  • 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: 20190275311
    Abstract: An access port includes an access port body and a needle-penetrable septum. The access port body can be of integral single-piece construction, and can define a reservoir aligned with an access opening. The access port body can further define an annular groove between the reservoir and the opening. The annular groove can have a diameter greater than a diameter of the access opening and a diameter of the reservoir. The needle-penetrable septum can include an upper portion disposed in the access opening and an annular flange disposed in the annular groove. The annular flange can extend radially outward from a lower portion of the septum, and can have a diameter greater than a diameter of the upper portion of the septum. The needle-penetrable septum can further include an annular reinforcement structure disposed within the annular flange.

  • Publication number: 20190252603
    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.

  • Patent number: 10307581
    Abstract: A septum for sealably covering a fluid cavity defined in an implantable device, which may be an access port, and methods for assembling the implantable device. The septum may include a resilient septum body, an annular flange extending radially outward from the septum body, and a reinforcement component disposed in the annular flange for reinforcing engagement with a corresponding annular groove defined in a body of the implantable device. The reinforcement component may inhibit unintended detachment of the septum from the implantable device.

  • Patent number: 10016585
    Abstract: A power-injectable access port suitable for providing subcutaneous access to a patient and suitable for power injection. The access port includes a septum, a housing, and a reservoir defined by the septum and the housing. The septum may include a material that seals passages formed by puncturing the septum with a hollow slender element or another suitable access mechanism, and a radiopaque material forming a selected pattern when an x-ray is taken through the septum for identifying the power-injectable access port as being suitable for power injection. The housing and the septum may be structured for accommodating a pressure developed within the reservoir of at least 35 psi. The power-injectable access port may be designed to accommodate a flow rate of at least 1 milliliter per second of a fluid.

  • Patent number: 9937337
    Abstract: A power-injectable access port suitable for injecting contrast media therethrough at a rate of at least 1 milliliter per second. The access port includes a housing, a septum, a reservoir, and an outlet stem in fluid communication with the reservoir. The power-injectable access port is structured for accommodating a pressure developed within the reservoir of at least 35 psi. The septum may include a radiopaque material forming a selected pattern when an x-ray is taken through the septum. The pattern may identify the access port as capable of accommodating injection of contrast media at a rate of at least 1 milliliter per second and/or as capable of accommodating a pressure developed within the reservoir of at least 35 psi. The pattern may identify the location of the septum following implantation of the power-injectable access port.

  • Patent number: 8636700
    Abstract: A catheter assembly includes a catheter, a tubular structure affixed to an exterior surface of the catheter, and a stabilizing cuff affixed to, and at least partially embedded within, the tubular structure. The tubular structure may include a tapered surface extending from an end of the tubular structure to an exterior surface of the catheter. A method of manufacturing a catheter assembly may include positioning a tubular structure about a catheter, positioning a stabilizing cuff near the tubular structure, and partially embedding at least a portion of the stabilizing cuff within the tubular structure while shaping the tubular structure to form a tapered surface. A temporary sleeve may be positioned about the tubular structure prior to shaping the tubular structure. The tubular structure may also be preformed to include a tapered end prior to positioning the tubular structure about the catheter.

  • Publication number: 20110288502
    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.
