BRONCHIAL SEALANT DELIVERY METHODS AND SYSTEMS

摘要

Devices, methods, and systems are provided for sealing a lung region. The target lung compartment is accessed and isolated via an isolation catheter. Fluid is delivered into the target lung compartment such that the target compartment is pressurized and the fluid flows through the collateral flow channel. A sealing agent is injected into the isolated lung compartment such that the agent is carried by the fluid to the collateral flow channel, thereby sealing the collateral flow channel. Variables of air flow may be measured or analyzed prior to injection of the sealing agent, or the sealing agent may be introduced into the region after a suitable time has elapsed.

1. A method for occluding a collateral flow channel between a target lung compartment and an adjacent lung compartment, said method comprising:
accessing the target lung compartment through an isolation catheter isolating the target lung compartment; delivering a fluid into the target lung compartment such that the target compartment is pressurized and the fluid flows through the collateral flow channel; and injecting an agent into the isolated lung compartment such that the agent is carried by the fluid to the collateral flow channel, thereby sealing the collateral flow channel.
