication number: 20240131227Abstract: A sealing member for an implantable prosthesis includes a substrate comprising a substrate material, and one or more hydrogel structures disposed on an outwardly facing surface of the substrate. The hydrogel is stimulus responsive, and undergoes a change in volume, stiffness, or both when exposed to the stimulus. The sealing member promotes endothelialization and/or reduces paravalvular leakage.Type: ApplicationFiled: December 15, 2023Publication date: April 25, 2024Inventors: Ekaterina Tkatchouk, Oleksandr Barannyk, Jeanette Jasmine Corona Kelly

Publication number: 20230158204Abstract: An anti-fouling implantable material and a method of making the anti-fouling implantable material are disclosed. The anti-fouling implantable material includes a polymeric reinforcement layer, an intermediate layer comprising a protective polymer membrane, and an outer layer comprising an ionic polymer. The anti-fouling implantable material may have chemical and/or physical properties compatible with body tissue properties. The anti-fouling implantable material may be used for implantable medical devices, such as prosthetic heart valves and vascular grafts, among others.Type: ApplicationFiled: January 20, 2023Publication date: May 25, 2023Inventors: Ekaterina Tkatchouk, Angela B.

Publication number: 20210031028Abstract: Disclosed herein is a screw-in lead implantable in the pericardium of a patient heart and a system for delivering such leads to an implantation location. The leads include a helical tip electrode and a curvate body including a defibrillator coil with improved contact between the defibrillator coil and the patient heart. The delivery system includes a delivery catheter and lead receiving sheath disposed within the catheter. A fixation tine is disposed on one of the delivery catheter and the lead receiving sheath such that the delivery system may be anchored into the pericardium during fixation of the screw-in lead. In certain implementations, an implantable sleeve receives the leads to bias the defibrillator coil against the patient heart.Type: ApplicationFiled: October 13, 2020Publication date: February 4, 2021Inventors: Gene A. Bornzin, Devan Hughes, Keith Victorine, Zoltan Somogyi, Matthew Nojoomi, Ekaterina Tkatchouk, Xiaoyi Min

Publication number: 20190338100Abstract: The present invention relates to a monolith for processing fluid samples, and methods of making and using the monolith. The monolith can contain certain monomers or combinations of monomers that can be polymerized to give a polymeric monolith that can efficiently self-wick fluid. The self-wicking polymeric monolith can be used as a convenient tool for point of care/on site diagnostics and analytics. The monolith is easily stored and transported, comparatively cost-efficient to make, permits good detection of analyte molecules and is readily functionalizable by impregnation of and/or covalently grafting additional chemical moieties to either the whole monolith or in zones.Type: ApplicationFiled: May 14, 2019Publication date: November 7, 2019Applicants: Monolythix, Inc., Alfred E.
