Abstract

A percutaneous port comprises a port body defining a cavity and a first catheter channel adapted to allow passage of a catheter thereinto a shuttle removably received within the cavity, the shuttle including a first flow conduit which, when the shuttle is received within the cavity, extends to the first catheter channel and a sealing mechanism sealing the first flow conduit when a fluid pressure applied thereto is less than a threshold value and opening to permit flow therethrough when the fluid pressure applied thereto is at least the threshold value a cover releasably attachable to the port body to enclose the cavity.

Claims

1. A percutaneous port comprising:

a port body defining a cavity and a first catheter channel adapted to allow passage of a catheter thereinto;

a shuttle removably received within the cavity, the shuttle including a first flow conduit which, when the shuttle is received within the cavity, extends to the first catheter channel and a sealing mechanism sealing the first flow conduit when a fluid pressure applied thereto is less than a threshold value and opening to permit flow therethrough when the fluid pressure applied thereto is at least the threshold value; and

a cover releasably attachable to the port body to enclose the cavity.

2. The percutaneous port according to claim 1, wherein the port body further comprises a plurality of retaining elements releasably locking the shuttle into the cavity.

3. The percutaneous port according to claim 1, wherein the port body further includes a flange extending from a perimeter thereof, the flange including at least one suture hole.

4. The percutaneous port according to claim 1, wherein the shuttle further comprises a sealing mechanism bypass communicating with the first flow conduit.

5. The percutaneous port according to claim 4, further comprising a cover of the sealing mechanism bypass to seal the first flow conduit.

6. The percutaneous port according to claim 1, wherein the first sealing mechanism comprises a PASV valve.

7. The percutaneous port according to claim 5, wherein the sealing mechanism bypass includes a passage extending therethrough sized to receive a guide wire.

8. The percutaneous port according to claim 1, further comprising a lip of the port body cooperating with the cover to retain the cover in place over the cavity.

9. The percutaneous port according to claim 1, further comprising a plurality of snaps releasably locking the cover to the port body.

10. The percutaneous port according to claim 1, wherein the cover comprises a mechanism to engage and disengage locking protrusions of the cover to slots of the port body.

11. The percutaneous port according to claim 1, wherein the shuttle further comprises a second flow conduit and a second sealing mechanism in fluid communication with the second flow conduit.

12. The percutaneous port according to claim 11, wherein the first and second sealing mechanisms are offset with respect to one another to minimize a dimension of the shuttle.

13. A method comprising:

connecting a catheter to a percutaneous port;

removing a cover of the percutaneous port to access a cavity therein;

detaching a shuttle from the port to access a catheter channel of the port wherein, coupled to the port, a flow conduit of the shuttle is in fluid communication with the catheter channel, the flow conduit remaining sealed at all times when a fluid pressure applied thereto remains below a threshold value;

extracting the catheter from the port through the catheter channel;

inserting a new catheter to a target site within the body through the catheter channel;

attaching the shuttle to the port so that the flow conduit is in fluid connection with the catheter; and

closing the percutaneous port with the cover.

14. The method according to claim 13, further comprising inserting a guidewire through a valve bypass of the shuttle.

15. The method according to claim 13, further comprising inserting a guidewire through a valve body of the shuttle.

16. The method according to claim 13, further comprising stabilizing the percutaneous port with sutures inserted through orifices of a flange of the port.

17. The method according to claim 13, further comprising filling the cavity with an antibacterial compound.

18. The method according to claim 13, further comprising attaching the catheter to the catheter channel.
