Publication number: 20220039944Abstract: Implants, implant systems, and methods for treatment of mitral valve regurgitation and other valve diseases generally include a coaptation assist body which remains within the blood flow path as the leaflets of the valve move, the valve bodies often being relatively thin, elongate (along the blood flow path), and/or conformable structures which extend laterally from commissure to commissure, allowing the native leaflets to engage and seal against the large, opposed surfaces on either side of the valve body during the heart cycle phase when the ventricle contracts to empty that chamber of blood, and allows blood to pass around the valve body so that blood flows from the atrium to the ventricle during the filling phase of the heart cycle. Separate deployment of independent anchors near each of the commissures may facilitate positioning and support of an exemplary triangular valve body, with a third anchor being deployed in the ventricle.Type: ApplicationFiled: September 21, 2021Publication date: February 10, 2022Inventors: Alex Khairkhahan, Michael D. Lesh

Publication number: 20220000601Abstract: Embodiments of the present disclosure include, for example, an embolic protection system (EPS) including an inner-body having a body diameter and a distal section, and an expandable filter arranged on or adjacent at least the distal section of the inner-body. The filter is configured to include a plurality of pores, sized to allow the flow of the blood with limited interruption and capture of emboli greater than the pore size. Such embodiments may also include an expandable introducer sheath/sleeve having a sheath diameter configured to accommodate the inner-body and filter, including the distal portion, when unexpanded, as well as a tear-away (TA) sleeve having a sleeve diameter configured to accommodate the introducer sheath containing the inner-body and filter when unexpanded.Type: ApplicationFiled: November 15, 2019Publication date: January 6, 2022Inventors: Sebastian KHAIRKHAHAN, Alex KHAIRKHAHAN

Patent number: 9597514Abstract: Embodiments of the present invention generally relate to epicardial heart rhythm management. In some embodiments a method is provided for managing heart rhythm by implanting a pa device within the pericardial space of a patient. In some embodiments, an implantable device is provided for pacing the epicardial surface of a patient. The device may include a first module coupled to a second module by a tether. The first and second modules may be selectively placed for bi-ventricular pacing or for dual chamber pacing in some embodiments. Optionally the modules may be separate and may wirelessly communicate with one another and may also communicate with a heart stimulation device programmer. Optionally, a plurality of devices may be implanted in the pericardial space. A delivery device for delivering the implantable device to the pericardial space is also provided. Further embodiments provide implant retrieval devices and methods.Type: GrantFiled: December 7, 2015Date of Patent: March 21, 2017Assignee: VQUAD MEDICALInventors: Alex Khairkhahan, Sebastian Khairkhahan
