Patent number: 11116392Abstract: Devices and methods for locating sinus ostia and positioning a guide wire within the sinus ostia. The subject devices include a shaft having a distal end, a proximal end, a curved region located between the distal and proximal ends, and an interior channel, an extensible and retractable guide wire movably mounted within the interior channel and a probe tip joined to the guide wire. Certain devices further include expandable portions for engaging and treating body anatomy.Type: GrantFiled: December 5, 2018Date of Patent: September 14, 2021Assignee: Acclarent, Inc.Inventors: John H. Morriss, Joshua Makower, Carlos F. Fernandez, Eric Goldfarb, Thomas R. Jenkins

Patent number: 10987497Abstract: A dilation apparatus includes a shaft, a dilation balloon, and a standoff member. The shaft includes a first lumen and a second lumen. The distal end of the second lumen is proximal to the distal end of the first lumen. The dilation balloon encompasses the second distal end of the second lumen such that the dilation balloon defines an interior in fluid communication with the second lumen. A distal portion of the standoff member is positioned within the interior of the dilation balloon. The distal portion of the standoff member is distal to the second distal end of the second lumen. The standoff member provides a pathway for fluid communication between the interior of the dilation balloon and the second lumen. The standoff member may include a tube, a thread, polymeric beading, or other structures.Type: GrantFiled: May 4, 2018Date of Patent: April 27, 2021Assignee: Acclarent, Inc.Inventors: Carlos F. Fernandez, George L. Matlock, Gregory T. Douglass

Patent number: 10034682Abstract: Devices, systems and methods wherein a dilator, such as a balloon or other expandable member, is positionable within the frontal sinus ostium and adjacent frontal recess and useable to dilate the frontal sinus ostium and substantially all of the frontal sinus recess without requiring repositioning and repeated re-expansion of the dilator. One balloon catheter device of the invention comprises a catheter body that is less than about 50 cm in length (and in some embodiments less than 25 cm in length and a semi-compliant or non-compliant balloon on the catheter body. The balloon may have a working length of about 12 mm to about 30 mm and a width at its widest point when fully inflated of about 2 mm to about 7 mm. Such balloon may be constructed to withstand inflation pressures of about 12 atmospheres. In some embodiments, the dilator is advanced through or over a guide (e.g., guidewire or guide catheter) that has a preformed shape.Type: GrantFiled: March 22, 2017Date of Patent: July 31, 2018Assignee: Acclarent, Inc.Inventors: Ketan P. Muni, Carlos F. Fernandez, Joshua Makower, John Y. Chang, William M. Facteau
