Patent number: 10149676Abstract: 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.Type: GrantFiled: March 4, 2014Date of Patent: December 11, 2018Assignee: INCUMEDx, Inc.Inventors: Gregory Edwin Mirigian, Be Thi Le, Brendon James Bolos, Berchell John Yee, Amiel Richard Aguilar, Regina Coeli Velasco, Crystal Kay Sein Lwin, Liem Ho

Patent number: 8298251Abstract: 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.Type: GrantFiled: February 27, 2008Date of Patent: October 30, 2012Assignee: Medtronic, Inc.Inventors: Steve Golden, Laurent Schaller, Demetri Mavroidis, Stephen Ainsworth, Kathleen Woodside, Liem Ho

Patent number: 8177836Abstract: 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.Type: GrantFiled: March 10, 2009Date of Patent: May 15, 2012Assignee: Medtronic, Inc.Inventors: Anthony Lee, Jasper Jackson, Liem Ho
