Method and apparatus for mitral valve chord repair
Methods and devices for transvascular prosthetic chordae tendinae implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, the catheter can be anchored to a superior surface of a mitral valve leaflet and a leaflet anchor can be advanced into the mitral valve leaflet to secure the mitral valve leaflet to a leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.
Suture cinching device with cutter
Medical devices for cinch and cutting one or more suture, and methods for making and using such devices are disclosed. An example medical device may include a coupler, a sleeve releasably coupled to the coupler, a cutter slidably disposed within the sleeve, and a suture cinching member movable into and out of the sleeve. A wire may extend through and be longitudinally movable within the coupler to move the suture cinching member and cutter.
Suture clip deployment device
Disclosed herein are suture clip delivery devices that can be loaded with several flat, disk-shaped suture clips and can deploy the suture clips one after another onto respective sutures without reloading the device with additional suture clips. An exemplary device includes a handle portion with an actuation mechanism that is coupled to a shaft portion that holds and deploys the suture clips. The shaft portion includes a mandrel on which the suture clips are mounted and a retainer that restricts the suture clips from moving proximally when the actuation mechanism pulls the mandrel proximally, which causes a distal-most suture clip to slide off the mandrel and be deployed onto one or more suture. The mandrel and remaining suture clips can then move distally to prepare to deploy the next suture clip.
Leaflet capture and anchor deployment system
Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, a leaflet connector carried by a distal end of the catheter can be anchored to a superior surface of a mitral valve leaflet. A needle is axially advanceable through the leaflet connector and through the leaflet. A leaflet anchor having a leaflet suture can be advanced out of the needle to secure the mitral valve leaflet to the leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.
Median lobe destruction apparatus and method
A system and associated method for altering or destroying tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders. In one aspect, the system includes a device configured to deploy devices for altering the lobes of a prostate.
Heart valve repair method
The present disclosure provides a heart valve repair method, comprising: advancing a distal end of a suture implanting apparatus from an outside of a body through a transapical approach into a left ventricle or a right ventricle of a heart; holding each leaflet of a heart valve with the distal end of the suture implanting apparatus; implanting at least one suture into the leaflet; withdrawing the suture implanting apparatus from the body; advancing a distal end of a suture locking apparatus from the outside of a body through a transapical approach into the corresponding left ventricle or the corresponding right ventricle; using the suture locking apparatus to lock the plurality of sutures; and withdrawing the suture locking apparatus from the body. The heart valve repair method has a simple surgical procedure, a low degree of patient trauma, and a high success rate of surgery.
PERICARDIAL ANCHORING SYSTEM
Various aspects of the present disclosure are directed toward apparatuses, systems, and methods for cardiac device anchoring and more specifically to accessing and anchoring in the pericardial space.
SUTURE LOCKING DEVICE AND SUTURE LOCKING DEVICE IMPLANTING APPARATUS
Disclosed are a suture locking device and a suture locking device implanting apparatus. The suture locking device comprises a suture pressing housing, a squeezing part and a driving component, wherein a suture pressing cavity is provided inside the suture pressing housing, the squeezing part is arranged in the suture pressing cavity, a first suture routing hole and a second suture routing hole are provided in the housing wall of the suture pressing housing, the driving component is configured to squeeze the squeezing part, and therefore, a locking suture sequentially penetrating the second suture routing hole and the first suture routing hole is squeezed.
REPAIR ASSEMBLY AND REPAIR ASSEMBLY IMPLANTATION DEVICE
