Embodiment Construction

[0095] It should be appreciated that like reference numbers are used to refer to substantially like structures or features in each drawing. Differences between such elements will generally be described, if necessary, but the same structure will not necessarily be described repeatedly for each figure, as reference may be made to the previous description for purposes of clarity and conciseness. Figure 1 schematically illustrates a typical replacement heart valve or prosthesis 10 that may be implanted in the place of a native heart valve, such as the mitral valve 12, using a catheter (not shown). The condition of the seal around the valve 10 (i.e., between the periphery of the replacement valve 10 and the native biological tissue) is desired to prevent blood flow when the leaflets 14, 16 of the replacement valve 10 open and close during the systolic and diastolic phases of the heart. Leakage around the perimeter of the replacement valve 10 . The portion of replacement heart valv...

Abstract

Systems and methods for parking a heart valve prosthesis. A system includes a helical anchor (30) formed as a plurality of coils (32) adapted to support a heart valve prosthesis (10), the plurality of coils (32) There is a coil portion (32) positioned above and below the heart valve annulus (12). A seal (50) is coupled to the helical anchor (30) and includes a portion extending between adjacent coils (32) for preventing blood from leaking through the helical anchor (30) and past the heart valve prosthesis body (10). The expandable helical anchor (30) is formed as a plurality of coils (32) adapted to support a heart valve prosthesis (10). At least one of the coils (32) is normally at a first diameter and is expandable to a second, larger diameter upon application of a radially outward force from within the helical anchor (30).

[0001] Cross References to Related Applications [0002] This application claims priority to the following U.S. Provisional Applications: U.S. Provisional Application Serial No. 61 / 864,860 (pending), filed August 12, 2013; U.S. Provisional Application Serial No. 61 / 867,287 (pending); and U.S. Provisional Application Serial No. 61 / 878,280 (pending), filed September 16, 2013, the disclosures of which are hereby incorporated by reference. technical field [0003] The present invention generally relates to medical approaches and devices related to heart valves, such as replacement techniques and devices. More specifically, the present invention relates to the replacement of heart valves with various malformations and dysfunctions. Background technique [0004] Complications of the mitral valve, which controls the flow of blood from the left atrium of the human heart to the left ventricle, are known to lead to fatal heart failure. One of the most common forms of valvular heart...
