Publication number: 20240090883Abstract: Closure devices for sealing a puncture and methods of sealing a puncture are described herein. A closure device may be used to position a sealant in a puncture. The sealant may be provided in a sheath which is retracted to expose the sealant in the puncture. A support member may be advanced to compress the sealant. The device may have a lock that prevents the support member from advancing prematurely. The lock may be unlocked when the sheath is at least partially retracted. The device may have an actuator that controls movement of the sheath and the support member. The lock may remain in a locked position until the sheath is at least partially retracted.Type: ApplicationFiled: July 12, 2023Publication date: March 21, 2024Inventors: Wesley Chung Joe, Sravanthi Avuthu, Curt D. Guyer, Richard Repp, Martin Schnitzer

Patent number: 11832804Abstract: A closure system for delivering a sealant to an arteriotomy. A distal section of the closure system can include overlapping inner and outer sleeves that can expand with expansion of the sealant. A proximal section of the closure system can include a handle portion and a sheath adapter extending from the handle portion. The handle portion can comprise one or more actuators that when depressed or engaged can assist in deployment of the sealant in the arteriotomy and can further include tamping of the sealant and/or retraction of an expandable member. The sheath adapter can removably engage a side port or an irrigation line of a standard procedural sheath. When the sheath adapter is secured to the procedural sheath, movement of the closure system can also move the procedural sheath.Type: GrantFiled: October 24, 2019Date of Patent: December 5, 2023Assignee: ACCESS CLOSURE, INC.Inventors: Ronald Ray Hundertmark, Kevin To, Curt Guyer, Rick Repp, Martin Schnitzer, Sravanthi Avuthu

Publication number: 20220211991Abstract: A method and device for positioning an expandable support in a blood vessel is disclosed herein. The device may include a handle, a catheter assembly, a core wire, and an expandable support. The expandable support may be used to position the device relative to the arteriotomy, as well as to provide temporary hemostasis. The expandable support may be attached to the catheter assembly at a first end, and to the core wire at a second end to optimize the width of the expandable support based on the function being performed by the expandable support at a given time. The catheter assembly may be able to move relative to the handle and the core wire, thereby moving the first end of the expandable support relative to the handle and the core wire.Type: ApplicationFiled: September 27, 2021Publication date: July 7, 2022Inventors: Eric Christopher DAILEY, Sravanthi AVUTHU

Patent number: 10751116Abstract: An energy delivery device for treating a patient includes a probe body; a plurality of guide sleeves positioned inside the probe body and adapted to be deployed radially away from the probe body and into tissue of the patient; and a plurality of elongate electrode elements each adapted to receive electrical treatment energy from an energy source and adapted to be deployed into the tissue through a corresponding deployed guide sleeve. The guide sleeves provide a structural pathway for guiding the electrodes along their intended trajectory and for determining the angle of deployment of the electrodes relative to the longitudinal axis of the probe body.Type: GrantFiled: May 10, 2017Date of Patent: August 25, 2020Assignee: AngioDynamics, Inc.Inventors: Kevin Lee Moss, Meir Hai Moshe, Sravanthi Avuthu, Robert M.

Patent number: 9247946Abstract: A drill sleeve is provided for guiding a bone drill in alignment with the screw holes and drill guides. The drill sleeve includes a cylindrical body having a first end, a second end and a longitudinal axis extending therebetween. The cylindrical body includes a longitudinal bore therethrough that is sized for passage of a bone drill. The drill sleeve also includes a frictional retaining element for exerting a bearing force against the surface of the bone drill, such that the frictional retaining element may support at least the weight of the drill sleeve on the bone drill. The bone drill has graduated indicia, and a portion of the drill sleeve may be referenced relative to the indicia so as to be used as a depth gauge for determining the length of a drilled hole in order to select a screw fastener having the appropriate length.Type: GrantFiled: June 26, 2013Date of Patent: February 2, 2016Assignee: Biomet C.V.Inventors: Cesare Cavallazzi, Marcus Bourda, Sravanthi Avuthu
