  • Patent number: 9717895
    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.

  • Patent number: 9681823
    Abstract: An integrated catheter placement system for accurately placing a catheter within a patient's vasculature is disclosed. In one embodiment, the integrated system comprises a system console, a tip location sensor for temporary placement on the patient's chest, and an ultrasound probe. The tip location sensor senses a magnetic field of a stylet disposed in a lumen of the catheter when the catheter is disposed in the vasculature. The ultrasound probe ultrasonically images a portion of the vasculature prior to intravascular introduction of the catheter. The ultrasound probe includes user input controls for controlling use of the ultrasound probe in an ultrasound mode and use of the tip location sensor in a tip location mode. In another embodiment, ECG signal-based catheter tip guidance is included in the integrated system to enable guidance of the catheter tip to a desired position with respect to a node of the patient's heart.

  • Publication number: 20170157383
    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.

  • Publication number: 20150101616
    Abstract: A procedure kit that removably retains components to be used during a medical procedure, such as the insertion of a catheter into a patient, is disclosed. The procedure kit is securable to a surface or structure such that the kit is positioned as desired by the clinician, thus minimizing chances that the kit will fall to the ground or undesirably move. In one embodiment, the procedure kit comprises a body defining a plurality of pockets that are sized to removably receive therein components for use in the medical procedure, an openable flap that covers at least a portion of the pockets; and an adhesive portion included on a portion of the body to enable the procedure kit to be secured to a structure or surface proximate to the patient, such as the sterile drape covering the patient.

  • Publication number: 20150025478
    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.

  • Publication number: 20140378942
    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.

  • Publication number: 20140207086
    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.
