Patent number: 9700326Abstract: Shapeable guide catheters and methods for manufacturing and using such shapeable guide catheters. In one embodiment, the shapeable guide catheter comprises a tubular member having a shapeable region, a malleable shaping member attached to the shapeable region such that, when the shape of the shapeable region is changed from a first shape to a second shape, the shaping member will plastically deform to thereafter substantially hold the shapeable region in the second shape, a tubular outer jacket disposed about the outer surface of the tubular member and a tubular inner jacket disposed within the lumen of the tubular member. The shapeable region of the guide catheter may be manually formed into a desired shape before insertion of the guide catheter into the body. In some embodiments, the guide catheter is sized to be inserted through a nostril of a human patient and used to guide the transnasal insertion of another device (e.g., a guidewire, catheter, etc.Type: GrantFiled: April 30, 2014Date of Patent: July 11, 2017Assignee: Acclarent, Inc.Inventors: John H.

Methods, devices and systems for treatment and/or diagnosis of disorders of the ear, nose and throat
Publication number: 20080183128Abstract: A method for irrigating a paranasal sinus may involve advancing a distal portion of a sinus irrigation catheter through an ostium of a paranasal sinus into the sinus and passing fluid through multiple ports disposed at different locations along a length of the catheter distal portion into the sinus. A flexible irrigation catheter device for irrigating a paranasal sinus may include: an elongate catheter body having a proximal end, a distal end, a lumen therebetween, and a tapered distal portion extending proximally from the distal end of the catheter body; a proximal hub coupled with the proximal end of the catheter body for connecting to a source of irrigation fluid; multiple side ports disposed along the catheter body closer to the distal end than the proximal end and in fluid communication with the lumen; and a distal end port at the distal end of the catheter body.Type: ApplicationFiled: January 23, 2008Publication date: July 31, 2008Inventors: John Morriss, Mei Pader, Joshua Makower
