  • Patent number: 10149676
    Abstract: A device for delivering an implant to a vascular disorder of a patient includes a delivery pusher. A stationary blade may be coupled to the delivery pusher. The stationary blade may include a sharp and stationary cutting component for cutting through a suture coupling the implant to the delivery pusher and for thereby releasing the implant when placed in proximity to the vascular disorder. In some cases, the strength of a junction connecting the suture to the implant is equal to or greater than the tensile strength of the suture itself. Additionally, or alternatively, a detachment handle may be fixedly and permanently attached to the delivery pusher such that a user of the device need not couple the detachment handle to the delivery pusher. The detachment handle may include a user manipulable component for initiating a mechanical release of the implant when placed in proximity to the vascular disorder.

  • Patent number: 8298251
    Abstract: A system for anastomosing a first tubular structure to a second tubular structure having an opening formed therein comprises a support device having a plurality of arms forming spaces therebetween and a plurality of piercing members slidably coupled to the arms. The support device piercing members have a retracted state and an extended state to support the first tubular structure thereon for placement within an opening in the second tubular structure to facilitate anastomosing the tubular structures together. The arms can be configured to urge the first tubular structure against the portion of the second tubular structure surrounding the opening to form a seal therebetween. According to one embodiment, a plurality of discrete fasteners are provided to pass through the support device spaces and the first and second tubular structures. In another embodiment, fasteners are integrated into the support device and releasably coupled thereto for delivery to the anastomosis site.

  • Patent number: 8177836
    Abstract: A surgical fastening apparatus including at least one self-closing clip and a deployment device. The self-closing clip comprises a wire defining an intermediate portion interconnecting opposing, first and second side portions having a memory set loop shape. The deployment device includes a clip holding assembly and an actuator. The clip holding assembly includes first and second containment arms and a transfer rod. The containment arms have a distal segment defining a lumen extending from an open, distal end. The transfer rod is associated with at least one of the containment arms in an axially movable fashion and forms an engagement feature. The actuator is connected to the transfer rod for controlling movement of the rod. Upon final assembly in a pre-deployment state, the engagement feature of the transfer rod engages the intermediate portion of the clip, and the side portions are captured by the containment arms.

  • Publication number: 20110092989
    Abstract: Surgical connection apparatus comprises a support having a proximal portion with a distal end and a proximal portion. The support forms a pathway between the proximal and distal portions. A plurality of self-closing clips are slidably disposed in the pathway and a pusher is arranged to slidably move in the pathway and push the clips in a distal direction. The apparatus facilitates partial ejection of a clip after which the remainder of the clip is withdrawn therefrom. In one embodiment, the support comprises a tubular needle with the distal end being pointed. The needle can be used to penetrate the tissue or material to be joined and to manipulate or approximate tissue or material to he joined before the clip is partially ejected.
