US Patent:

20230105224, Apr 6, 2023

Filed:

Dec 8, 2022

Appl. No.:

18/078001

Inventors:

- Rancho Santa Margarita CA, US
Nicholas J. Fox - Irvine CA, US
Quoc P. Tran - Rancho Santa Margarita CA, US

International Classification:

A61B 17/221
A61B 17/00

Abstract:

A tissue retrieval system including a tissue retrieval bag deployable by an actuator from an introducer and suspended in an open configuration by support arms can be serially redeployed between a partially or fully stowed configuration and a first deployed configuration to be used in procedures to collect multiple samples. The system can include defeasible proximal and distal stop mechanisms to limit movement of the actuator for serial redeployment. The tissue retrieval system can include a retention latch to couple a bead of the tissue retrieval bag to the actuator with the retrieval bag in the first deployed position and a user-selectable deployment release to allow deployment of the retrieval bag to a fully deployed position where it is released from the actuator. A bead stop is positioned to engage the introducer to prevent reintroduction of the bead and bag into the introducer once the bag has been fully deployed.
