Patent number: 11925332Abstract: Certain aspects relate to percutaneous sheaths for medical procedures as well as to related systems and methods. For example, a system for performing a percutaneous assisted medical procedure can include a percutaneous sheath. The percutaneous sheath can include a first conduit for providing aspiration into the kidney and a second conduit for passing a catheter into the kidney. The system can also include an aspiration catheter configured to be inserted into the kidney through the second conduit of the percutaneous sheath. A fluidics system can include an irrigation source comprising a pump and an aspiration source comprising a vacuum. The irrigation source can be connected to a fluid inlet of the percutaneous sheath that is connected to the first conduit. The aspiration source can be connected to the aspiration catheter.Type: GrantFiled: December 27, 2019Date of Patent: March 12, 2024Assignee: Auris Health, Inc.Inventors: Polly Charlene Ma, Binh T. Nguyen, Ka Chun Wong, Ryan Jeffrey Connolly, Javier O. Fajardo Vargas, Umberto Scarfogliero, Zachary Stahl Morrison

Patent number: 11717147Abstract: Certain aspects relate to systems and techniques for an endoscopic system to access, visualize, and treat pathologies in various organs via natural orifices and lumens of various organs. In one aspect, the system includes an elongate shaft configured for insertion into a urinary tract of a patient. The elongate shaft can include a proximal section, a distal section, a tip portion, and a plurality of pull wires extending along the elongate shaft and terminating at the tip portion of the elongate shaft. The plurality of pull wires may include a first and second pull wire. The first pull wire may be configured to articulate each of the proximal section and the distal section in a first direction.
