摘要:
A stent (100) that is sleeved and radially expandable, and which in an expanded state provides a breathable, generally tubular structure sized and shaped for residence in a sinus or nasal cavity or passage, and in an unexpanded state has a cross-sectional diameter suitable for insertion into such cavity or passage. The sleeve limits expansion and outward pressure exerted by the stent and thereby can prevent or reduce the incidence of headache in patients, and can provide increased surface area for improved elution of drugs to nearby mucosal tissue.
摘要:
Implants are placed in turbinate mucosal tissue using a surgical device having a proximal grip portion and a distal 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 or attached to the needle. The implants have one or more implant withdrawal-discouraging, mucosal tissue-engaging surface features along their length. The device is used to deliver one or more of the implants into mucosal turbinate tissue and submucosally bury at least one such tissue-engaging feature therein.

摘要:
A purified and sterilized polysaccharide that exhibits enhanced and extended shelf life over conventionally prepared polysaccharides for biomedical applications. The polysaccharide, upon crosslinking, forms a hydrogel that functions as a protective coating or on tissue and structures in the ears, nose, throat, limbs and spinal column.
