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 adjusting and/or replacing a chest tube after initial insertion into a body of a patient, comprising:
an access pathway port configured to maintain a barrier between an internal portion of the body and an external environment when in a closed position; and
an attachment device configured to at least partially contain a chest tube, the attachment device being connectable to the access pathway port and configured to allow the access pathway port to open,
wherein the access pathway port and the attachment device cooperate to only allow the access pathway port to open at the time that the attachment device is attached to the access pathway port and automatically prohibit disconnection of the attachment device from the access pathway port when the access pathway port is open.
2. The device of claim 1 , further comprising an attachment device sheath at least partially surrounding the attachment device and configured to enable insertion of the chest tube into the internal portion of the body through the access pathway port.
3. The device of claim 2 , wherein the chest tube 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.
4. The device of claim 2 , wherein the attachment device sheath is collapsible.
5. The device of claim 2 , wherein the attachment device sheath is internally sterile and air-impermeable.
6. The device of claim 1 , wherein the chest tube is configured to connect to suction in the external environment.
7. The device of claim 1 , further comprising an access pathway catheter extending from the access pathway port into the internal portion of the body, and wherein the chest tube is configured to be inserted through the access pathway catheter into the body when the access pathway port is open.
8. The device of claim 7 , wherein the access pathway catheter and access pathway port are unitarily formed in a single component.
9. The device of claim 7 , further comprising an insertion device configured to cause the access pathway catheter to be inserted into the internal portion of the body.
10. The device of claim 9 , wherein the insertion device is configured to selectively cause the access pathway catheter to expand upon insertion of the access pathway catheter into the internal portion of the body.
11. The device of 10 , wherein the insertion device causes the access pathway catheter to expand by circumferentially dilating the access pathway catheter within a chest wall adjacent the internal portion of the body.
12. The device of claim 1 , wherein the access pathway port includes a means for securing the access pathway port to the patient.
13. The device of claim 12 , wherein the means for securing includes an adhesive.
14. A device for adjusting and/or replacing a chest tube after initial insertion into a body of a patient, comprising:
an access pathway port configured to maintain a barrier between an internal portion of the body and an external environment when in a closed position; and
an attachment device configured to at least partially contain a chest tube, the attachment device being connectable to the access pathway port and configured to allow the access pathway port to open;
an attachment device sheath at least partially surrounding the attachment device and configured to enable insertion of the chest tube into the internal portion of the body through the access pathway port, wherein the chest tube 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.
15. The device of claim 14 , wherein the attachment device sheath is collapsible.
16. The device of claim 14 , wherein the attachment device sheath is internally sterile and air-impermeable.
17. The device of claim 14 , wherein the chest tube is configured to connect to suction in the external environment.
18. The device of claim 14 , further comprising an access pathway catheter extending from the access pathway port into the internal portion of the body, and wherein the chest tube is configured to be inserted through the access pathway catheter into the body when the access pathway port is open.
19. The device of claim 18 , further comprising an insertion device configured to cause the access pathway catheter to be inserted into the internal portion of the body.
20. The device of claim 14 , wherein the access pathway port includes a means for securing the access pathway port to the patient.
