  • Patent number: 10531868
    Abstract: Multiple vascular wall penetrations are formed and sealed in a single blood vessel, typically a vein, for performing cardiac and other catheter-based procedures. Access sheaths are placed in two or more tissue tracts each having a vascular wall penetration at a distal end and into a lumen of the blood vessel. A catheter is advanced though each of the access sheaths to perform a therapeutic or diagnostic procedure. A vascular closure device is introduced through each access sheath, typically sequentially, and an occlusion element at a distal end of the device is deployed against an inner wall of the blood vessel in a manner so that the adjacent access sheath does not interfere or overlap with the deployed occlusion element. The vascular penetration at the distal end in that tissue tract may then be sealed prior to using another vascular closure device to seal a caudally adjacent vascular wall penetration.

  • Patent number: 10335141
    Abstract: A suturing device, and methods for suturing various sizes of apertures in tissues, are presented. The suturing device has a body with at least one or more adjustable arms that are coupled with catch targets. The arms are coupled with needle guides such that movements of the arms orient the needle guides to direct the needles towards the catch targets. The catch targets are coupled with sutures, such that when the needles reach the targets, they capture and pull the sutures back to the body. By changing the angles at which the arms extend from the body, the catch targets are moved closer to, or farther from, the body, and the suture device is readily configured to suture various sizes of apertures.

  • Patent number: 10327747
    Abstract: Apparatus for sealing a vascular wall penetration disposed at the end of the tissue tract comprises a shaft, an occlusion element, a hemostatic implant, and a protective sleeve. The apparatus is deployed through the tissue tract with the occlusion element temporarily occluding the vascular wall penetration and inhibiting backbleeding therethrough. The hemostatic implant, which will typically be a biodegradable polymer such as collagen carrying an anti-proliferative agent or coagulation promoter, will then be deployed from the sealing apparatus and left in place to enhance closure of the vascular wall penetration with minimum scarring. The implant may be radiopaque to allow observation before release.

  • Patent number: 10321910
    Abstract: Transluminal access system includes a stent delivery catheter having a handle control mechanism. The catheter comprises a number of components for establishing an initial penetration between adjacent body lumens and subsequently implanting a stent or other luminal anchor therebetween. Manipulation of the stent components is achieved using control mechanisms on the handle while the handle is attached to an endoscope which provides access to a first body lumen.

  • Patent number: 10314567
    Abstract: An apparatus for sealing a puncture through tissue having an introducer sheath therein includes an elongate positioning member including a housing on a proximal end and an expandable member on a distal end, and a cartridge advanceable along the positioning member from a proximal position to a distal position. The cartridge includes a tubular member including a sealant and an advancer member disposed within lumen of the tubular member. A sleeve is slidably disposed over the tubular member distal end such that, when the tubular member is advanced over the positioning member, the tubular member distal end enters the introducer sheath while the sleeve is stopped and slides over the tubular member to expose the tubular member distal end within the introducer sheath. The introducer sheath and cartridge are then withdrawn, exposing the sealant within the puncture.

  • Patent number: 10314586
    Abstract: The present disclosure relates to repair devices, repair systems, and methods for repair of regurgitant tricuspid valves. A repair method includes positioning a repair device at a tricuspid valve. The repair device includes a pair of proximal arms and a pair of corresponding opposing distal arms, with each proximal arm and corresponding opposite distal arm forming an arm pair. The arms are actuated so that leaflet tissue is grasped between the proximal and distal arms, with a first leaflet being grasped by a first arm pair and a second leaflet being grasped by a second arm pair. A suture line is anchored at the second leaflet. Then, the repair device is pivoted to grasp and suture a third tricuspid leaflet to tie the second and third leaflets together. The clip remains deployed to tie the first and third leaflets together.

  • Patent number: 10231737
    Abstract: Implantable occlusion devices that include one or more flanges extending from a tubular body are disclosed. The flange or flanges may assist in retention of the device within a vessel, cavity, appendage, etc. At least one flange on the occlusion device may include a concave surface proximate one end of a body. Because of the shape of the flange, e.g., its concavity, the occlusion device may resist dislocation due to e.g., the forces generated within the left atrial appendage during atrial filbrillation.

  • Patent number: 10219796
    Abstract: A device for percutaneous transcathetral closure of Atrial Septal Defect by deploying a pericardial patch without ardiopulmonary bypass includes a guide, and a head including a distal jaw and a proximal jaw. The guide includes guide knobs which move guide levers of the guide forward and backward via a rod and control the head. Each of the distal jaw and the proximal jaw includes a plurality of alms which closes when a distal disc moves forward and a proximal disc moves backward. The aims of the distal jaw and the arms of the proximal jaw open through a pressure when the distal disc moves backward and the proximal disc moves forward. When the arms of the distal jaw and the aims of the proximal jaw are completely open, pins located on the arm of the distal jaw engage with sockets located on the arm of the proximal jaw.

  • Patent number: 10219904
    Abstract: Medical devices, systems, and methods reduce the distance between two locations in tissue, often for treatment of congestive heart failure. In one embodiment an anchor of an implant system may reside within the right ventricle in engagement with the ventricular septum. A tension member may extend from that anchor through the septum and an exterior wall of the left ventricle to a second anchor disposed along an epicardial surface. Deployment of the anchor within the right ventricle may be performed by inserting a guidewire through the septal wall into the right ventricle. The anchor may be inserted into the right ventricle over the guidewire and through a lumen of a catheter. An anchor force may be applied within a desired range to secure the anchors about the septum and epicardial surface. The anchor force may inhibit migration of the anchors relative to the septum and epicardial surface.

  • Patent number: 10219797
    Abstract: A wound closure apparatus can be a self-contained device for delivery and deployment of a tissue engineered wound plug that can secure fascial closure of laparoscopic port-site wounds. The wound plug can include a subfascial rivet head, a suprafascial rivet head, and a compressible column. Once in the wound, the wound plug may be deployed with the subfascial rivet head below the fascia of the wound and the suprafascial rivet head above the fascia of the wound. As this occurs, the column of the wound plug can be stationed within the opening of the wound. Once the wound plug is secured above, below, and within the fascial defect, the rivet heads may be interlocked within an inner channel of the column and remaining elements of the apparatus may be removed and discarded.

  • Patent number: 10206668
    Abstract: The provided technologies provide an implant closure device having a mesh layer formed on a flexible substrate, collectively forming a sealable member, that improves a seal formed over an aperture in a body lumen. The mesh facilitates a faster and more secure adherence of the sealable member to the surrounding edges at the puncture site. Furthermore, the provided technology may promote platelet-capture and encourage localized platelet aggregation at the exposed collagen in the wound edges on the mesh layer. The platelet impregnated mesh layer can facilitate cellular adhesion, enabling the sealable member that is local to the wound opening to act, in essence, as a “biological glue”.
