  • 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.

  • 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. The outer cover provides a suitable surface for application of an antimicrobial/antithrombotic coating.

  • Publication number: 20190060628
    Abstract: A method for power injection of fluids through an access port includes implanting the access port in a patient, palpating the access port, imaging the access port, and introducing contrast media into the patient through the access port at a rate in a range from about two milliliters per second to about five milliliters per second. The access port may include a housing, a first septum, a second septum, and a radiographic indicator. The first septum and the second septum may respectively cover a first reservoir and a second reservoir of the access port. The first septum may include a first sub-pattern of protrusions and the second septum may include a second sub-pattern of protrusions. The radiographic indicator may include a first portion including information pertaining to the first sub-pattern, and a second portion including information pertaining to the second sub-pattern. The imaging identifies the radiographic indicator.

  • 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.

  • 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.

  • Publication number: 20180078751
    Abstract: A low-profile access port for subcutaneous implantation within a patient is disclosed. The access port includes a receiving cup that provides a relatively large subcutaneous target to enable catheter-bearing needle access to the port without difficulty. In one embodiment, a low-profile access port comprises a body including a conduit with an inlet port at a proximal end, and a receiving cup. The receiving cup is funnel shaped to direct a catheter-bearing needle into the conduit via the inlet port. The conduit is defined by the body and extends from the inlet port to an outlet defined by a stem. A bend in the conduit enables catheter advancement past the bend while preventing needle advancement. A valve/seal assembly is also disposed in the conduit and enables passage of the catheter therethrough while preventing fluid backflow. The body includes radiopaque indicia configured to enable identification of the access port via x-ray imaging.
