EDGE TO EDGE REPAIR OF THE MITRAL VALVE
The present invention describes systems and methods for treating mitral valve regurgitation. The treatment includes a systems and method of modifying the mitral valve by attaching a device to each leaflet and pulling them toward each other to stop mitral valve regurgitation.
DISPOSABLE INSTRUMENT NOSEPIECES FOR REPAIRING SOFT TISSUE TO BONE COUPLING
In one embodiment, a suture anchor installation system for orthopedic surgery is disclosed including a reusable or disposable handle, and one or more reusable or disposable screw-on tool nosepieces for orthopedic surgery that are configured to be coupled to the handle. The one or more reusable or disposable screw-on tool nosepieces include an awl, a tap, a suture anchor install tool, and a suture anchor adjustment tool for orthopedic surgery. The nosepieces may alternatively press-on or snap-on with a barb/groove configuration or rectangular driver/ball/socket universal joint configuration with an engineering fit such as a running, sliding, or slip fit, a locational or transition fit, a force fit, a friction fit, or an interference fit.
SUTURE ANCHOR FOR KNOTLESS FIXATION OF TISSUE
A suture anchor for knotless fixation of tissue. The suture anchor includes an implant configured to hold a suture to be anchored in bone without requiring suture knots. The suture is secured in bone by inserting the implant holding the suture into a hole in the bone, and advancing a fixation device, such as a cannulated interference screw, over a shaft at the proximal end of the implant.
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.
Methods for anchoring suture to bone
Methods and devices are provided for anchoring suture to bone. In one exemplary embodiment, a cannulated suture anchor is provided and it includes a suture-engaging member formed therein and configured to receive a suture therearound such that trailing ends of the suture can extend through the suture anchor. The suture anchor can also include at least a proximal portion having dual threads to facilitate engagement with bone. The present invention also provides exemplary sutures and drivers that can be used with the various methods and devices disclosed herein, or with other methods and devices known in the art.
Methods of securing a cardiac implant using knotless suture clamps
Suture locking clamps for securing prostheses such as heart valves or annuloplasty rings with sutures and without using knots improve the ease of implantation. The clamps have opposed clamp halves separated by a slot opening to one side and surrounded by a biasing member such as one or more C-clip springs. Sutures pass laterally into the slot which is held open by a retention member positioned between the clamp halves. The locking clamp slides along the sutures into position, the tension of the sutures is adjusted, and the retention member removed to allow the biasing member to clamp the sutures between the clamp halves. A delivery tool used to deliver and deploy the locking clamps contains a number of clamps within a delivery tube in a stack and bonded together for safety and a common retention member. The tool has a longitudinal channel on one side for entry of sutures.
Soft anchor made from suture filament and suture tape
An anchor is provided for placement in or against tissue. The anchor includes a flat fibrous construct having a first end and a second end; and a filament having a first end and a second end passing through the fibrous construct in two locations including a first passing location nearest a first end of the fibrous construct, a second passing location nearest a second end of the fibrous construct, the filament remaining free to slide through the first passing location and the second passing location such that the filament can be removed from the flat fibrous construct from the first end of the fibrous construct and the second end of the fibrous construct. The anchor can be inserted into a bone hole and deployed.
Delivering a constricting cord to a cardiac valve annulus using balloon-assisted positioning
A constricting cord can be delivered to the vicinity of an annulus using an apparatus that includes a set of support arms, with a respective anchor launcher supported by each of the support arms. An inflatable first balloon is configured to push the support arms away from each other when the first balloon is inflated. An inflatable second balloon is mounted to a shaft and is configured for inflation when the second balloon is disposed distally beyond the first balloon. In some embodiments, the distal balloon is inflated while it is in a ventricle. In some embodiments, the distal balloon is inflated while it is in a pulmonary artery.
Surgical constructs for tissue fixation and methods of tissue repairs
Surgical constructs, assemblies and methods of tissue fixation are disclosed. A surgical construct includes a spreadable web attached to a plurality of peripheral strands. The spreadable web may be tensionable and may include one or more flexible filaments or strands. At least one of the filaments is coupled to the peripheral strands. The filaments may extend from the peripheral strands in different directions and/or orientations. The spreadable web is expandable and can be adjusted to various widths. The spreadable web may be knotless. The spreadable web may be tensionable. The surgical construct may be attached to one or more knotted or knotless fixation devices.
BONE ANCHOR
A bone anchor for coupling tissue to bone comprising an anchor body having a hollow interior, an open proximal end in fluid communication with the hollow interior, and a distal end; and a suture anchor extending from the anchor body and distal to the open proximal end.
