  • Patent number: 9078633
    Abstract: A vessel access and closure device places a running suture in the wall of a blood vessel using a rotating helical suture needle that carries the suture along a helical path passing through the vessel wall, then reverses rotation to release a suture anchor attached to the distal end of the suture. A loose helical coil of suture is left behind as the helical suture needle withdraws. The device is withdrawn and replaced with a vessel dilator and an introducer sheath that opens up a larger access opening into the blood vessel and creates a pathway that passes though the helical coil of suture for introducing an interventional device into the blood vessel. After the interventional procedure is completed, the interventional device and the introducer sheath are withdrawn and the running suture is tightened and secured with a suture lock to close the access opening into the vessel.

    Abstract: A surgical filament snare assembly including an anchor capable of being fixated in bone and having a filament engagement feature. A first filament has a noose on a first portion of at least a first limb and has a second portion connected to the filament engagement feature of the anchor. Preferably, at least one free filament limb, which in some embodiments is a length of the first filament and in other embodiments is a second filament, is capable of being passed through tissue to be repaired and has at least one end passable through the noose to enable incremental tensioning of the tissue after the anchor is fixated in bone. The noose strangulates the free filament limb when tension is applied to at least one of the free filament limb and the noose.

  • Patent number: 8784437
    Abstract: The present invention relates to a tissue securement system, device and method for endoscopy or endosonography-guided transluminal interventions whereby a ligation or anchor is placed and secured into soft tissue. An objective of this invention is to provide a method to reduce gastroesophageal reflux by endosonography-guided intervention. Specifically, endosonography is used to insert a ligation element through the esophageal wall, through the diaphragmatic crus and into the fundus of the stomach. This ligation element placed from the esophagus and around the Angle of His to create a barrier to gastroesophageal reflux.

  • Publication number: 20140155914
    Abstract: A suture passer device is provided including a jaw configuration that grasps targeted tissue such as tendons or muscles in a similar manner as existing suture passer devices; however, the device introduces the needle and the attached suture along the axis of the shaft of the device. After grasping the targeted tissue, the needle is deployed by manipulating the handle of the device similar to conventional suture passers however, the needle is deployed in between the opposing jaws and the needle is advanced into tissue along the axis of the shaft as opposed to perpendicular to the shaft as in prior art devices. The invention further includes methods of deploying sutures and anchors. The invention also includes embodiments of jaw designs, and various embodiments of suture passing needles, sutures constructions, and anchor designs. Therefore, the invention also comprises the device in combination with the needles, sutures, and anchors, as well as the needles, sutures, and anchors in separate sub combinations.

  • Publication number: 20140081320
    Abstract: Methods and devices are provided for securing tissue to bone. In general, a suture leader can have leading and trailing ends, and an inner passageway configured to receive a strand of suture therein. More specifically, the trailing end of the leader can be configured to receive the strand of suture therein to form an overlapping region of suture leader and suture. When the suture is positioned in the leader, an outer diameter of the leading end of the leader can be less than an outer diameter of the over lapping region. The leader can have a lower bending stiffness than the suture so that the leader can be more easily folded into a bend. In certain aspects, the suture leader can be formed from a substantially flexible, braided material so that the leader can be configured to contract when a pulling force is applied to the leader. In another embodiment, the suture leader can have a pre-formed crease configured to mate with a threading tool.

  • Publication number: 20140074126
    Abstract: Suturing systems and needle removal devices for more efficiently removing needles from suturing systems are provide. In some embodiments, a suturing system guide body includes one or more needle lumens that transfer corresponding needles circumferentially around the guide body. Thus, when the needles exit the needle lumens at the proximal end of the guide body, the needles are in closer proximity to one another for removal. Other embodiments include various needle capture devices tools used for removing needles from a suturing system. Needle capture devices and tools can include needle receptacles positioned and configured to generally correspond to the needle lumens of the suturing system. The needle receptacles may be further configured to selectively receive and grasp onto one or more needles extending proximally from the needle lumens of the suturing system.

  • Patent number: 8663242
    Abstract: The invention essentially relates to a surgical needle (17) comprising a long hollow body (18) and two ends (19, 20). The body (18) comprises a ventral wall (21) and a dorsal wall (22) which are connected to one another. According to the invention, the dorsal wall (22) and the ventral wall (21) extend along the long axis of the needle (17). Each of the two ends (19, 20) comprises a hollow beveled tip (23, 24). The needle (17) also comprises a hole (25) which is provided in the dorsal wall (22) of the body (18) and a slit (26) which is provided in the ventral wall (21). In this way, a suture (30) can slide inside the hollow body (18) of the needle, the suture being retained in position by the knot (29) or means for stopping thereof. For said purpose, the smallest diameter (27) of the hole (25) is greater than the largest width (28) of the slit (26).
