  • Patent number: 11986388
    Abstract: Embodiments hereof relate methods of delivering a valve prosthesis to an annulus of a native valve of a heart. A valve delivery system is introduced into a ventricle of the heart via a ventricular wall of the heart. The valve delivery system has a displacement component at the distal portion thereof. The valve prosthesis is in a delivery configuration and the displacement component is in a delivery state in which the displacement component has a first outer diameter. While the valve prosthesis is in the delivery configuration, the displacement component of the valve delivery system is radially expanded into an expanded state in which the displacement component has a second outer diameter greater than the first outer diameter. The valve delivery system is advanced towards the annulus of the native valve of the heart with the displacement component in the expanded state to displace chordae tendineae.

  • Patent number: 11980541
    Abstract: Cartridges configured to hold anchors and associated locking sutures and a common suture used in an array of anchors. A suture anchor array is connected in series by a single working suture and each of the suture anchors allows tensioning of the working suture between itself and the prior anchor implanted in the serial string. Further, each anchor includes a suture lock having a free tail that can be pulled to lock the working suture in place subsequent to tensioning. This creates an independently tensioned suture bridge between each implanted suture anchor and the just previously implanted anchor. The cartridges are configured to securely hold an individual anchor and store the tail of the suture lock, while allowing flossing of anchors along the common suture.

  • Patent number: 11964111
    Abstract: Embolization particles can be safely delivered to the left gastric artery of a patient by introducing the distal end of a catheter in the patient's left gastric artery, inflating a balloon located near the distal end of the catheter so that the balloon prevents blood from flowing through the left gastric artery, and injecting a mixture of particles and contrast agent into the proximal end of the catheter so that they flow through the catheter. In addition, a path is provided for blood to flow into the catheter through an opening in the sidewall of the catheter at a position that is proximal to the balloon, and out through the distal end of the catheter. This blood flow helps to carry the particles along to their destination in the distal portion of the left gastric artery. The particles are also prevented from flowing into portions of the patient's artery system that are proximal of the balloon.

  • Patent number: 11957355
    Abstract: Vascular access devices, systems, and methods of their use are provided. In one embodiment, a vascular access device includes a catheter, a balloon, and an inflation lumen. The catheter includes an elongate flexible shaft having a proximal end and a distal end with a primary lumen therethrough. The balloon is disposed about the distal end of the catheter. The inflation lumen is in fluid communication with the balloon and extends toward the proximal end of the shaft of the catheter. The balloon is inflatable into a shape having a first open end, a second open end, a sidewall between the first and second open ends, and a passageway therethrough, which, when the balloon is deployed and inflated within a vessel, permits blood flowing in the vessel to flow through the passageway.

  • Patent number: 11911024
    Abstract: A slip knot suture construct system and method for securing multiple limbs of suture. The system includes a suture construct having a length of suture including a standing limb with a standing terminal end and a closing limb with a closing terminal end. The suture construct has three loops: a primary loop formed in the closing limb, the primary loop and closing limb extending to the standing limb, a secondary loop formed in the standing limb, and a locking loop formed in the length of suture between the primary loop and the secondary loop. A limb of suture extends through the primary loop. The limb of suture is secured in the suture construct by pulling the closing terminal end proximally, which pulls the primary loop holding the limb of suture through the locking loop and at least partially into the secondary loop.

  • Patent number: 11903813
    Abstract: An intraosseous screw for deposit into a bone structure and retaining a soft tissue therein. The intraosseous screw includes a body and a retention member. The body defines an axial cavity in which soft tissue can be deposited and a window that permits the soft tissue to contact the bone structure in which the intraosseous screw is deposited. The retention member is positioned within the axial cavity and at least partially defines an opening through which a suture connected to soft tissue can pass to facilitate anchoring of the soft tissue within the axial cavity. The intraosseous screw can be combined with a passing suture, driver, and/or peg to provide a system for associating soft tissue with a bone structure. The intraosseous screw can be utilized in a method in which soft tissue is deposited into a bone structure after the interosseous screw is fully deposited in the bone structure.

  • Patent number: 11896215
    Abstract: An Achilles tendon repair device comprises a handle for physician gripping and base having a first set of tendon rods disposed in an arcuate or U-shaped pattern about the base to engage the posterior surface of the tendon and impart a contour, or drape, the tendon in the posterior-anterior plane to increase the surface area for suturing. A second set of suture guide rods extend from the sides of the base and are spaced apart to allow insertion of suture needles along the entire length of the suture guide rods, and at any angle. A suture needle housing guide can be slidingly attached to the suture guide rods and includes sidewalls with predefined suture holes/angles. An adjustable clamping arm can engage the tendon's posterior surface such that the device grasps the tendon on both the anterior and posterior tendon surfaces simultaneously, while increasing posterior-anterior plane surface area to facilitate suturing.

  • Patent number: 11883292
    Abstract: Delivery systems, methods and associated devices to facilitate delivery and deployment of a heart implant. Such delivery systems and methods of delivery include use of a pair of magnetic catheters, including an anchor delivery catheter carrying an anchor, which can be stacked with or can be axially offset from the magnetic head. Such systems further include use of a puncturing guidewire advanceable through the magnetic head of the anchor delivery catheter to establish access to a chamber of a heart and which is attached to a bridging element such that continued advancement of the guidewire draws a bridging element attached to the first anchor across the chamber of the heart while the bridging element remains covered by the magnetically coupled catheters. Methods and devices herein also allow for cutting and removal of a bridge element of a deployed heart implant.

  • Patent number: 11877738
    Abstract: Methods and systems are provided for securing tissue to bone. A surgical system can include a driver device, an elongate shaft receivable within the driver device and having a dilator feature at its distal end, and a capture suture extending through the shaft such that the capture suture's terminal end portions extend to a more proximal position on the driver and the capture suture forms a loop that extends through an opening formed through a side of the shaft. The loop is configured to receive at least one retention suture therethrough and can be tightened by pulling the capture suture's terminal ends, thereby coupling the retention suture with the suture anchor. Once the shaft is inserted into bone and the loop with the retention suture is closed, the suture anchor is driven distally towards the dilator features and into the bone to secure the retaining suture in the bone.
