Abstract
A method and system for instilling a medium into portions of a luminal network is provided. The method includes generating a model of a luminal network based on images of the luminal network, determining a location of a treatment target in the luminal network, navigating a bronchoscope through the bronchial tree to a target, guiding a catheter through the bronchoscope, dispensing medium to the target from a distal end of the catheter, and removing a quantity of medium from the luminal network.
Claims17
A method of instilling a therapy medium into portions of a luminal network comprising:
- generating a model of a luminal network based on images of the luminal network;
- determining a location of a target in the luminal network;
- guiding a catheter to the target, the catheter including a medium channel and at least one medium outlet in fluid communication with the medium channel for delivering a therapy medium to the target;
- isolating an area of the luminal network around the target by inflating a first balloon coupled to the catheter and inflating a second balloon coupled to the catheter distal to the first balloon such that the isolated area is disposed between the first and second inflated balloons;
- passing air through a bypass channel of the catheter, the bypass channel extending distal to the isolated area and extending through the catheter distally beyond a distal end of the medium channel, wherein a distal-most end of the catheter forms a distal opening of the bypass channel through which the air exits the bypass channel for delivery into the luminal network distal to the isolated area of the luminal network;
- dispensing, via the at least one medium outlet, the therapy medium within the isolated area of the luminal network to the target;
- removing a volume of the therapy medium from the isolated area of the luminal network;
- measuring the volume of therapy medium removed from the isolated area of the luminal network;
- and
- determining whether the volume of the therapy medium removed from the isolated areas of the luminal network equals or exceeds a threshold volume based on a volume of the therapy medium dispensed to the isolated area of the luminal network.

A method of instilling a therapy medium into portions of a luminal network comprising:
- guiding a catheter to a target within the luminal network, the catheter including a medium channel and at least one medium outlet in fluid communication with the medium channel for delivering a therapy medium to the target;
- isolating an area of the luminal network around the target by inflating a first balloon and a second balloon coupled to a distal portion of the catheter until the first balloon contacts walls of the luminal network and the second balloon contacts walls of the luminal network creating a seal between the first balloon and the second balloon;
- passing air through a bypass channel of the catheter, the bypass channel extending distal to the isolated area and extending through the catheter distally beyond a distal end of the medium channel, wherein a distal-most end of the catheter forms a distal opening of the bypass channel through which the air exits the bypass channel for delivery into the luminal network distal to the isolated area;
- dispensing, via the at least one medium outlet, the therapy medium within the isolated area of the luminal network to the target;
- removing a volume of the therapy medium from the isolated area of the luminal network;
- measuring the volume of therapy medium removed from the isolated area of the luminal network;
- and
- determining whether the volume of the therapy medium removed from the luminal network equals or exceeds a threshold volume based on a volume of the dispensed therapy medium.
