  • Patent number: 11511097
    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.

  • Patent number: 11504515
    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.

  • Patent number: 11491276
    Abstract: Release of a neurological drug in a targeted region of a subject's brain by a drug delivery system (DDS) is intentionally caused by the subject watching or interacting with an audio/video-based task on an electronic display. The DDS is calibrated to release the neurological drug based on a particular pH, lactate level, blood flow, temperature, magnetic field, specific molecules released by brain cells, or other physiological factors within the target region. The interactive task produces the physiological factors in the brain in specific areas of pathology for which the drug is prescribed, and limits drug delivery at areas unaffected by illness where it could disrupt normal function, causing problematic side effects and preventing dose levels optimal for target impact. Feedback from the interactive task and associated cognitive probes also can adapt the interactive task or suggest new pharmacologic agents as the degree or primary focus of brain pathology changes during the course of treatment.
