Publication number: 20160287230Abstract: A tool for closing an opening in tissue may include a catheter, a clasp applicator positioned substantially at the distal end of the catheter; and at least one clasp held by the clasp applicator, where the clasp may include a plurality of tines and be plastically splayable by the clasp applicator. A patent foramen ovale in heart tissue may by closed by, for example, advancing that exemplary clasp applicator through the patient's vasculature to a location in proximity to the patent foramen ovale, anchoring the clasp applicator with respect to the patent foramen ovale, splaying the clasp, advancing the splayed clasp into contact with tissue; closing the clasp, and removing the clasp applicator from the heart.Type: ApplicationFiled: June 9, 2016Publication date: October 6, 2016Inventors: Bernard A.

Patent number: 8574246Abstract: An integrated anastomosis tool may include an effector that both makes an opening in the wall of a target vessel and connects a graft vessel to the target vessel. The effector may include a cutter assembly and a connection module that are independently actuatable. The connection between the graft vessel and the target vessel may be compliant, and may be achieved by suturing an end of the graft vessel to the side of the target vessel with the connection module.Type: GrantFiled: December 3, 2004Date of Patent: November 5, 2013Assignee: Cardica, Inc.Inventors: Theodore M.

Patent number: 7883518Abstract: A length of suture is provided, and a knot is partially tied in that suture around a tube. The partially-tied knot includes a noose portion connected to a loosely-tied barrel portion. The knot is tied by holding a standing end of the suture substantially stationary and pulling the running end of the suture through the noose. The knot locks upon tightening, making it suitable for surgical applications.Type: GrantFiled: January 7, 2005Date of Patent: February 8, 2011Assignee: Cardica, Inc.Inventors: Kathleen H.

Patent number: 7727245Abstract: One method for closing an opening in tissue may include providing a substantially continuous solid staple having a plurality of tines and a longitudinal centerline, plastically deforming the staple to a splayed configuration; penetrating at least one tine into tissue in proximity to the opening; and plastically deforming the staple to a closed configuration. Another method for closing an opening in tissue may include providing a staple having a plurality of tines; plastically deforming the staple to a splayed configuration by applying force in the distal direction against a proximal surface of the staple; penetrating at least one tine into tissue in proximity to the opening; and plastically deforming the staple from the splayed configuration to a closed configuration by applying force in the distal direction against a proximal surface of the staple.Type: GrantFiled: January 11, 2008Date of Patent: June 1, 2010Assignee: Cardica, Inc.Inventors: Theodore M. Bender, Zachary Warder-Gabaldon, Matthew B. Newell, Bernard A. Hausen, Brian R. DuBois, Bryan D. Knodel
