Publication number: 20140378942Abstract: 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.Type: ApplicationFiled: June 19, 2014Publication date: December 25, 2014Inventors: Kelly J.

Publication number: 20140275918Abstract: A closed-ended catheter assembly that includes an electrically conductive pathway is disclosed. The conductive pathway enables electrical signals, such as ECG signals produced by a patient's heart, to pass through the closed-ended tip of the indwelling catheter while still preventing unintended fluid flow. In one embodiment, therefore, a catheter assembly is disclosed and comprises an elongate catheter tube including a closed distal end. The catheter tube defines at least one lumen and includes a valve defined in the catheter tube that is configured to selectively enable fluids to pass therethrough. The catheter tube includes a conductive element that provides an electrically conductive pathway between the at least one lumen and an exterior portion of the catheter. The conductive element includes a porous material extending between the at least one lumen and the exterior portion of the catheter, the porous material being transmissive to electrical signals and non-permeable to blood.Type: ApplicationFiled: March 13, 2014Publication date: September 18, 2014Applicant: C.

Publication number: 20140207086Abstract: 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.Type: ApplicationFiled: January 23, 2014Publication date: July 24, 2014Inventors: Jason R. Stats, Bret Hamatake, Dwight T. Hibdon, Kelly J. Christian, Amir Orome, Scott W. Snyder

Publication number: 20140107591Abstract: Multi-lumen catheters with improved tip configurations, including a triple-lumen catheter which may be useful for apheresis. In one variation, the catheter has three lumens with distal openings angularly spaced apart and staggered axially with respect to one another. In another variation, the catheter has two lumens exiting distally and one centrally positioned lumen exiting proximally. A third variation is a catheter with a single distal opening and two proximal openings. The staggered lumen openings along the axial length of the catheter may decrease recirculation while maximizing flow rates.Type: ApplicationFiled: December 12, 2013Publication date: April 17, 2014Applicant: C.

Publication number: 20140066894Abstract: A safety needle assembly of an infusion set is disclosed. The needle assembly is configured to prevent fluid/vapor escape therefrom so as to reduce or prevent fluid exposure to a clinician using the needle assembly. In one embodiment, the needle assembly comprises a handle portion including a needle extending therefrom, the needle defining a lumen for passage of a fluid therethrough. The needle assembly also includes a safety assembly defining a needle hole through which the needle initially extends. The safety assembly is selectively and axially slidable along the needle in order to shield a distal tip of the needle and prevent user contact therewith. A fluid isolation component is included in the safety assembly for isolating fluid escape from the needle. In one embodiment, the fluid isolation component includes a self-sealing pad that prevents needle leakage when the distal tip is shielded by the safety assembly.Type: ApplicationFiled: November 1, 2013Publication date: March 6, 2014Applicant: C.
