Surgical instruments and techniques are provided for creating a pneumostoma through the chest wall into the lung of a patient. The pneumostomy instruments and techniques may be used to create a pneumostoma which allows gases to escape from the lung through the chest wall and thereby treat chronic obstructive pulmonary disease.

Surgical instruments for creating a pneumostoma and treating chronic obstructive pulmonary disease

A two-phase surgical procedure is disclosed for creating a pneumostoma to treat chronic obstructive pulmonary disease The first phase is a procedure to induce creation of a localized pleurodesis and is preferably performed as an outpatient procedure. The second phase is a procedure to introduce a surgical instrument into the lung via the pleurodesis to create the pneumostoma. An interval of about one of more days between the first and second phases allows the formation of a stable pleurodesis to prevent pneumothorax during the procedure.

Two-phase surgical procedure for creating a pneumostoma to treat chronic obstructive pulmonary disease

A single-phase surgical procedure is disclosed for creating a pneumostoma to treat chronic obstructive pulmonary disease. In a single-phase technique the pleurodesis is formed at the same time as the pneumostoma and does not require a separate step. The thoracic cavity is accessed to visualize the lung, the pneumostomy catheter is inserted into the lung and then the lung is secured to the channel through the chest wall creating a sealed anastomosis which matures into a pleurodesis after the procedure.

Single-phase surgical procedure for creating a pneumostoma to treat chronic obstructive pulmonary disease

A pneumostoma assessment and treatment system includes methods and devices for aftercare of a pneumostoma. In particular, methods and devices are provided for standardized monitoring and assessment of pneumostoma patency thereby facilitating the establishment of standards-based protocols for pneumostoma management. Methods of standardized pneumostoma patency assessment includes the use of devices for raising alveolar pressure to a controlled repeatable pressure above ambient while analyzing gas flow through the pneumostoma. In response to an assessment the functionality of the pneumostoma, the tissues of the pneumostoma may be treated with a treatment device utilizing one or more different modalities to preserve or enhance the health and function of the pneumostoma.

Methods and devices for assessment of pneumostoma function

A flexible pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management device includes flange attaches to the chest of the patient to secure the device in position. The pneumostoma management device also includes a tube which enters the pneumostoma to allow gases to escape the lung. The length of the tube is selected to match the dimensions of the pneumostoma of a patient. In order to manufacture devices having different tube lengths, the tube is formed at a longer length than required, cut to size and tipped. The tube may be formed by molding or extrusion.

Variable length pneumostoma management system for treatment of chronic obstructive pulmonary disease

A pneumostoma management system which includes a pneumostoma management device and a cover. The pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management device includes a hydrophobic filter and/or a one-way filter. The cover serves to protect the pneumostoma management device and/or provide a cosmetic skin to make the pneumostoma management device more acceptable to the patient and thereby encourage patient compliance with a pneumostoma treatment regimen.

Pneumostoma management system having a cosmetic and/or protective cover

A flexible pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management device includes a pneumostoma vent having a tube which enters the pneumostoma to allow gases to escape the lung, a flange and a filter/valve to control flow of materials through the tube. The flange is a thin flexible patch which conforms and attaches to the chest of the patient. The flange secures the tube in position in the pneumostoma. The flange is formed in one piece with the tube.

One-piece pneumostoma management system and methods for treatment of chronic obstructive pulmonary disease

A pneumostoma management system for maintaining the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management system includes a two-part pneumostoma management device and associated insertion and removal tools. The pneumostoma management device includes a pneumostoma vent and a chest mount for positioning and securing the vent into a pneumostoma. The pneumostoma vent includes a hydrophobic filter and/or a one-way valve.

A flexible pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management device includes a pneumostoma vent having a tube which enters the pneumostoma to allow gases to escape the lung, a flange and a filter/valve to control flow of materials through the tube. The flange is a thin flexible patch comprises of multiple thin layers of materials and which conforms and attaches to the chest of the patient. The flange includes a filter, a protective outer layer and an inner hydrocolloid layer. The flange secures the tube in position in the pneumostoma.

Multi-layer pneumostoma management system and methods for treatment of chronic obstructive pulmonary disease

A pneumostoma management system includes a pneumostoma management device for maintaining the patency of a pneumostoma while controlling the flow of material through the pneumostoma and a pneumostoma aspirator for pneumostoma care. The pneumostoma aspirator includes a bulb or syringe for applying positive or negative pressure, a tube for entering the pneumostoma and a limiting device for limiting the depth of insertion of the tube into a pneumostoma. The pneumostoma aspirator may also be used to introduce irrigation fluid into the pneumostoma and/or remove irrigation fluid and discharge from the pneumostoma.

Aspirator for pneumostoma management

A flexible pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management device includes a pneumostoma vent having a tube which enters the pneumostoma to allow gases to escape the lung, a flange and a filter/valve to control flow of materials through the tube. The flange is a thin flexible patch comprises of multiple thin layers of materials and which conforms and attaches to the chest of the patient. The flange includes a filter, a protective outer layer and an inner hydrocolloid layer. The flange secures the tube in position in the pneumostoma. An indicator responsive to gases exiting the pneumostoma is integrated into the device and provides and external indicia of the patency and efficacy of the pneumostoma.

Pneumostoma management device with integrated patency sensor and method

A flexible pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management device includes a pneumostoma vent having a tube which enters the pneumostoma to allow gases to escape the lung, a flange and a filter/valve to control flow of materials through the tube.
