Medical access ports, transfer devices and methods of use thereof
First Claim
1. A medical system, comprising:
- an implantable access port configured to be implanted into a subject, the access port including an implantable access port body and at least one implantable access port needle;
wherein the at least one needle comprises a needle shaft with a needle lumen, and a first needle tip which is connectable to and removable from the needle shaft;
wherein the needle lumen is closed by the first needle tip when the first needle tip is connected to the needle shaft;
wherein the at least one needle is concealable inside the access port body in a concealed position and is exposable outside the access port body in an exposed position;
wherein the at least one needle is arranged within the access port body to penetrate outwardly through skin of the subject from within the subject when the access port is implanted in the subject;
a transfer device configured to transfer a fluid to and/or from the subject through the access port when coupled with the at least one needle of the access port;
wherein the transfer device includes a fluid flow passage configured to transfer the fluid to and/or from the subject through the access port;
wherein the transfer device is configured to receive the at least one needle with the first needle tip connected to the needle shaft, such that the first needle tip and the needle shaft are within the fluid flow passage; and
wherein the transfer device is configured to remove the first needle tip from the needle shaft while the first needle tip and the needle shaft are within the fluid flow passage.

19. A method of treating a subject, comprising:
-
extending at least one needle through skin of the subject from an access port implanted beneath the skin of the subject such that the at least one needle penetrates the skin outward from within the subject to provide an exposed needle portion outside the subject, wherein the exposed needle portion comprises a needle shaft with a needle lumen, and a first needle tip which is connected to the needle shaft, and wherein the needle lumen is closed by the first needle tip when the first needle tip is connected to the needle shaft; and coupling a transfer device to the exposed needle portion, wherein the transfer device is configured to transfer a fluid to and/or from the subject through the access port when coupled with the at least one needle of the access port, wherein the transfer device includes a fluid flow passage configured to transfer the fluid to and/or from the access port; receiving the first needle tip and the needle shaft within the fluid flow passage with the first needle tip connected to the needle shaft; removing the first needle tip from the needle shaft while the first needle tip and the needle shaft are within the fluid flow passage; and transferring the fluid to and/or from the subject through the fluid flow passage of the transfer device.
