A system for attaching an access port to bodily tissue, the system comprising: an access port assembly including an access port having a generally central axis and including a bottom, a sidewall and a needle penetratable septum, an access port housing generally containing the access port, an attachment mechanism structured to enable the access port to be attached to bodily tissue, wherein the attachment mechanism includes a plurality of rotatable anchors having a deployed position and an undeployed position, so that when in the deployed position, the anchors fix the access port to bodily tissue, and wherein the attachment mechanism is reversible so as to allow the access port assembly to be detached from tissue, characterized by: a rotating activator comprising a plurality of first and second protrusions for actuating deployment of the anchors upon rotation of the rotating activator of the access port housing, wherein each anchor comprises a pivotal proximal portion and a curved distal portion, the pivotal proximal portion being rotatably connected to the access port housing, and the curved distal portion for engaging tissue when the anchor is in the deployed position, the pivotal proximal portion being substantially perpendicular with a plane in which the curved distal portion rotates when the anchors are moved into the deployed position, and wherein the distal portion of each of the anchors is received between respective first and second protrusions of the rotating activator. an access port assembly including an access port having a generally central axis and including a bottom, a sidewall and a needle penetratable septum, an access port housing generally containing the access port, an attachment mechanism structured to enable the access port to be attached to bodily tissue, wherein the attachment mechanism includes a plurality of rotatable anchors having a deployed position and an undeployed position, so that when in the deployed position, the anchors fix the access port to bodily tissue, and wherein the attachment mechanism is reversible so as to allow the access port assembly to be detached from tissue, characterized by: a rotating activator comprising a plurality of first and second protrusions for actuating deployment of the anchors upon rotation of the rotating activator of the access port housing, wherein each anchor comprises a pivotal proximal portion and a curved distal portion, the pivotal proximal portion being rotatably connected to the access port housing, and the curved distal portion for engaging tissue when the anchor is in the deployed position, the pivotal proximal portion being substantially perpendicular with a plane in which the curved distal portion rotates when the anchors are moved into the deployed position, and wherein the distal portion of each of the anchors is received between respective first and second protrusions of the rotating activator. a rotating activator comprising a plurality of first and second protrusions for actuating deployment of the anchors upon rotation of the rotating activator of the access port housing, wherein each anchor comprises a pivotal proximal portion and a curved distal portion, the pivotal proximal portion being rotatably connected to the access port housing, and the curved distal portion for engaging tissue when the anchor is in the deployed position, the pivotal proximal portion being substantially perpendicular with a plane in which the curved distal portion rotates when the anchors are moved into the deployed position, and wherein the distal portion of each of the anchors is received between respective first and second protrusions of the rotating activator.
