  • Patent number: 10463845
    Abstract: A low-profile access port for subcutaneous implantation within the body of a patient is disclosed. The access port includes a receiving cup that provides a relatively large subcutaneous target to enable a catheter-bearing needle to access the port without difficulty. In addition, the access port includes a valve/seal assembly to permit pressurized fluid injection through the port while preventing backflow. In one embodiment, therefore, a low-profile access port comprises a body including a conduit with an inlet port at a proximal end thereof, and a receiving cup. The receiving cup is concavely shaped to direct a catheter-bearing needle into the conduit via the inlet port. The receiving cup is oriented substantially toward a skin surface when subcutaneously implanted within the patient to ease needle impingement thereon. A valve/seal assembly disposed in the conduit enables passage of the catheter therethrough while preventing fluid backflow.

  • Publication number: 20190111242
    Abstract: An access port for providing subcutaneous access to a patient is disclosed. In one embodiment, the port includes an internal body defining a fluid cavity that is accessible via a septum. A compliant outer cover including silicone is disposed about at least a portion of the body. A flange is included with the port body and is covered by the outer cover. The flange radially extends about a perimeter of the port body proximate the septum so as to impede penetration of a needle substantially into the outer cover in instances where the needle misses the septum. The flange can further include both an anchoring feature for securing the outer cover to the port body and an identification feature observable via x-ray imaging technology for conveying information indicative of at least one attribute of the access port.

  • Patent number: 10130803
    Abstract: An access port for subcutaneous implantation into a body of a patient is disclosed. The port is typically subcutaneously connected to a catheter, a distal portion of which is disposed within a vein or other vessel of the patient. The port is configured with enhanced fluid handling features to improve fluid flow therethrough while reducing the likelihood of clotting or occlusions in the attached catheter, thus improving system patency. In one embodiment, for instance, an implantable access port is disclosed and comprises a body defining a reservoir, a needle-penetrable septum covering an opening to the reservoir, a stem defining an outlet to the reservoir, and a deformable element included in the reservoir. The deformable element is operably connected to a main portion of the septum and deforms in response to displacement of the septum to counteract a change in volume within the reservoir and prevent blood ingress into the catheter.

  • Patent number: 10086186
    Abstract: An implantable multi-lumen access port including indicators for ascertaining characteristics of the port is disclosed. In one embodiment, the access port comprises a housing that defines a first reservoir and a second reservoir. A first septum and second septum are respectively coupled with the housing to provide selective access to the first and second reservoirs. Each septum includes a plurality of protrusions defined about a periphery thereof that are palpable after implantation of the port in a patient to determine a relative position of the first septum with respect to the second septum. A radiographically observable indicator is also included on a base of the housing, so as to provide information relating to a characteristic of the dual-lumen port, such as suitability for power injection of fluids. The indicator in one embodiment includes a substantially rigid radiopaque component.
