Publication number: 20190254850Abstract: Systems and methods for stent deployment are provided. One system includes a delivery subsystem having a nose tip coupled with a sheath such that the nose tip and sheath are movable together, wherein the sheath is configured to receive therein a stent for deployment. The stent surrounds an inner shaft of the delivery subsystem. The system further includes an actuating subsystem configured to advance the sheath along the inner shaft from a proximal to distal direction to deliver the stent in a reverse deploy direction.Type: ApplicationFiled: April 29, 2019Publication date: August 22, 2019Applicant: VENITI, INC.Inventors: PETER NEGLEN, STEPHEN KAO, ABHA CHINUBHAI, DANIEL LAGOE, LIEU TRAN

Publication number: 20170281379Abstract: A mechanical assisted delivery system and method are provided. One mechanical assisted delivery system includes an outer screw housing, a screw configured to rotate within the outer screw housing, an engagement mechanism configured for selective engagement with the screw, an outer shaft coupled to an end of the outer screw housing, a midshaft extending through the screw and a hub coupled to an end of the midshaft.Type: ApplicationFiled: March 29, 2017Publication date: October 5, 2017Applicant: VENITI, INC.Inventors: Dan LAGOE, Stephen KAO, Abha CHINUBHAI, Daniel RECINELLA, Jeff ELKINS, Trudy NGUYEN

Patent number: 9314360Abstract: A bi-directional stent delivery system includes an inner elongate shaft, a radially expandable prosthesis disposed over the inner elongate shaft, an outer elongate shaft, and a shuttle sheath disposed over the radially expandable prosthesis. The distal portion of the inner shaft is releasably coupled to the distal portion of the shuttle sheath, and the distal portion of the outer shaft is releasably coupled the proximal portion of the shuttle sheath. Distal advancement of the inner shaft advances the shuttle sheath distally when the outer shaft is uncoupled from the shuttle sheath, thereby allowing the prosthesis to radially expand from a proximal end to a distal end. Proximal retraction of the outer shaft retracts the shuttle sheath proximally when the inner shaft is uncoupled from the shuttle sheath, thereby allowing the prosthesis to radially expand from a distal end to a proximal end thereof.Type: GrantFiled: September 16, 2014Date of Patent: April 19, 2016Assignee: Veniti, Inc.Inventor: Stephen Kao

Patent number: 9233014Abstract: A stent includes expandable rings formed from a plurality of interconnected struts. A plurality of bridges couple adjacent rings together. The bridges are connected to adjacent rings at first and second connection points, and a first brace element is disposed therebetween. The first connection point is circumferentially offset relative to the second connection point so that the bridge is transverse to the longitudinal axis of the stent. The first brace element of one bridge engages an adjacent bridge or a brace element of the adjacent bridge when the corresponding adjacent rings are in the contracted configuration thereby providing additional support and rigidity to the stent to lessen buckling of the stent during loading onto a delivery catheter or during deployment therefrom.Type: GrantFiled: November 18, 2010Date of Patent: January 12, 2016Assignee: VENITI, INC.Inventor: Stephen Kao

Publication number: 20140207054Abstract: A method of delivering therapy to a treatment volume of a vein of a patient includes inserting a vapor delivery shaft into the vein at an entry location. The vein is fluidly coupled with other veins in a venous vasculature of the patient. The method also includes applying a compressive force to tissue surrounding the venous vasculature to compress and at least partially occlude the venous vasculature at an occlusion location other than the entry location. A treatment volume is formed between the entry location and the occlusion location. The method further includes delivering vapor to the vein through the vapor delivery shaft into the treatment volume.Type: ApplicationFiled: January 22, 2014Publication date: July 24, 2014Applicant: Veniti, Inc.Inventors: Lowell S. Kabnick, Daniel Recinella, Kimberly McCarthy
