Abstract
An improved method and device are provided for forming and/or maintaining a percutaneous access pathway. The device generally comprises at least one of three type of components: access pathway, insertion device, and attachment device. In one embodiment, the device is used to form and/or maintain a percutaneous access pathway into the pleural cavity (i.e. tube thoracostomy). The provided assembly substantially reduces the possibility of iatrogenic infection while accessing and/or re-accessing a body space.
Claims19
A device for forming and/or maintaining a percutaneous access pathway into a body of a patient, comprising:
- an access pathway catheter configured to connect an internal portion of a body of a patient to an external environment, the access pathway catheter including a distal opening configured to extend at least partially into the internal portion of the body;
- an access pathway port configured to maintain a barrier between the internal portion of the body and the external environment when in a closed position, the access pathway port including at least one distal opening connecting to the access pathway catheter;
- an attachment device connectable to the access pathway port and configured to selectively allow the access pathway port to open by opening one or more doors in the access pathway;
- and
- a collapsible attachment device sheath at least partially surrounding the attachment device and configured to enable insertion of at least part of the attachment device into the internal portion of the body through the one or more doors in the access pathway when the attachment device is connected to the access pathway port.

- an access pathway door;
- an attachment device connectable to the access pathway port and configured to selectively allow the access pathway port to open by opening the access pathway door;
- and
- a collapsible attachment device sheath at least partially surrounding the attachment device and configured to enable insertion of at least part of the attachment device into the internal portion of the body through the door in the access pathway when the attachment device is connected to the access pathway port,
- wherein the access pathway door is configured to open only when the attachment device is attached to the access pathway port and to prohibit disconnection of the attachment device from the access pathway port when the access pathway door is open.
