In addition, forces resulting from airway irritation may result in expulsion or displacement of the airway
As these patients are dependent on mechanical ventilation, expulsion and displacement of the airway can lead to significant morbidity

Embodiment Construction

[0045] The present invention is primarily intended to provide tracheal access to a patient for ventilation, drug delivery, and other therapeutic purposes. To this end, the present invention relies on an access device that is anchored within a surgical hole formed in the trachea to provide an access channel; and the invention relies on a ventilation device that can be passed through the access channel to allow Expand with removal. Although described below for use in tracheal access procedures, the access device of the present invention can also be used to access other body cavities and cavities, such as the gastric cavity, intestinal cavity, abdominal cavity, etc., and can be used Used to perform procedures such as laparoscopy, gastroscopy, feeding tube placement, colostomy, ileostomy and more.

[0046] Referring now to FIG. 1, the neck region N of a patient P includes an esophagus E for passing food and drink into the stomach and a trachea T ​​for exchanging air with the lung...

Abstract

A tracheostomy is performed using an access device and a separate ventilation device. The access device is introduced through a surgical opening in the tracheal wall and has an anchor which is expanded in situ to hold the access device in place. The ventilation device is introduced through a passage in the access device and has an expandable cuff which is oriented above the access point through the tracheal wall. A concavity in the expandable cuff collects body secretions, and other materials from the oral and nasal cavities and / or gastro-intestinal reflux into the trachea, and the collected secretions are removed by aspiration through a lumen provided in the ventilation device. A one-way valve may be provided in the expandable cuff in order to permit exhalation through the larynx to assist in speech.

Description

technical field [0001] The present invention generally relates to medical devices and methods. More specifically, the present invention relates to devices, systems and methods for airway management using a tracheostomy tube. The invention also relates to a percutaneous access device that can be used to place a tracheostomy device or other medical device. Background technique [0002] A tracheostomy is a surgical procedure that creates an opening in a patient's windpipe (windpipe) to provide a temporary or permanent passage for ventilation. Typically, a tube is inserted through the opening, allowing the passage of air and optionally removing secretions. The patient will breathe directly through the "airway" instead of through the nose and mouth. A tracheostomy is often performed in the setting of dyspnea and / or upper airway obstruction, and when the patient is unable to breathe spontaneously, the airway tube can be connected to a mechanical ventilator. [0003] The airway...
