Publication number: 20160256304Abstract: A stent graft delivery device that is pre-loaded with a single guide wire for both tracking the device within a main vessel as well as for cannulating one or more branch vessels is described. The delivery device comprises a delivery catheter having a prosthesis releasably secured thereto and a nose cone extending from the proximal end of the catheter. In a delivery configuration, a secondary catheter is coaxial with the guide wire and extends through at least a portion of the prosthesis lumen and is held within a channel formed in the nose cone. In a released configuration, secondary catheter and guide wire are retracted distally out of the channel formed in the sidewall of the nose cone dilator and can be manipulated for cannulating a branch vessel.Type: ApplicationFiled: January 29, 2016Publication date: September 8, 2016Applicant: COOK MEDICAL TECHNOLOGIES LLCInventors: Blayne A.

Patent number: 9433462Abstract: A system for closing a wound tract after performing a percutaneous procedure is provided. The system includes a closure mechanism having a pair of arm portions that are arranged to adjust between an open and closed position. The closure mechanism includes an electrode that is electrically connected to a power source configured to provide an electrical current or waveform to the electrode. The closure mechanism can be delivered to the wound tract, where the arm portions are adjusted to their open configuration. The arm portions can be moved into engagement with the tissue surrounding the wound tract, where the arm portions can be opened further or closed to reduce the size of the wound tract. The waveform can be applied to the electrode to cauterize the wound, and the closure mechanism can be retracted.Type: GrantFiled: March 12, 2013Date of Patent: September 6, 2016Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Benjamin Marchi, Jarin Kratzberg

Patent number: 9198787Abstract: A delivery system may include a stent-graft, a locking member, and one or more diameter reducing members. The stent-graft may include a tubular graft comprising first and second longitudinally extending sides disposed opposite each other and connected at a tangent line. When the locking member is in a locked position, the locking member restrains a surface of the graft against the cannula. The first diameter reducing member may be slidably connected to a first portion of the graft that is disposed proximate the tangent line and may be slidably connected to a second portion of the graft that is spaced circumferentially away from the tangent line. When the first diameter reducing member is in a restrained position, the second portion of the graft is drawn toward the first portion of the graft and the proximal portion of the stent-graft has a reduced diameter configuration with at least two lobes.Type: GrantFiled: December 20, 2011Date of Patent: December 1, 2015Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Jarin Kratzberg, William Kurt Dierking, Sharath Gopalakrishnamurthy, Blayne A.
