Patent number: 11937826Abstract: Various systems and methods of deploying an implant to a target location of a body vessel are disclosed. A delivery system can include a delivery tube and a pull tube, the pull tube at least partially disposed within a first lumen of the delivery tube. A link wire with two proximal ends can be welded to the pull tube and a distal end of the link wire can include a link wire loop. A pull wire can extend through the first lumen with a distal end positioned to secure the implant to the delivery system. The pull wire includes a proximal bend positioned around the link wire loop such that the proximal bend is positioned in a proximal direction relative to the distal end of the link wire loop by a slack length. The slack length is effective to prevent premature detachment of the implant from the delivery system.Type: GrantFiled: March 14, 2022Date of Patent: March 26, 2024Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Daniel Solaun, Thomas Gallerani, David Blumenstyk

Patent number: 11937825Abstract: Various systems and methods of delivering an implant to a target location of a body vessel are disclosed. A detachment system can include a tubular body including a lumen extending therethrough and a distal tube on a distal end of the tubular body. A loop wire can be affixed at a first end to the tubular body and can include a loop opening positioned approximate a distal end of the distal tube. A pull wire can extend through the lumen. A hook wire can extend radially through a sidewall of the distal tube and into the lumen. The hook wire can be positioned around a pull wire portion and tensioned such that the pull wire portion abuts the distal tube and provides frictional resistance between the pull wire portion and the sidewall of the distal tube. The frictional resistance can be effective to inhibit premature detachment of the implant.Type: GrantFiled: March 2, 2022Date of Patent: March 26, 2024Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Daniel Solaun, David Blumenstyk

Publication number: 20230233211Abstract: A delivery and detachment system for an implantable intravascular treatment device including a proximal inner tube telescopically receivable and axially slidable in a proximal direction within the lumen of the outer delivery tube. Specifically, the proximal inner tube comprises a proximal section and a distal section having different outer diameters forming a transition, wherein the distal section includes two distal section components connected by an axially separable region. When the axially separable region is axially separated: (i) the proximal section of the proximal inner tube is slidable in a proximal direction through the stopping member until the transition in the outer diameter of the first distal section component attached thereto engages a stopping member prohibiting axial movement in the proximal direction; and (ii) the restricting element maintaining in position the second distal section component within the outer delivery tube.Type: ApplicationFiled: January 24, 2022Publication date: July 27, 2023Inventors: David BLUMENSTYK, Daniel SOLAUN, Joshua LIEBOWITZ

Publication number: 20230200819Abstract: An aneurysm treatment system can include an embolic implant, a delivery system, and a handle member that are collectively designed so that the combination of the handle member and the delivery system can be used as a deployment apparatus for the embolic implant. A proximal extension of the delivery tube can be placed inside a handle channel of handle member and the handle member can be manipulated to cause the proximal extension to bend to a predetermined angle with respect to the delivery tube, thereby separating the proximal extension from the delivery tube at a disconnection feature between the proximal extension and the delivery tube. The delivery tube includes a lumen having a pull wire that runs through the delivery tube and into the proximal extension. The proximal extension, pull wire, and handle member can be translated proximally in relation to the delivery tube to deploy the embolic implant.Type: ApplicationFiled: December 29, 2021Publication date: June 29, 2023Applicant: DePuy Synthes Products, Inc.Inventors: David BLUMENSTYK, Daniel SOLAUN, Masood SIDDIQUI

Publication number: 20230089430Abstract: An intravascular treatment system including an introducer sheath having an intentional friction zone along a section thereof imposing an intentional friction force on the outer surface of a catheter shaft slidable therein. The friction zone representing a non-straight (e.g., curved or bent) section of the introducer sheath and/or a section of the introducer sheath whose inner wall has a reduced inner diameter (e.g., fused heat shrink material). During intravascular treatment, sufficient axial force may be applied to overcome the imposed intentional friction force and advance the intravascular treatment device in a distal direction to a desired target site in the artery. Once properly positioned, the imposed intentional friction force ensures that the intravascular treatment device is maintained in place.Type: ApplicationFiled: September 22, 2021Publication date: March 23, 2023Inventors: Daniel SOLAUN, David BLUMENSTYK, Chelsea DAHLINE
