Publication number: 20210196284Abstract: A method of occluding an aneurysm includes positioning a braided implant within an aneurysm sack such that an outer non-inverted layer contacts a wall of the aneurysm and an inverted layer apposes the outer non-inverted layer to form a double layer of braid across a neck of the aneurysm. A radiopaque end of the braided implant can be positioned centrally within the aneurysm so that the radiopaque end extends adjacent or across a plane defined by a fold between the outer non-inverted layer and the inner inverted layer. Embolic coils can be inserted into the aneurysm sac and inhibited from exiting the aneurysm at the neck by the double layer braid across the aneurysm neck.Type: ApplicationFiled: March 17, 2021Publication date: July 1, 2021Applicant: DePuy Synthes Products, Inc.Inventors: Lacey GOROCHOW, Juan LORENZO

Publication number: 20210186518Abstract: An example implant can have a tubular braid. The tubular braid can have an intrasaccular section, an intravascular section, a pinched section, and a predetermined shape. In the predetermined shape, the intrasaccular section can have a sack and an opening. The pinched section can be positioned approximate the opening. The intravascular section can be substantially disk shaped and positioned to occlude the opening. The tubular braid can be movable from a collapsed shape sized to traverse a catheter to an implanted shape based at least in part on the predetermined shape. In the implanted shape, the intrasaccular section of the braid can be sized to be positioned within an aneurysm's sac and the intravascular section of the braid can be sized to appose a blood vessel wall approximate an aneurysm's neck.Type: ApplicationFiled: December 18, 2019Publication date: June 24, 2021Applicant: DePuy Synthes Products, Inc.Inventors: Lacey GOROCHOW, Ruijiao XU, Yusuf SEVENCAN

Publication number: 20210169498Abstract: A method for constructing a braided implant delivery system and treating an aneurysm can include attaching a braided implant having a band attached thereto to a delivery tube, positioning the braided implant within the aneurysm, and releasing the band from the delivery tube, thereby releasing the braided implant. The band can include movable extensions that can press into an outer surface of the delivery tube to secure the band to the delivery tube then move away from the outer surface of the delivery tube to release the band. A pull wire can be engaged to the band to secure the band to the delivery tube then be pulled proximally to release the band from the delivery tube. At least a portion of the braid of the braided implant can be positioned within a lumen of the delivery tube.Type: ApplicationFiled: February 23, 2021Publication date: June 10, 2021Applicant: DePuy Synthes Products, Inc.Inventor: Lacey GOROCHOW

Publication number: 20210169495Abstract: A tubular braided implant is provided including a braid that can be delivered as a single layer braid, invert into itself during deployment to form at least two nested sacks and include additional braid material that can fill the innermost sack. The additional braid material can loop or coil like a ribbon and/or invert to form smaller and smaller nested sacks. The braid can have a variable braid angle along its length such that when positioned for delivery, the can have a high braid angle near its distal end and a low braid angle near the proximal end. In addition, or as a replacement for the braid material that fills the innermost sack, the implant can include an embolic coil that can loop within the innermost sack.Type: ApplicationFiled: December 5, 2019Publication date: June 10, 2021Applicant: DePuy Synthes Products, Inc.Inventors: Lacey GOROCHOW, Juan LORENZO, Ruijiao XU

Publication number: 20210145449Abstract: An implant system presented herein includes an engagement wire, a pull wire, and a braided implant having a distal ring thereon. The engagement wire has an elongated member with a radially extending engagement feature at its distal end. The braid can be moved from a delivery shape sized to traverse a catheter to an implanted shape sized to occlude an aneurysm neck. When the braid is in the delivery shape, the pull wire and the elongated member extend through the distal ring and the engagement feature is in a distal direction in relation to the distal ring. Once at least a portion of the braid is positioned in the aneurysm, the pull wire and the elongated member can be moved in a proximal direction to engage the engagement feature to the distal ring and move the distal ring proximally, thereby reshaping the braid within the aneurysm.Type: ApplicationFiled: November 18, 2019Publication date: May 20, 2021Applicant: DePuy Synthes Products, Inc.Inventor: Lacey GOROCHOW
