Abstract
An implantable prosthetic device has a coaption element, a pair of paddles, and at least one cover. The coaption element is configured to be positioned within the native heart valve orifice to help fill a space where the native valve is regurgitant and form a more effective seal. The cover can at least partially cover the coaption element and/or the pair of paddles. The cover is at least partially closed by alternating in and out stitches that are substantially unexposed when the cover is secured on the device.
Core Innovation
The invention relates to a valve repair device for repairing a native valve of a patient. The device includes a coaption element and a cover that at least partially surrounds the coaption element, and at least a portion of the cover is closed around the coaption element by alternating in and out stitches formed by a thread. The thread is pulled tight such that first and second sides are pulled inwardly toward a center of the cover, and the first surface at a first portion is directed toward a first surface at a second portion.
With the thread pulled tight, the alternating in and out stitches are disposed within the cover and unexposed. The cover is closed around the coaption element such that the cover portions pull inwardly and the stitches remain contained and unexposed within the closed cover.
In related embodiments, the device includes a pair of anchors movable between an open position and a closed position, and a cover that at least partially surrounds at least one anchor. In a further system embodiment, the invention is implemented with a catheter and a valve repair device having a pair of movable paddles connected to the coaption element, where the cover at least partially surrounds the coaption element and at least partially surrounds the paddles and is closed by the same alternating in-and-out stitch concept with unexposed stitches.
Claims Coverage
The independent claims are directed to three inventive features. Across these claims, the core inventive subject matter is the cover-closure mechanism using alternating in and out stitches and thread tensioning to dispose the stitches within the cover and keep them unexposed.
Valve repair device with a coaption element and cover closed by alternating in and out stitches pulled tight to keep stitches unexposed
A valve repair device for repairing a native valve comprising a coaption element and a cover that at least partially surrounds the coaption element, wherein at least a portion of the cover is closed around the coaption element by alternating in and out stitches formed by a thread, and wherein the thread is pulled tight such that first and second sides are pulled inwardly toward a center of the cover so that in and out stitches are disposed within the cover and the in and out stitches are unexposed with the cover closed around the coaption element.
Valve repair device with movable anchors enclosed by a cover closed by alternating in and out stitches pulled tight to keep stitches unexposed
A valve repair device for repairing a native valve comprising a pair of anchors movable between an open position and a closed position and a cover that at least partially surrounds at least one anchor, wherein at least a portion of the cover is closed around the at least one anchor by alternating in and out stitches formed by a thread, and wherein the thread is pulled tight such that first and second sides are pulled inwardly toward a center of the cover so that in and out stitches are disposed within the cover and the in and out stitches are unexposed and the cover is closed around the at least one anchor.
Valve repair system with catheter and paddles enclosed by a cover closed by alternating in and out stitches pulled tight to keep stitches unexposed
A valve repair system for repairing a native valve comprising a catheter and a valve repair device having a coaption element, a pair of paddles connected to the coaption element movable between an open position and a closed position, and a cover that at least partially surrounds the coaption element and at least partially surrounds the at least one of the pair of paddles, wherein at least a portion of the cover is closed around one or more of the coaption element and the at least one paddle by alternating in and out stitches formed by a thread, and wherein the thread is pulled tight such that first and second sides are pulled inwardly toward a center of the cover so that in and out stitches are disposed within the cover and the in and out stitches are unexposed and the cover is closed around the coaption element.
Across the independent claims, the invention centers on enclosing structural elements of a native valve repair with a cover that is closed by alternating in and out stitches formed by a thread, where the thread is pulled tight to pull cover sides inward so the alternating stitches are disposed within the cover and remain unexposed.
Stated Advantages
The in and out stitches are disposed within the cover.
The in and out stitches are unexposed.
