  • Patent number: 10383658
    Abstract: This disclosure includes surgical anchors and related devices and methods that can be used for surgical bone fracture fixation. Some embodiments involve the use of a polymeric cored braided suture that can be held in place by anchors implanted or inserted into bone on each side of a fracture. In some embodiments, the present anchors can be secured into the bone while maintaining high tension (e.g., relative to certain prior art methods) in the suture during the deployment process. Some embodiments can provide for tensioning (e.g., using a polymeric cored braided suture) to compress the fracture and hold the bone in place, functioning as though the suture has sewn the bone (e.g., fragments or portions) together. This can, for example, provide rigid fixation of a fracture which may be important for healing to occur. The tension preload can provide compression to maintain fixation in the face of tensile and shear loads applied to the bone (e.g., as a result of movement and weight bearing).

    Abstract: A device for creating a fistula between blood vessels operates in conjunction with a guidewire to locate and position itself so that it straddles both vessels and is able to draw them together. A fixing agent is released either from within the device or from an external needle, or both, into the procedural site. The fixing agent functions to hold the relative position of the two vessels, to seal the surrounding tissue so that any leaks that do occur don't spread into the tissue to create a hematoma, and to limit expansion of the fistula. After the vessels are in close proximity to each other and the fixing agent is applied, the device of the invention employs a cutting mechanism which opens a portal between the two vessels.

  • Patent number: 10285702
    Abstract: A bioresorbable drug-eluting biopolymer suture-free blood vessel anastomosis devices can be deployed to join two blood vessels and resorbed by the body over a predetermined time period after the blood vessel has become joined. The anastomosis device can include a hollow tube that is inserted interconnect the two vessels to be jointed. A non-piercing suture is wrapped around the vessel to secure the anastomosis. The anastomosis device can include hollow tube that extends along an axis from a first end to a second end. The ends can be fitted with elements that facilitate mechanical attachment of the vessel to the anastomosis device and provide for a secure seal.

  • Patent number: 10213327
    Abstract: A stent having an axial end to which is attached a ring of spoons of a material different from that of the stent. In one aspect, the ring of spoons is connected to the axial end through a plurality of complementary male-female form-fitting portions. In one aspect, the ring of spoons include parallel straight side edges. In one aspect, each of the side edges lies within a first distance from a facing side edge of an adjacent spoon in a stent delivery configuration, and each of the side edges lies within a second distance, greater than the first distance, from the facing side edge of an adjacent spoon in a stent deployed configuration.

  • Patent number: 10111661
    Abstract: Various exemplary matrix metalloproteinase (MMP) inhibiting adjuncts for surgical devices are provided. In general, an implantable adjunct can be configured to be applied to tissue by a surgical stapler in conjunction with staples. The adjunct can have at least one medicant releasably retained therein that is configured to reduce a length of the epithelialization process. In other words, the at least one medicant releasably retained in the adjunct can be configured to speed up an inflammation stage of wound healing and/or a proliferation stage of wound healing and, accordingly, reduce an amount of time before a remodeling stage of wound healing begins. The at least one medicant can be configured to be released along the staple line defined by the staples.

  • Patent number: 10111667
    Abstract: A system is described for performing vascular anastomosis without the use of sutures. The system includes a connector comprised of memory material and an incision seal. The connector has one end configured to securely engage a graft vessel and another end with wings and barbs. The wings are configured to securely engage an inner wall of a main vessel and the barbs are configured to lock with the incision seal. Once locked, the incision seal and the connector apply a clamping force that secures the graft vessel with the main vessel.

  • Patent number: 10076379
    Abstract: A surgical instrument includes a handpiece, an elongate shaft assembly extending distally from the handpiece, an activation assembly, an end effector disposed at a distal end of the shaft assembly, and a firing beam. The handpiece comprises a cover operable to selectively expose an interior of the handpiece. The activation assembly is selectively coupleable with the handpiece and is operable to regulate the delivery of power to the end effector. The shaft comprises a selectively removable jaw assembly. The end effector has a pivoting jaw operable to pivot toward and away from the jaw assembly to thereby capture tissue. The jaw assembly and the pivoting jaw each comprise an electrode surface. The electrode surfaces are configured to seal the captured tissue by providing RF energy to the tissue. The firing beam is configured to sever the sealed tissue.

  • Patent number: 10058328
    Abstract: An anastomosis device for joining hollow lumens or viscera, suitable for deployment at the surface of two superposed adjacent lumens. The device has a main tubular body of longitudinal axis (L), having first and second open ends and opposite outside and inside faces. The main tubular body has at least three columns of loops and at least three rows of loops and sets of proximal and distal radial projections extending along at least a depth (E) at the peripheries of the first and second ends respectively. The distal and proximal sets are spaced apart by a minimum internal distance (D), and further include a set of intermediate radial projections extending along at most a depth (e) and arranged between the sets of proximal and distal radial projections. The depth (e) is less than (E), and the minimum internal distance (D) is determined so as to receive two superposed adjacent lumens.

  • Patent number: 10034748
    Abstract: A prosthetic aortic valve intended for native or valve-in-valve within bioprostheses includes an expandable support scaffold and valve leaflets disposed within an upper leaflet portion of the support scaffold. The valve leaflets within the upper portion may be located within the annulus (intravalvular), above the annulus, or above the native or prosthetic leaflets (supravalvular). The valve within a previously implanted degenerated heart valve such that a base or lower portion of the replacement valve is within the previously implanted valve and the upper portion is expanded within the aorta, the internal area of the valve can be increased and the hemodynamics of the valve improved. Alternatively, the valve may include separate upper and lower portions allowing the portions to be implanted sequentially if needed and the length and other characteristics of the valve to be adjusted based on patient anatomy and condition.
