ADJUSTABLE ANNULOPLASTY RING
This abstract first appeared for US patent application 18965942 titled 'ADJUSTABLE ANNULOPLASTY RING
Original Abstract Submitted
An annuloplasty ring for repair of mitral valves whose shape can be altered directly or remotely to perform post-implant size and/or shape adjustments. One version of the annuloplasty ring has a size-adjustable remodeling inner core within an outer suture-permeable interface for attaching the ring to an annulus. The inner core has a size-adjustable segment formed by short spaced-apart tubular sections that can move toward and way from one another such as on rails. Alternatively, short sections separated by compressible connectors may be used. One or more tethers may be attached to one side of the size-adjustable segment and pulled from the other side to constrict the segment. Multiple tethers may be connect at different locations around the ring to provide some control over where the ring constricts. An adjustment handle with a flexible shaft may be operated from outside the body to adjust the ring post-implant.
