Implants are placed in turbinate mucosal tissue using a surgical device having a proximal grip portion and a distal hollow sharp needle portion that is manipulated using the grip portion and inserted submucosally into mucosal turbinate tissue. One or more biodegradable, drug-eluting solid implants are disposed within the needle. The implants have one or more implant withdrawal-discouraging, mucosal tissue-engaging surface features along their length. An actuator disposed within the device is used to deliver one or more of the implants from the needle into the mucosal turbinate tissue and submucosally bury at least one such tissue-engaging feature therein.

An injection needle includes a first needle portion defining a first outer diameter, a second needle portion defining a second outer diameter that is smaller than the first outer diameter, the second needle portion having a tip configured to penetrate a soft tissue. Importantly, the first end of the second needle portion is positioned substantially inside and coupled to an inner surface of the first needle portion adjacent an angled section that is positioned adjacent a distal end of the first needle portion. In addition, the first and second needle portions may be crimped or pinched together into a unitary construction that still allows a pharmaceutical to pass therethrough.

A lavage catheter for the treatment of a maxillary sinus is described. The catheter comprises a proximal portion and a distal portion. The distal portion comprises an irrigation tip. The irrigation tip has a tip opening through which fluid may be delivered by one handed operation of the catheter. A method for lavaging the maxillary sinus includes inserting the lavage catheter into a patient's anatomy and advancing the irrigation tip into the maxillary sinus using one hand.

Described herein are devices and methods for irrigating and suctioning fluids from the lumens or cavities of a mammalian body. The devices include a malleable irrigation tube and a suction tube that is slidably mounted upon the irrigation tube.

A sinuplasty tool, consisting of a handle, and a rigid tube, containing a rigid tube lumen, having a rigid tube distal end and a rigid tube proximal end connected to the handle. The tool also has a resilient tube, containing a resilient tube lumen, having a resilient tube distal end and a resilient tube proximal end fixed to the rigid tube distal end so that the lumens align. The resilient tube has a multiplicity of separated openings partially encircling the resilient tube so as to form ribs in the resilient tube and permitting the resilient tube to bend. The resilient tube distal end may be inserted into a sinus of a living subject. The tool also has a wire, traversing the aligned lumens, connected to the resilient tube distal end and coupled to the handle, so that applying tension to the wire causes the resilient tube to bend.

This disclosure describes, inter alia, materials, devices, kits and methods that may be used to treat chronic sinusitis. More specifically, a drug-eluting scaffold is implanted in the middle meatus to treat chronic sinusitis for weeks to months.

In an example, a bioresorbable implant for use in a nasal region includes one or more bioresorbable polymers, and a pharmaceutical composition coupled to the one or more bioresorbable polymers. A release rate of the pharmaceutical composition is related to a degradation rate of the one or more bioresorbable polymers.
