  • Patent number: 11399815
    Abstract: Vascular closure devices and methods for closing a blood vessel puncture site disposed at a distal end of a tissue tract are described. A combination of the body's own natural mechanism with chemical and/or biological agents is relied upon to accelerate the hemostatic process. Included are steps of introducing a closure device through the tissue tract and deploying an expansible member at a distal end of the device within the blood vessel to occlude the puncture site. A sealing member disposed proximal the expansible member is then displaced by retracting and tensioning a coil spring so as to expose a chemical and/or biological region or release region of the device. The retraction and tensioning of the coil spring is limited by a coupling member. Exposure of blood and tissue to the chemical and/or biological sealing member promotes the clotting processing to accelerate the occlusion process in the tract.

The coil is made of a shape memory alloy (SMA) and is adapted to exert a compressive force upon layers of tissue caught between the inner loops of the coil. The magnets are adapted to provide additional compressive force to adjacent inner loops of the coil, thereby further causing the coil to cut through the layers of tissue and create a shunt. The diameter of the resultant shunt is less than the diameter of the outer loops, thereby preventing the outer two loops from passing through the created shunt. At least one end of the coil has a connection means for connecting with a delivery device.

  • Patent number: 11172976
    Abstract: A catheter-based device tracks over a guidewire which has been placed from a first blood vessel into a second blood vessel. The distal tip of the catheter is advanced into the second vessel while a proximal member remains in the first vessel. Matching blunt tapered surfaces on each of the distal tip and the proximal member are clamped together, with adjacent walls of each vessel between them, after which a known, controlled pressure is applied between the two surfaces. Heat energy is then applied to the blunt surfaces for approximately 1-30 seconds to weld the walls of the two vessels together. After coaptation of the vessel walls, the heat is increased to then cut through the vessel walls to create a fistula of the desired size.

  • Patent number: 11141161
    Abstract: Disclosed embodiments include apparatuses, systems, and methods for facilitating anastomosis between bodily passages. In an illustrative embodiment, an eversion mechanism is configured to engage a first external surface of a receiving passage adjacent a first opening in the receiving passage in order to create a receiving flange presenting a first interior face. A donor support mechanism is configured to support a donor passage with an opening in an end in an everted position that forms a donor flange presenting a second interior face. The donor support mechanism is further configured to present the second interior face of the donor flange against the first interior face of the receiving flange to present a passage juncture. A suturing mechanism is configured to motivate a filament through a helical path around the passage juncture to suture the second interior face of the donor passage to the first interior face of the receiving passage.

  • Patent number: 11141301
    Abstract: An apparatus for the treatment of acid reflux disease has an implantable movement restriction device adapted to be at least partly invaginated by a patient's stomach fundus wall. A substantial part of the outer surface of the movement restriction device is adapted to rest against the stomach wall without injuring the latter in a position between the patient's diaphragm and at least a portion of the lower part of the invaginated stomach fundus wall, such that movement of the cardiac notch of the patient's stomach the patient's diaphragm is restricted, to thereby prevent the cardia from sliding through the patient's diaphragm opening into the patient's thorax, so as to maintain the supporting pressure against the patient's cardia sphincter muscle exerted from the patient's abdomen. The movement restriction device has a size of at least 125 mm3 and a circumference of at least 15 mm.

  • Patent number: 11134949
    Abstract: The present invention relates to a device for endoscopy or endosonography-guided transluminal interventions whereby two luminal structures in the body may be drawn toward each other and a fluid conduit formed in between. The device may have a hollow central member to which is coupled a distal retention member and in one embodiment a proximal retention member. The retention members may each be positioned inside one of the luminal structures and expanded from a first condition to an expanded second condition having an increased radius. The length of the central member may be shortened and its diameter expanded to approximate the two retention members and thereby the luminal structures.

  • Patent number: 11065140
    Abstract: Methods, apparatuses and systems are described for expandable stent delivery apparatus to cover an access site. The method may include delivering a stent delivery system through an access site, where the stent delivery system comprises a positioning member with a first portion that is rotatable with respect to a second portion, and where the stent is releasably coupled with the first portion of the positioning member. In some cases, the method may further include withdrawing an outer constrainment member from the stent to deploy a proximal portion of the stent within the body lumen and rotating the proximal portion of the stent away from the access site by withdrawing the positioning member proximally and back through the access site. The method may further include covering the access site with the proximal portion of the stent upon fully deploying the proximal portion from the outer constrainment member.

  • Patent number: 11033271
    Abstract: Disclosed embodiments include apparatuses, systems, and methods for facilitating surgical anastomosis. In an illustrative embodiment, an apparatus includes a first connector configured to engage an opening of a donor passage. A second connector is configured to engage an opening in a receiving passage. A separator is configured to support the first connector and the second connector and to fix relative positions of the end of the donor passage to edges of the opening in a receiving passage across a gap. The separator is configured to maintain the gap between the first connector and the second connector while multiple loops of a suture are passed through the edge of the opening in the donor passage and the edges of the opening in the receiving passage. The first connector, the second connector, and the separator are further configured to be removed from between adjacent loops of the multiple loops of the suture.

  • Patent number: 11020256
    Abstract: Systems and methods to provide end to end stabilization support to the operational catheter and reduce the need to stabilize or push from the lateral wall of the aorta during coronary interventions. This reduces the potential for stroke from plaque breaking off the wall of the aorta during intervention procedures. A support and stabilization wire having one end at the femoral percutaneous access and the second end at a radial percutaneous access is established for end to end stabilization. A bifurcated catheter having a wide lumen for procedural catheters and a narrow lumen for the support wire or catheter is advanced over the support wire to the aortic arch. A procedural catheter and a variety of different shaped guide wires may be deployed from the wide lumen of the bifurcated catheter into the right or left coronary artery to accommodate a range of aortic anatomical considerations during the coronary interventions.
