Patent number: 8985099Abstract: The invention relates to a tracheostoma spacer with a tubular support framework. The support framework can be expand from an initial state to a supporting state of increased diameter and has a fixing element at the ends. The tracheostoma spacer is intended for use as a spacer in a tracheostoma (an opening in the trachea). The invention further relates to a device for inserting a tracheostoma spacer into a tracheostoma with a cutting instrument in the form of a trocar, the tracheostoma spacer being able to be positioned on the shaft of said trocar. A cover sleeve is also provided which can be moved on the shaft over a tracheostoma spacer positioned there.Type: GrantFiled: February 17, 2012Date of Patent: March 24, 2015Assignee: Breathe Technologies, Inc.Inventors: Lutz Freitag, Anthony D.

Publication number: 20140142455Abstract: Minimally invasive methods, systems and devices are provided for assessing collateral ventilation in the lungs. In particular, collateral ventilation of a target compartment within a lung of a patient is assessed by advancement of a catheter through the tracheobronchial tree to a feeding airway of the target compartment. The feeding airway is occluded by the catheter and the opening and closing of a one-way valve coupled with the catheter is observed. If the valve ceases opening and closing over time, this may indicate that significant collateral ventilation into the target compartment is absent. If the valve continues to open and close over time, significant collateral ventilation into the compartment may be present. Based on the collateral ventilation assessment, a treatment plan may be generated.Type: ApplicationFiled: April 19, 2013Publication date: May 22, 2014Applicant: Pulmonx CorporationInventors: Lutz Freitag, Nikolai Aljuri

Patent number: 8677999Abstract: Methods, systems and devices are described for providing mechanical ventilation support of a patient using an open airway patient interface. The system includes gas delivery circuit and patient interface configurations to optimize performance and efficiency of the ventilation system. A ventilation system may include a ventilator for supplying ventilation gas. A patient interface may include distal end in communication with a patient airway, a proximal end in communication with ambient air, and an airflow channel between the distal end and the proximal end. A gas delivery circuit may be adapted to attach to the patient interface without occluding the patient interface to allow ambient air to flow from outside the patient interface to the patient airway. The ventilation gas may entrain air from ambient and from the patient airway.Type: GrantFiled: August 21, 2009Date of Patent: March 25, 2014Assignee: Breathe Technologies, Inc.Inventors: Todd A. Allum, Anthony D. Wondka, Joseph Cipollone, Lutz Freitag

Patent number: 8631797Abstract: Spontaneous respiration is detected by sensors. An additional amount of oxygen is administered to the lungs via a jet gas current at the end of an inhalation procedure. Breathing volume, absorption of oxygen during inhalation, and clearance of carbon dioxide during exhalation are improved. If required, the exhalation procedure of the patient can be arrested or slowed by a countercurrent to avoid a collapse of the respiration paths. An apparatus including an oxygen pump can be connected to an oxygen source and includes a tracheal prosthesis that can be connected via a catheter. The respiration detections sensors are connected to a control unit for activating the oxygen pump. The tracheal prosthesis includes a tubular support body with a connection for the catheter, and the sensors are associated with the support body. The tracheal prosthesis and jet catheter are dimensioned so the patient can freely breathe and speak without restriction.Type: GrantFiled: April 14, 2009Date of Patent: January 21, 2014Assignee: Breathe Technologies, Inc.Inventors: Lutz Freitag, Gregory Kapust, Anthony D.
