Patent number: 11523831Abstract: Intrasaccular flow diverter including: an interior fill braid physically inverted over itself forming a proximal inverted end and an opposite free end; and a dome braid disposed distally of and secured to the interior fill braid. Subject to application of an external mechanical force, the dome braid is transitionable between an expanded state and a compressed state. The dome braid has a proximal end with an opening defined therein through which starting at the free end the interior fill braid is passable therethrough exerting a radially outward force on the dome braid. A delivery wire is releasably detachable from the proximal inverted end of the interior fill braid. The dome braid has a stiffer profile relative to that of the interior fill braid to maintain in position within the aneurysm the dome braid as the interior fill braid is advanced therein.Type: GrantFiled: April 30, 2020Date of Patent: December 13, 2022Assignee: DePuy Synthes Products, Inc.Inventors: Lacey Gorochow, Ariel Soto Del Valle, Juan Lorenzo

Publication number: 20220361893Abstract: An example system for deploying an intrasaccular implant to occlude an aneurysm can include the intrasaccular implant with a securing ring thereon, a pusher, a securing wire with an extended securing feature thereon, and a pull wire. The system can be sized to be delivered intravascularly within a microcatheter. During delivery and manipulation of the implant, the securing ring can be held between the pusher and the securing feature of the securing wire with the securing wire and pull wire extended through securing ring. To deploy the implant, the pull wire can be retracted proximally to thereby allow the securing feature to pass through the securing ring and release the implant. The pusher can include a hypotube and/or an extended pushing feature on the securing wire.Type: ApplicationFiled: August 1, 2022Publication date: November 17, 2022Applicant: DePuy Synthes Products, Inc.Inventors: Ariel SOTO DEL VALLE, Juan LORENZO, Lacey GOROCHOW

Publication number: 20220117606Abstract: An assembly at a proximal end of an intravascular delivery system can allow the proximal end of a pull wire to move independently of a delivery tube. The assembly can generally include the pull wire, the delivery tube, a feature to prevent the proximal end of the pull wire from becoming inaccessible due to distal movement of the pull wire, and a feature to protect the proximal end of the pull wire from inadvertent, premature manipulation. When the intravascular delivery system is navigating tortuous vasculature, the proximal end of the pull wire can move distally in relation to the proximal end of delivery tube, relieving stress on the distal end of the pull wire. The proximal end of the pull wire can be protected from inadvertent manipulation during delivery and made available for manipulation once the distal end of the delivery system is in place.Type: ApplicationFiled: December 29, 2021Publication date: April 21, 2022Applicant: DePuy Synthes Products, Inc.Inventors: Tyson MONTIDORO, Juan LORENZO

Publication number: 20220061863Abstract: The disclosed technology includes a balloon guide catheter having a substantially tubular body, an inflation lumen, and a balloon. The tubular body can include an inner hollow lumen and a distal end. The inflation lumen can have a distal end and a proximal section. The distal end of the inflation lumen can be in connection with the tubular body approximate to the distal end of the tubular body. The proximal section of the inflation lumen can extend a majority of the length of the tubular body and can be moveable in relation to the tubular body. The inflation lumen can be positioned within an inner hollow lumen of a tubular body of the catheter or external to the tubular body, thereby enhancing flexibility of the catheter.Type: ApplicationFiled: August 28, 2020Publication date: March 3, 2022Applicant: DePuy Synthes Products, Inc.Inventors: Juan LORENZO, Kirk JOHNSON

Publication number: 20220054136Abstract: A method of constructing a detachment system for delivering an implantable medical device to a target location of a body vessel is presented. The method includes forming a compressible portion on a distal tube, engaging an implantable medical device with an engagement system, extending the engagement system through the distal tube such that the implantable medical device is distal of a distal end of the distal tube, applying a force to the engagement system to compress the compressible portion to a compressed state, fixing the engagement system to the distal tube to maintain the compressed state of the compressible portion, and joining a proximal end of the distal tube to a distal end of a proximal tube. The engagement system can include a loop wire that is fixed to the distal tube and engages the medical device.Type: ApplicationFiled: September 9, 2021Publication date: February 24, 2022Applicant: DePuy Synthes Products, Inc.Inventors: David BLUMENSTYK, Ariel SOTO DEL VALLE, Daniel SOLAUN, Juan LORENZO

Publication number: 20210401439Abstract: Implant deployment systems can generally include a braided implant that can be detachably attached to a delivery tube by an expansion ring that can be positioned within a notch on an outer surface of the delivery tube near a distal end of the delivery tube. The implant can be positioned within a lumen of the delivery tube and remain attached to the delivery tube as the assembly is fed through a microcatheter to a treatment site. Once the braided implant is implanted, the expansion ring can move from a collapsed configuration that is engaged with the notch of the delivery tube to a deployed configuration that releases the delivery tube, thereby releasing the braided implant from the delivery tube.Type: ApplicationFiled: September 9, 2021Publication date: December 30, 2021Applicant: DePuy Synthes Products, Inc.Inventors: Juan LORENZO, Kirk JOHNSON, Lacey GOROCHOW
