  • Patent number: 11744591
    Abstract: A medical device for an anastomosis is provided. The medical device distinguishes an inner tubular layer, an outer tubular layer, and a support element defining a longitudinal axis. It further distinguishes two or more independent C-rings distributed and positioned at an acute orientation angle relative to the longitudinal axis of the support element at one end of the support element. The support element and the two or more C-rings are embedded in between the inner and the outer tubular layers. The types of applications one could envision are e.g. a proximal anastomosis, distal anastomosis, or side-to-side anastomoses, in a customized pre-fabricated graft. Embodiments of the invention could also be incorporated into an anastomotic connector device design. Embodiments of the invention could further be envisioned as vascular grafts applications such as Coronary Artery Bypass Graft (CABG), dialysis access grafts and peripheral vascular applications.

  • Patent number: 11730476
    Abstract: Described here are systems, devices, and methods for providing remote manipulation or traction to tissue using one or more graspers, delivery devices, and magnetic control assemblies. The graspers may be configured for insertion into the patient during a minimally-invasive procedure, such as a laparoscopic operation. The graspers may be configured to releasably connect to tissue. In some embodiments, the grasper may comprise a clip, a clamp, a suction device, a coil, or the like, and may be configured to connect to any suitable tissue. Delivery devices may be configured to releasably engage a grasper to deliver the grasper, remove it from the patient, or reposition it. The delivery devices may additionally be configured to actuate the grasper to attach it to tissue and/or detach it from tissue. The magnetic control elements may be configured to be positioned externally of the body to move, reposition, and/or hold the grasper.

  • Patent number: 11730515
    Abstract: Systems, devices, and methods are provided for transseptal access of septa within a patient. The device can be advanced to a septum, e.g., towards a fossa ovalis. Instead of applying positive pressure to “tent” the septum, a negative pressure is applied to a lumen within a sheath, e.g., within an elongated member slidable within the sheath, via a negative pressure source such as a syringe on the proximal end of the sheath. This results in the septum pulling inward. The sheath employs a stationary needle-like central core component contained within the lumen of the sheath that punctures the septum when the same is pulled passed it by the negative pressure. The stationary needle-like central core component may be hollow and may form a portion of the elongated member or may be coupled to a distal end thereof.

Methods of placement may be made with sharp, pointed ends, which may be needles, or insertion devices. Sinusoidal patterns of sutures that have amplitudes generally perpendicular to the resultant holding force of the suture are provided.

  • Patent number: 11717278
    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: 11701140
    Abstract: An alternative to using a stent, a catheter apparatus and method removes arterial plaque within an isolated environment at a target site while separately maintaining continuous blood flow, then removed post procedure. A catheter head has a tubular array for providing a plaque treatment solution within a first layer of the catheter apparatus without the same entering the blood stream, and for receiving a guide-wire to position the apparatus at the target site. The first layer has a plurality of flap members, with each defining an air pressure regulated pore for plaque removal using an inflow tube and an outflow tube. A separate second layer of the catheter apparatus accommodates continuous blood flow during the procedure. A third layer of the catheter apparatus contains the selectively inflatable balloon. When the balloon is inflated, the catheter head and the catheter end cap each inflate to supports the arterial wall.

  • Patent number: 11701103
    Abstract: An adjustable, knotless button/loop construct for fixation of ankle syndesmosis tibio-fibular diastasis and an associated method of ankle repair using the same. The knotless construct comprises a pair of buttons attached to a flexible, continuous, self-cinching, adjustable loop integrated with two splices that are interconnected. The knotless construct is passed through fibular and tibia tunnels and the buttons are secured on the cortical surfaces of tibia and fibula. One of the buttons (for example, an oblong button) is secured on the medial side of the tibia by passing the button and the flexible, adjustable loop though the fibular and tibia tunnels and then flipping and seating the button outside the tibia. The length of the flexible adjustable loop is adjusted so that the second button (for example, a round button) is appropriately secured on the lateral fibula.

  • Patent number: 11690645
    Abstract: A method of removing tissue in a body lumen includes advancing a tissue-removing catheter over a guidewire in the body lumen to position a distal end of the catheter adjacent the tissue and a proximal end portion of the catheter outside of the body lumen. The catheter includes an elongate body, a tissue removing element mounted on a distal end portion of the elongate body, and an inner liner disposed within the elongate body. The inner liner defines a guidewire lumen in which the guidewire is disposed during the advancement of the catheter. The method further includes rotating the elongate body and tissue-removing element of the catheter to remove the tissue. Detecting wear of the inner liner caused by the elongate body contacting the inner liner during use.

  • Patent number: 11672526
    Abstract: Various exemplary methods and devices are provided for passing sutures around anatomical structures. In an exemplary embodiment, a suture delivery device is provided that includes a body portion having a suture delivery member disposed therein and configured to pass a suture around an anatomical structure. The suture delivery member can be movable between a retracted configuration in which the suture delivery member is disposed within the body portion and an advanced configuration in which the suture delivery member extends distally beyond the body portion and assumes an arcuate shape. The arcuate shape can correspond to a shape of the anatomical structure and can extend almost all of the way around the anatomical structure, for example at least around 270° of a circle, thus assisting a user in passing the suture around the anatomical structure without having to manually manipulate the suture delivery device at awkward angles around adjacent tissue.
