| 20090151719 | METHODS AND DEVICES FOR TREATING SLEEP APNEA - A ventilation apparatus for treating sleep apnea is provided. A ventilator controlled by a control system may deliver ventilation gas through a ventilation gas delivery circuit to a ventilation catheter and a distal tip on the ventilation catheter. One or more sensors may detect a breathing cycle and the control system may operate the ventilator in synchrony with the breathing cycle. The distal tip may deliver the ventilation gas superiorly from the transtracheal ventilation catheter towards an upper airway, inferiorly from the transtracheal ventilation catheter towards a lung, or a combination of both. The ventilation catheter may be a transtracheal catheter, a trans-oral catheter or a trans-nasal catheter. | 06-18-2009 |
| 20090151724 | METHODS AND DEVICES FOR PROVIDING INSPIRATORY AND EXPIRATORY FLOW RELIEF DURING VENTILATION THERAPY - Respiratory support and/or controlled mechanical ventilation of a patient are provided. A ventilation apparatus may include a ventilator, a transtracheal prosthesis, and a respiratory relief device. The transtracheal prostheses and ventilation catheter may be arranged such that the patient can breathe freely through the upper airway and/or the tracheal prostheses. Respiratory sensors may measure a breathing rate, lung pressure, airway pressure, or a combination thereof. Pulses of gas may be provided to the patient through the ventilation catheter during inspiration. The pulses may have a first volume while the patient breathes normal and a second volume when the sensors detect a cessation of breathing or reduction in breathing volume. The second volume may be provided at 1-5 times the normal breathing rate, with a volume 25-500% times the first volume, or both. | 06-18-2009 |
| 20090156953 | Methods and devices for sensing respiration and providing ventilation therapy - Methods and systems are provided for intra-airway breath sensors where intra-airway breath sensors are not located within a ventilation gas delivery circuit, but are exposed to spontaneous respiration airflow from a patient. Furthermore, methods and systems of the present invention may be used to protect an intra-airway breath sensor from contacting tissue or accumulating debris that may impair abilities of the intra-airway breath sensors. | 06-18-2009 |
| 20090255533 | SYSTEMS, METHODS AND APPARATUS FOR RESPIRATORY SUPPORT OF A PATIENT - 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. | 10-15-2009 |
| 20100043786 | TRACHEOSTOMA SPACER, TRACHEOTOMY METHOD, AND DEVICE FOR INSERTING A TRACHEOSTOMA SPACER - 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. | 02-25-2010 |
| 20100175693 | PULMONARY OCCLUSAL STENT DELIVERY CATHETER, LOADING SYSTEM AND METHODS OF USE - Methods, systems and devices are provided for performing lung volume reduction in patients suffering from chronic obstructive pulmonary disease or other conditions where isolation of a lung segment or reduction of lung volume is desired. The methods are minimally invasive with instruments being introduced through the mouth (endotracheally) and rely on isolating the target lung tissue segment from other regions of the lung and occluding various lung passageways with the use of occlusal stents. The occlusal stents are delivered with the use of an occlusal stent delivery system which is loaded with the occlusal stent with the use of an occlusal stent loading system. | 07-15-2010 |
| 20110087122 | MINIMALLY INVASIVE DETERMINATION OF COLLATERAL VENTILATION IN LUNGS - Minimally invasive methods, systems and devices are provided for qualitatively and quantitatively 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 bronchus of the target compartment. The feeding bronchus is occluded by the catheter and a variety of measurements are taken with the use of the catheter in a manner which is of low risk to the patient. Examples of such measurements include but are not limited to flow rate, volume and pressure. These measurements are used to determine the presence of collateral ventilation and to quantify such collateral ventilation. | 04-14-2011 |
