Abstract
Described herein is an implantable access port device with a catheter compartment which permits lengthening or shortening the catheter in response to changes in tension of the distal catheter. Implantable access port devices are used extensively in the medical field to facilitate the performance of recurrent therapeutic tasks such as repeated drug delivery, drainage, blood sampling, transfusions, or total parental nutrition. In current access port systems, the catheter is rigidly attached to the access port via a connection ring. As such, the system does not provide any flexibility or ability for catheter length adjustments, which can lead to long-term complications such as dislodgement of catheters, migration of catheters, port separation with extravasation, suture disruption, and mechanical failure of the access port system. These catheter-related complications carry serious risks for the patients. The implantable access port system described herein permits self-adjusting catheter length, thereby reducing catheter-related complications.
