Abstract

Claims (15)

1. A device for forming and/or maintaining a percutaneous access pathway into a body of a patient, comprising:

an access pathway configured to allow access to an internal portion of a patient's body from an external environment, the access pathway comprising an access pathway port configured to maintain a non-pierceable barrier between the internal portion of the body and the external environment when in a closed position, wherein the access pathway port connects through a distal opening to an access pathway catheter extending at least partially into the internal portion of the body and allowing access into the internal portion of the body when the access pathway port is open; and

an attachment device connectable to the access pathway port and configured to open the access pathway port, the attachment device comprising an internally sterile attachment device sheath at least partially surrounding an internal equipment component of the attachment device, the attachment device sheath configured to enable insertion of at least part of the internal equipment component into the internal portion of the body through the access pathway when the attachment device is connected to the access pathway port.

2. The device of claim 1 , wherein the internal equipment component of the attachment device is a chest tube.

3. The device of claim 1 , wherein the attachment device includes a means for both irrigation and suction.

4. The device of claim 1 , wherein the internal equipment component of the attachment device includes an endoscope.

5. The device of claim 1 , wherein the internal equipment component of the attachment device includes one or more surgical tools.

6. The device of claim 1 , wherein the attachment device sheath is configured to enable manipulation of the internal equipment component through the attachment device sheath while maintaining a barrier from the external environment to within the body.

7. The device of claim 6 , wherein the attachment device sheath is air-impermeable.

8. The device of claim 1 , wherein the access pathway port includes a mobile pathway or door that moves to open and close an entrance to the access pathway.

9. The device of claim 8 , wherein the mobile pathway or door utilizes a cylinder, a sphere, a ball, or a ball-valve mechanism.

10. The device of claim 1 , wherein the attachment device can be reversibly connected to and disconnected from the access pathway port.

11. The device of claim 1 , wherein removal of the attachment device from the access pathway port is inhibited while the access pathway port is open.

12. The device of claim 1 , wherein the attachment device is configured to connect to suction in the external environment.

13. The device of claim 1 , wherein the access pathway contains a means for securing the access pathway to the body of a patient.
