Patent number: 8623048Abstract: An apparatus and a method for surgical suturing with thread management. An apparatus for tissue suturing including a cartridge having a suturing needle having a pointed end, a blunt end, the suturing needle capable of rotating about an axis; a pusher assembly comprising a cartridge holder having a needle rotation drive capable of releasably engaging the cartridge and rotating the suturing needle about the axis; and an actuator capable of releasably engaging the needle rotation drive to rotate the needle rotation drive. A method for suturing tissue including placing a suturing device having a cartridge containing a suturing needle to span separated tissue segments; activating an actuator to cause rotational movement of the suturing needle through the separated tissue segments; and deactivating the actuator to stop an advancing movement of the suturing needle to cause a suturing material to be pulled through the separated tissue segments forming a stitch.Type: GrantFiled: August 3, 2011Date of Patent: January 7, 2014Assignee: EndoEvolution, LLCInventors: Gerald I. Brecher, John C. Meade, Niall Deloughery, James H. Bleck

Publication number: 20130261643Abstract: A tissue closure device includes a pusher assembly having a drive arm extending from a drive shaft and a drive mechanism at a distal end of the drive arm, wherein the drive mechanism is capable of releasably engaging and rotating a suturing needle having a pointed end and a blunt end about a rotational axis and a cartridge having a protective housing and the suturing needle, the cartridge extending from a distal end of a cartridge holder assembly and releasably attached to the cartridge holder assembly. A pointed end of the suturing needle may be positioned within the protective housing before and after a complete rotation of the suturing needle about the rotational axis. A removable electronic module may be provided controlled by an actuator that mechanically engages the drive shaft to rotate the drive shaft and the drive mechanism, thereby rotating the suturing needle about the rotational axis.Type: ApplicationFiled: May 23, 2013Publication date: October 3, 2013Applicant: ENDOEVOLUTION, LLCInventors: John C. Meade, Douglas M. Macarthur, Stephen M. Blinn, Christopher Sauliner, Brian R. Edwards

Patent number: 7993354Abstract: Devices and methods for minimally invasive suturing are disclosed. One suturing device for minimally invasive suturing includes a proximal section a distal end, and an intermediate region therebetween. The device includes a suture head assembly having a suturing needle with a pointed end and a second end. The suturing needle is capable of rotating about an axis approximately perpendicular to a longitudinal axis of the device, wherein the pointed end of the suturing needle is positioned within the suture head assembly prior to deployment of guides that are adapted and configured to guide the needle around a circular path when advanced by a drive mechanism having a needle driver for engaging and rotating the suturing needle.Type: GrantFiled: October 21, 2010Date of Patent: August 9, 2011Assignee: EndoEvolution, LLCInventors: Gerald I. Brecher, John C. Meade, John Aho, Roger Baske, James H. Bleck, John F. Carlson, Thomas Eagan, Michael J. Helander, James W. Murray, Ashley Perkins, Wayne A. Shakal, Jonathan Towle

Patent number: 7976555Abstract: The invention includes a needle loader that may be used with a suturing device. The needle loader includes a generally planar needle supporting surface, a hub configured and adapted for receiving a generally toroidally shaped suturing needle around the hub, and means for retaining a suturing needle in a fixed toroidal rotational position with respect to the hub about a center axis of needle rotation. Generally, a needle mounted around the hub is selectively disposable on and removable from the hub. In accordance with a further aspect, the loader may further include an opening for retaining suture material attached to a suturing needle. The opening may include a groove defined through the needle supporting surface. The needle loader may further include a guard for preventing access to the point of a suturing needle to protect the needle and/or to prevent accidental needle sticks.Type: GrantFiled: July 17, 2008Date of Patent: July 12, 2011Assignee: EndoEvolution, LLCInventors: John C. Meade, Gerald I. Brecher
