Abstract:
Devices to improve lung function in a patient having restricted ventilation. The device may include an entry or access port for an implantable airway bypass device that relieves trapped air. The device of the present invention comprises an expandable structure (164) to be implanted in lung tissue and defining an air capture chamber, a first conduit (174) having a first end from which extends the expandable structure, and a second end to be coupled to a first end of a second conduit (161), the second end of the second conduit being joined to an external anchor (175) to rest against an outer skin surface of the chest of the patient.
Abstract:
Methods and devices to improve lung function in a patient having restricted ventilation from chest hyperinflation and related pulmonary conditions. A bronchoscopically delivered implantable airway bypass device may relieve trapped air. The minimally invasive methods may include procedures that reduce the time required by the overall healing process.
Abstract:
Implantable airway bypass device 150 that relieves trapped air in the lung of a patient having restricted ventilation. The device comprises a conduit that approximately spans the distance of the chest wall, an air intake component (i.e. an open end of a conduit), and a surrounding expandable structure, which further comprises a basket (160) and a neck to surround the air intake component within a voided space in lung tissue, created, and defined by the expandable structure. The expandable structure may bey formed of at least one wire which forms the neck and the basket. The device may further comprise a membrane over at least a portion of an outer surface of the basket and an outer surface of the neck portion.
