Patent number: 11944717Abstract: Disclosed are methods, devices and materials for the in situ formation of a nerve cap and/or a nerve wrap to inhibit neuroma formation following planned or traumatic nerve injury. The method includes the steps of identifying a severed end of a nerve, and positioning the severed end into a cavity defined by a form. A transformable media is introduced into the form cavity to surround the severed end. The media is permitted to undergo a transformation from a first, relatively flowable state to a second, relatively non flowable state to form a protective barrier surrounding the severed end. The media may be a hydrogel, and the transformation may produce a synthetic crosslinked hydrogel protective barrier. The media may include at least one anti-regeneration agent to inhibit nerve regrowth.Type: GrantFiled: September 17, 2021Date of Patent: April 2, 2024Assignees: Tulavi Therapeutics, Inc., Incept, LLCInventors: Corinne Bright, Yong Ren, Kenneth M. Martin, Farhad Khosravi, Amarpreet S. Sawhney

Patent number: 11510797Abstract: Apparatus and methods are provided for flaring a stent deployed within a branch vessel including an ostium communicating with a main vessel, a first end of the stent extending at least partially from the branch. A catheter is provided that includes a balloon having a reinforced region adjacent an unreinforced region. When the balloon is positioned at a desired location, e.g., within a stent, prosthetic valve, or other tubular prosthesis, the balloon may be inflated to a first pressure causing the reinforced and unreinforced regions to expand substantially simultaneously. Upon inflation of the balloon beyond the first pressure, the reinforced region of the balloon remains at the first diameter and the unreinforced region continues to expand, e.g., to flare one or more ends of the prosthesis.Type: GrantFiled: November 11, 2019Date of Patent: November 29, 2022Assignee: OSTIAL CORPORATIONInventors: Yi Yang, Jake Wolenberg, Archimedes Sanati, Fred H.

Patent number: 11311303Abstract: A neurovascular catheter having an angled distal tip has an elongate flexible tubular body with a proximal end, a distal end and a side wall defining a central lumen. The side wall has a helical coil. A tubular jacket surrounds the helical coil, and extending distally beyond the helical coil distal end to terminate in a catheter distal face. A tubular radiopaque marker is embedded in the tubular jacket in between the distal end of the coil and the distal face. The distal face resides on a plane which crosses a longitudinal axis of the tubular body at an angle within the range of from about 35 degrees to about 55 degrees. The marker has a proximal face that is approximately perpendicular to the longitudinal axis and a distal face that resides on a plane which crosses the longitudinal axis at an angle within the range of from about 35 degrees to about 55 degrees.Type: GrantFiled: September 13, 2019Date of Patent: April 26, 2022Assignee: Incept, LLCInventors: Yi Yang, Farhad Khosravi, Lisa M.
