Implantable access port device and attachment system
First Claim
1. A system for attaching an access port to bodily tissue, the system comprising:
- an access port assembly including;
i. an access port having a generally central axis and including a bottom, a sidewall and a needle penetrable septum; and
ii. an attachment mechanism structured to enable the access port to be attached to bodily tissue; and
a delivery tool including;
i. a delivery head structured to engage the access port assembly, the delivery head having a longitudinal sidewall extending parallel to the central axis when the delivery head engages the access port;
ii. a handle having a distal portion extending laterally away from the longitudinal sidewall of the delivery head and having a moveable trigger extending from a proximal portion of the handle, the handle defining an internal pathway in which a pair of opposingly movable cable portions extend side-by-side, the cable portions extending from the delivery head into the internal pathway of the handle, the cable portions being oppositely longitudinally moveable side-by-side relative to each other in the internal pathway and in the delivery head by movement of the trigger; and
iii. an activation mechanism coupled to the trigger for selectively enabling deployment and retraction of the attachment mechanism by movement of the trigger and a respective one of the cable portions when the delivery head is so engaged with the access port assembly.

Abstract
A system for attaching an access port to bodily tissue includes an access port assembly and including an access port having a generally central axis. The access port assembly further includes an attachment mechanism structured to enable the access port to be attached, for example, to an abdominal muscle of a patient. The delivery tool includes a handle having a generally longitudinal axis and a delivery head structured to engage the access port assembly, and an activation mechanism for enabling deployment of the attachment mechanism when the delivery head is so engaged with the access port assembly. The delivery tool is configured such that the longitudinal axis of the handle is spaced apart from the generally central axis of the access port when the delivery head is so engaged with the access port assembly.

15. A delivery tool for attaching an access port assembly to bodily tissue, the access port assembly including deployable fasteners and an access port having a generally central axis, the tool comprising:
-
a delivery head structured to engage the access port assembly, the delivery head having a longitudinal sidewall extending parallel to the central axis when the delivery head engages the access port; a handle having a distal portion extending laterally away from the longitudinal sidewall of the delivery head and having a moveable trigger extending from a proximal portion of the handle, the handle defining an internal curved pathway in which a pair of opposingly movable cable portions extend side-by-side, the cable portions extending from the delivery head into the internal pathway of the handle, the cable portions being oppositely longitudinally displaceable side-by-side relative to each other by movement of the trigger; and an activation mechanism coupled to the trigger for selectively enabling deployment and retraction of the deployable fasteners by movement of the trigger and a respective one of the cable portions when the delivery head is so engaged with the access port assembly, wherein movement of the trigger is constructed to longitudinally displace a respective one of the cable portions in the internal pathway of the handle and in the delivery head to rotate a rotatable portion of the access port assembly when the delivery head is engaged to the access port assembly to move the deployable fasteners relative to the access port assembly, and wherein each of the cable portions has a substantially straight proximal portion and a curved distal portion. - View Dependent Claims (16, 17)
