  • Publication number: 20210038247
    Abstract: The present embodiments provide apparatus and methods for treating tissue by applying a force to the tissue. In one embodiment, the apparatus comprises a deployable segment having proximal and distal regions, a main body extending therebetween, and a loop member formed at the distal region of the deployable segment. A cannula having a bore is dimensioned to circumferentially surround at least a portion of the main body at a location proximal to the loop member, and a spring member is disposed between the cannula and the loop member. The proximal end of the spring member is affixed to the cannula, and the distal end of the spring member is movable to apply a compressive force to adjust the size of the opening of the loop member and compress tissue disposed within the opening of the loop member. In an alternative embodiment, the cannula is omitted, and a diameter of the loop member is configured to be reduced and increased any number of times before final deployment of the deployable segment.

  • Patent number: 10568614
    Abstract: The present embodiments provide a system for facilitating closure of a bodily opening. In one embodiment, the system comprises an anchor having a deployed state dimensioned for engaging tissue surrounding the opening, a first tether coupled to the anchor and extending proximally therefrom, and a graft member comprising a first bore disposed therein. The anchor may comprise a width that is larger than a width of the opening such that the anchor is disposed securely within or distal to the opening. The first tether is dimensioned to be disposed through the first bore in the graft member, such that the graft member is advanced distally over the first tether. The graft member then may be secured to the anchor. Various anchor designs are provided along with a supporting framework that may be coupled to the graft member.

  • Publication number: 20190247043
    Abstract: Among other things, there are shown embodiments of locking mechanisms for holding sutures in tension. Such devices may be used with implants that use or require sutures, and are easily locked remotely. In particular embodiments, a lock includes a housing member, a pin member at least partially within the housing member, and a spring biasing the pin member into the housing member. The pin member includes a gripping portion, and has a retracted condition and a locked condition. When retracted, a suture can move through the housing member and around the gripping portion of the pin member. When locked, the gripping portion of the pin member engages the suture and presses it against the interior of the housing member.

  • Patent number: 10076239
    Abstract: A medical system generally comprises a camera head, a beam, and a guide sheath. The camera head is connected to the beam which is bendable in a first direction and resists bending in a second direction opposite the first direction. The guide sheath slidably receives the beam, the beam extending through a distal end of the guide sheath such that the camera head projects from the distal end of the guide sheath. The guide sheath includes first and second sheath portions, and in an operative configuration the first sheath portion is angled relative to the second sheath portion to define a first bend. The beam is oriented relative to the guide sheath such that, as the beam is slid relative to guide sheath, the beam bends in the first direction through the first bend, and a projecting portion of the beam resists bending in the second direction.
