Publication number: 20250186736Abstract: A rapid exchange microcatheter for accessing the intracranial neurovasculature. A side opening through the sidewall is located a first distance proximal to the distal-most tip. A proximal opening located proximal to the side opening is a second distance from the distal-most tip. A distal, reinforced catheter portion extends between a distal end region to a point near the side opening. A proximal, reinforced catheter portion extends a distance from a point near the side opening towards the proximal end of the catheter body. The side opening is positioned within a gap between a proximal end of the distal reinforced catheter portion and a distal end of the proximal reinforced catheter portion. A payload of a cerebral treatment device is housed within the lumen proximal to the side opening. Related devices, systems, and methods are disclosed.Type: ApplicationFiled: December 13, 2024Publication date: June 12, 2025Inventors: Tony M. Chou, Scott D.

Patent number: 12295595Abstract: Described are methods, systems, devices for facilitation of intraluminal medical procedures within the neurovasculature. A catheter advancement device includes a flexible elongate body having a proximal portion coupled to a proximal end region of the flexible elongate body and extending proximally to a proximal-most end of the catheter advancement element. A hardness of the flexible elongate body transitions proximally towards increasingly harder materials up to the proximal portion forming a first plurality of material transitions. At least a portion of the flexible elongate body is formed of a plurality of layers including a reinforcement layer. An outer diameter of the flexible elongate body is sized to be positioned coaxially within a lumen of a catheter such that a distal tip portion of the flexible elongate body extends distally beyond a distal end of the catheter to aid in delivery of the catheter to an intracranial vessel.Type: GrantFiled: May 13, 2021Date of Patent: May 13, 2025Assignee: Route 92 Medical, Inc.Inventors: Scott D.

Patent number: 8951225Abstract: Balloon catheter, guide catheter and method for dilating openings in paranasal sinuses. A non-removable guide member (e.g., guidewire) extends from the distal end of the balloon catheter. The non-removable guide member initially passes through the opening of the paranasal sinus and is followed by the catheter body on which the balloon is mounted. The balloon is then inflated causing dilation of the opening of the paranasal sinus. In some embodiments, the non-removable guide member may be shapeable so that the operator may place the non-removable guide member in a desired shape prior to insertion of the balloon catheter. In some embodiments, the length of the non-removable guide member may be adjustable such that the operator may adjust the length of the non-removable guide member prior to insertion of the balloon catheter.Type: GrantFiled: May 18, 2006Date of Patent: February 10, 2015Assignee: Acclarent, Inc.Inventors: Philip Evard, Ketan P.
