Mitral or tricuspid repair systems with multi-directional anchors
Prosthetic ring valve assemblies are disclosed. A prosthetic valve ring assembly includes an outer tube and a plurality of anchors. The outer tube includes a plurality of windows. The plurality of anchors are positioned inside the outer tube and about a perimeter of the outer tube. The plurality of anchors are configured to be emitted from the plurality of windows in order to anchor the prosthetic valve ring assembly to annulus tissue of a patient.
1. A prosthetic valve ring assembly, comprising:
an outer tube comprising a plurality of windows;
a plurality of anchors positioned inside the outer tube and around a perimeter of the outer tube, wherein the plurality of anchors are configured to be emitted from the plurality of windows to anchor the prosthetic valve ring assembly to a patient's annulus tissue, and wherein a first portion of the plurality of anchors is configured to be emitted to an atrial side of the annulus tissue in an outward and upward direction relative to a plane of the outer tube, and a second portion of the plurality of anchors is configured to be emitted to a ventricular side of the annulus tissue in an outward and downward direction relative to the plane of the outer tube;
a closure device configured to lock a distal end and a proximal end of the prosthetic valve ring assembly; and
an unsnapping pin configured to unlock the closure device to separate the distal end and the proximal end of the prosthetic valve ring assembly, thereby providing for repositioning or retrieval of the prosthetic valve ring assembly from the patient through a catheter.
2. The prosthetic valve ring assembly of claim 1 , wherein the plurality of anchors are created using a laser cutting technique.
3. The prosthetic valve ring assembly of claim 2 , wherein the laser cutting technique comprises cutting according to a laser cut pattern to define a plurality of windows through which the plurality of anchors are configured to be emitted.
4. The prosthetic valve ring assembly of claim 1 , further comprising a post adjustment mechanism comprising a flexible connection configured to move an anterior portion of the prosthetic valve ring assembly relative to a posterior portion of the prosthetic valve ring assembly, thereby changing at least one of a size and a geometry of the prosthetic valve ring assembly.
5. The prosthetic valve ring assembly of claim 1 , further comprising one or more bumps positioned on a perimeter of the prosthetic valve ring assembly and configured to apply additional pressure to trigones of the patient's annulus tissue, thereby providing improved anchoring of the prosthetic valve ring assembly.
6. The prosthetic valve ring assembly of claim 1 , wherein the closure device is interfaced to the outer tube by suture pins which are configured to function as pulleys for sutures.
