Percutaneous arterial to venous anastomosis clip application catheter system and methods
A method of creating an anastomosis includes steps of advancing a distal tip of a catheter device through a first blood vessel into a second blood vessel, while simultaneously advancing a proximal base of the device into the first vessel, contacting a wall of the first vessel with a distal blunt surface on the proximal base. A further step is to retract the distal tip so that a proximal blunt base of the distal tip contacts a wall of the second vessel, thereby capturing the two vessel walls between the blunt surfaces of the proximal base and the distal tip. A controlled pressure is applied between the two blunt surfaces to compress and stabilize the captured tissue and approximate the vessel walls. A clip is deployed through the captured tissue to hold the tissue in place during the anastomosis procedure. The anastomosis is created by applying cutting energy to the captured tissue.
MAGNARETRACTOR SYSTEM AND METHOD
A system and method for performing surgical procedures within a body cavity, e.g. abdomen, uses a magnetized device is utilized to allow a surgeon to control intra-abdominal organs and objects. The system and method allows a surgeon to perform an intra-abdominal procedure without the need to position surgical tools inside of the body cavity. Additional surgical ports are not necessary as the magnetized device allows the surgeon to retract or position various objects within the abdomen.
SYSTEMS FOR PLACING A COAPTING MEMBER BETWEEN VALVULAR LEAFLETS
A system for reducing regurgitation includes a catheter and a coaptation member disposed along a distal end portion of the catheter, wherein the coaption member is sized to be advanced through a patient’s vasculature in a compressed configuration and wherein the coaptation member is expandable for deployment between leaflets of a native tricuspid valve. The coaptation member includes a frame covered with one or more panels of bioprosthetic tissue or flexible polymer to form a three-sided shape having three convex sides separated by rounded corners. An anchor is coupled to a proximal end portion of the catheter and is shaped for attachment to a vessel wall. After deployment, the anchor secures the position of the coaptation member relative to the native tricuspid valve.
REMOTE SURGICAL SUTURE SYSTEM
Systems, devices and methods described herein relate to endovascular devices for delivering sutures for securing grafts or other objects to patient vessels. In some embodiments, a suture includes a set of two legs having proximal ends joined to each other and elongate bodies that extend parallel to one another such that the set of two legs form a U-shaped structure. A suture delivery system can include a housing configured to contain a suture in a flattened configuration, and a deployment element having a ribbon-shaped distal portion disposed in the housing and including a set of formations, where the housing and the set of formations of the deployment element are configured to collectively constrain the suture in the flattened configuration until the suture is released through the opening of the housing.
DEVICE, SYSTEM, AND METHOD FOR TRANSCATHETER TREATMENT OF VALVULAR REGURGITATION
The invention relates to a device for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the valve; a system including the coaptation assistance element and anchors for implantation; a system including the coaptation assistance element and delivery catheter; and a method for transcatheter implantation of a coaptation element across a heart valve.
SYSTEMS AND METHODS FOR HEART VALVE LEAFLET REPAIR
An implant includes an interface and a wing that is coupled to the interface. A catheter is transluminally advanceable to a heart chamber upstream of a heart valve of a subject and houses the implant. A delivery tool comprises a shaft and a driver. Via engagement with the interface, the shaft is configured to (i) deploy the implant out of the catheter such that, within the chamber, the wing extends away from the interface; and (ii) position the implant in a position in which the interface is at a site in the heart and the wing extends over a first leaflet of the valve toward an opposing leaflet of the valve. The driver is configured to secure the implant in the position by driving an anchor through the interface and into tissue at the site. Other embodiments are also described.
Systems and methods for tissue suspension and compression
Suture passer systems for tissue suspension and tissue compression are described. The system can include a shaft and a needle, wherein the needle is freely rotatable with respect to the shaft. The suture may include an overmolded segment. Methods of placing one or more implants, sutures, fastener, bone anchors and other devices are also described. The methods include moving tissue, including the superior pharyngeal constrictor muscle, palatopharyngeal arch, and palatoglossal arch. The methods include hyoid bone suspension.
Coaptation enhancement implant, system, and method
Implants, implant systems, and methods for treatment of mitral valve regurgitation and other valve diseases generally include a coaptation assist body which remains within the blood flow path as the leaflets of the valve move, the valve bodies often being relatively thin, elongate (along the blood flow path), and/or conformable structures which extend laterally from commissure to commissure, allowing the native leaflets to engage and seal against the large, opposed surfaces on either side of the valve body during the heart cycle phase when the ventricle contracts to empty that chamber of blood, and allows blood to pass around the valve body so that blood flows from the atrium to the ventricle during the filling phase of the heart cycle. Separate deployment of independent anchors near each of the commissures may facilitate positioning and support of an exemplary triangular valve body, with a third anchor being deployed in the ventricle. An outer surface of the valve body may accommodate tissue ingrowth or endothelialization, while a fluid-absorbing matrix can swell after introduction into the heart. The valve body shape may be selected after an anchor has been deployed, and catheter-based deployment systems may have a desirable low profile.
FLEXIBLE SYSTEM FOR DELIVERING AN ANCHOR
A system and associated method for manipulating tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders or other purposes. In one aspect, the system includes a delivery device including a flexible portion that is suited to access target anatomy. The flexibility of an elongate portion of the delivery device can be varied. Additionally, the delivery device can include structure that maintains the positioning of the delivery device in patient anatomy.
HEART VALVE REPAIR
An example medical system includes a medical device configured to join the edges of the leaflets together, an elongate body configured to be navigated through vasculature to a heart valve of patient, and a plurality of tissue engagement devices extending from a distal end of the elongate body, each tissue engagement device comprising at least one clamp configured to capture leaflets of the heart valve.
