Abstract

Provided herein is a system including, in some embodiments, a streamlined port and a port tunneler. The port includes a septum and a stabilizing element. The septum is disposed over a cavity in a body of the port, and the septum is configured to accept a needle therethrough. The stabilizing element is configured to stabilize the port in vivo and maintain needle access to the septum. The port tunneler includes an adapter and a release mechanism. The adapter is in a distal end portion of the port tunneler, and the adapter is configured to securely hold the port while subcutaneously tunneling the port from an incision site to an implantation site for the port. The release mechanism is configured to release the port from the adapter at the implantation site for the port.

First claim

What is claimed is:

1. A system, comprising:
a) a streamlined port including:
a septum disposed over a cavity in a body of the port configured to accept a needle therethrough; and
a stabilizing element configured to stabilize the port in vivo and maintain needle access to the septum; and

b) a port tunneler including:
an adapter in a distal end portion of the port tunneler configured to securely hold the port while subcutaneously tunneling the port from an incision site to an implantation site for the port; and
a release mechanism configured to release the port from the adapter at the implantation site.

2. The system of claim 1 , wherein the stabilizing element is an inflatable section of the port, the inflatable section including:
an uninflated state imparting a profile to the port configured for subcutaneously tunneling the port from the incision site to the implantation site for the port; and
an inflated state configured to stabilize the port from rolling about a central axis of the port in vivo, thereby maintaining needle access to the septum.

3. The system of claim 2 , wherein the inflatable section is configured to inflate with one or more fluids, one or more polymers, or a combination thereof, and the port tunneler further includes an inflation lumen fluidly connected to the inflatable section for inflating the inflatable section with the one or more fluids, the one or more polymers, or the combination thereof.

4. The system of claim 3 , wherein the port further includes a one-way valve configured to close off the inflatable section upon releasing the port from the port tunneler with the release mechanism.

5. The system of claim 2 , wherein the inflatable section is configured to inflate by introducing a solution including at least one polymer precursor that forms a polymer with at least one other polymer precursor after polymerization and cross linking within the inflatable section.

6. The system of claim 1 , wherein the stabilizing element is at least a pair of legs configured to stabilize the port from rolling about a central axis of the port in vivo, thereby maintaining needle access to the septum.

7. The system of claim 6 , wherein the at least a pair of legs is configured to assume a deployed state upon releasing the port from the port tunneler with the release mechanism, and the adapter is configured to hold a proximal end portion of the port including the at least a pair of legs in a collapsed state of the at least a pair of legs.

8. The system of claim 1 , wherein the stabilizing element is a winged bullet-type shape of the port configured to stabilize the port from rolling about a central axis of the port in vivo, thereby maintaining needle access to the septum.

9. The system of claim 1 , further comprising:
c) an installation tool configured to hold at least a distal end portion of the port for connecting a catheter to a proximal end portion of the port and facilitate installing the port in the adapter in the distal end portion of the port tunneler.
