RESORBABLE, DRUG-ELUTING SUBMUCOSAL TURBINATE IMPLANT DEVICE AND METHOD |
| 摘要 |
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. |

1. A surgical device comprising:
(a) a proximal grip portion configured to be grasped outside a patient; (b) a distal hollow sharp needle portion configured to be manipulated using the grip portion and inserted submucosally into mucosal turbinate tissue in the patient; (c) one or more biodegradable, drug-eluting solid implants disposed within the hollow needle portion, the implants having a length along the hollow needle portion, and one or more implant withdrawal-discouraging, mucosal tissue-engaging surface features along such length; and (d) an actuator disposed within the device and configured to deliver one or more of the implants from the hollow needle portion into such mucosal turbinate tissue and submucosally bury at least one such tissue-engaging feature therein. |
