Delivery methods and devices for implantable bronchial isolation devices
First Claim
1. A device for sizing an inside diameter of a lung passageway and delivering a bronchial isolation device into the passageway, the device comprising:
- an elongate shaft configured for positioning in the lung passageway;
a housing located at or near a distal end of the elongate shaft for housing the bronchial isolation device; and
a sizing element disposed along the elongate shaft at or near the housing, the sizing element comprising a plurality of transverse extensions, wherein each extension has a fixed length, and wherein said plurality of extensions comprises;
two long transverse extensions disposed approximately opposite one another across the shaft, wherein a first length from a tip of one long extension to a tip of the other long extension corresponds to a maximum diameter of the lung passageway in which the bronchial isolation device may be functionally delivered; and
two short transverse extensions disposed approximately opposite one another across the shaft, wherein a second length from a tip of one short extension to a tip of the other short extension corresponds to a minimum diameter of the lung passageway in which the bronchial isolation device may be functionally delivered.

Abstract
Disclosed is a sizing device for sizing an inside diameter of a lung passageway. The device includes an elongate shaft configured for positioning in the lung passageway and a sizing element at the distal end of the shaft. The sizing element defines a range of transverse dimensions that correspond to a range of transverse dimensions suitable for use with a predetermined set of bronchial isolation devices. The device is used to determine the suitability of a bronchial isolation device for use in the lung passageway prior to using a separate delivery catheter to deliver the bronchial isolation device into the lung passageway.

7. A device for sizing an inside diameter of a lung passageway and delivering a bronchial isolation device into the passageway, the device comprising:
-
an elongate shaft configured to be entered into the lung passageway via a bronchoscope; a housing located at or near a distal end of the elongate shaft for housing the bronchial isolation device; and a sizing element disposed at or near the distal end of the shaft, the sizing element comprising a plurality of transverse extensions, wherein each extension has a fixed length and provides an indication as to the size of the lung passageway to allow a user to determine whether the passageway has a diameter suitable for delivery of the bronchial isolation device. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
