Percutaneous access pathway system and method
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.
1. 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;
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 a distal opening through which the access pathway catheter is configured to extend into the internal portion of the body;
an attachment device connectable to the access pathway port and configured to selectively cause the access pathway port to open by opening one or more doors in the access pathway;
an internally sterile 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; and
an insertion device configured to cause the access pathway catheter to be inserted into the internal portion of the body of the patient, wherein the insertion device is configured to selectively cause the access pathway catheter to expand.
2. The percutaneous access pathway of claim 1 , wherein the one or more doors in the access pathway includes a door in the access pathway port that is configured to be reversibly opened and closed.
3. The percutaneous access pathway of claim 1 , wherein the attachment device is configured to be reversibly connected to and disconnected from the access pathway port.
4. The percutaneous access pathway of claim 1 , wherein the attachment device is configured to be manipulated from the external environment through the attachment device sheath while maintaining a barrier from the external environment to within the body with the access pathway port and the attachment device sheath.
5. The percutaneous access pathway of claim 1 , wherein the internal portion of the patient's body is the chest cavity.
6. The percutaneous access pathway of claim 1 , wherein the access pathway catheter and access pathway port are unitarily formed as a single component.
7. The percutaneous access pathway of claim 1 , wherein the access pathway is configured to be used for a tube thoracostomy.
8. The percutaneous access pathway of claim 1 , wherein the internal portion of the patient's body is inside the abdominal cavity, trachea, skull, bone, vessel, bladder, a hollow organ, abscess, and/or a collection of fluid in the body.
9. The percutaneous access pathway of claim 1 , wherein the access pathway functions as a standard catheter, Penrose drain, pigtail catheter, chest tube, tracheostomy tube, endotracheal tube, venous or arterial catheter, thoracentesis tube, paracentesis tube, abscess drainage or other medical tube, and/or a catheter for placement into a body cavity.
10. The percutaneous access pathway of claim 1 , wherein the access pathway is used for placing an access pathway into an abdominal cavity, abscess, thoracic cavity, cranium, bone, trachea, vein, and/or artery.
11. The percutaneous access pathway of claim 2 , wherein the access pathway is configured to enable opening of the door in the access pathway port when the attachment device is connected to the access pathway port.
12. The percutaneous access pathway of claim 2 , wherein the access pathway is configured to inhibit removal of the attachment device from the access pathway port while the door in the access pathway port is open.
13. The percutaneous access pathway of claim 1 , wherein the attachment device is configured to connect to suction in the external environment.
14. The percutaneous access pathway of claim 1 , wherein the attachment device sheath is air-impermeable.
15. The percutaneous access pathway of claim 1 , wherein the access pathway port and/or access pathway catheter contain an adhesive configured to secure the access pathway to the body of a patient.
