Mark Leung - Duncan CA, US

International Classification:

A61B 18/14
A61B 18/18
A61B 34/20

Abstract:

A system for treatment of a target region of lung tissue including: a flow regulator configured to be interposed between a conductive fluid source and a conductive fluid outlet positionable at or in proximity of the target region of lung tissue, the flow regulator being further configured for controlling a flow rate or a bolus quantity of conductive fluid coming from the fluid source and delivered to the conductive fluid outlet; and a controller communicatively connectable with said flow regulator and with at least one sensor, with the at least one sensor being configured for detecting values taken by at least one control parameter representative of a physical property, wherein the physical property is one of temperature (T), pressure (p), electric impedance (Z), or electric conductivity (C) of material present at or in proximity of the target region of lung tissue.

International Classification:

A61B 18/14
A61B 34/20

Abstract:

An ablation catheter configured to ablate tissue in a lung of a patient including: a flexible shaft that advances endobronchially into an airway of the lung and has an outer diameter of 2.0 mm or less; an ablation electrode attached to a distal portion of the flexible shaft and to deliver radiofrequency (RF) electrical current to the tissue and conductively connectable to an RF electrical energy source external to the patient; wherein an outer diameter of an assembly of the flexible shaft and the ablation electrode is no greater than 2.0 mm; a liquid outlet on the distal portion and configured to be in fluid communication with a source of hypertonic saline solution; and a first occluder attached to the flexible shaft proximal to the ablation electrode and proximal to the liquid outlet, wherein the first occluder is configured to expand to occlude the airway.

International Classification:

A61M 25/10

Abstract:

A medical device includes a catheter, an expandable balloon on the distal portion of the catheter, and a sheath that is configured to enclose and protect the expandable balloon. The sheath extends within a sheath lumen of the catheter and out from the catheter through a distal opening of the sheath lumen. When in a deployed configuration, the sheath extends proximally to enclose at least a portion of the expandable balloon. The sheath may be axially movable within the sheath lumen of the catheter to actuate from the deployed configuration to a retracted configuration. In moving to the retracted configuration, the sheath may expose the outer surface of the expandable balloon.
