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.
Abstract translation: 公开了一种用于在患者体内进行皮下植入的小型入口。 进入端口包括接收杯，其提供相对较大的皮下靶，以使得导管支承针无困难地进入端口。 此外，进出口包括阀/密封组件，以允许通过端口加压流体喷射同时防止回流。 因此，在一个实施例中，低轮廓进入端口包括主体，其包括具有在其近端处的入口端口的导管和接收杯。 接收杯是凹形的，以通过入口将导管轴承针引导到导管中。 当皮下植入患者体内时，接收杯基本上朝向皮肤表面定向，以便在其上冲击针刺。 设置在导管中的阀/密封组件使得导管能够通过，同时防止流体回流。

Abstract: A septum for use in sealably covering a fluid cavity of an implantable medical device, such as an access port, is disclosed. The septum is resilient and includes a reinforcement structure that bolsters septum placement over the fluid cavity so as to inhibit unintended separation of the septum from the medical device when the fluid cavity is under pressure, such as during power injection of fluid into the fluid cavity. In one embodiment the septum comprises a resilient septum body that includes a flange disposed about a perimeter thereof. A reinforcement component is disposed in the flange for reinforcing engagement of the flange with a corresponding groove defined about an opening to the fluid cavity of the medical device so as to inhibit unintended detachment of the septum from the medical device. The reinforcement component in one embodiment includes an annular cord disposed in the flange.

Abstract: An access port for subcutaneous implantation is disclosed. The access port may include a body for capturing a septum for repeatedly inserting a needle therethrough into a cavity defined within the body. The access port may further include at least one feature structured and configured for identification of the access port subsequent to subcutaneous implantation. Methods of identifying a subcutaneously implanted access port are also disclosed. For example, a subcutaneously implanted access port may be provided and at least one feature of the subcutaneously implanted access port may be perceived. The subcutaneously implanted access port may be identified in response to perceiving the at least one feature. In one embodiment, an identification feature is included on a molded insert that is sandwiched between base and cap portions of the access port so as to be visible after implantation via x-ray imaging technology.
