Patent number: 10857340Abstract: A power-injectable access port and methods of making are described. One method of making includes forming a power-injectable access port housing, creating a screen including one or more apertures through the screen in the shape of one or more alphanumeric characters, suspending a radiopaque material in a silicone material to form a radiopaque suspension, and depositing the radiopaque suspension onto a surface of the power-injectable access port housing through the one or more apertures of the screen to create at least one radiopaque identification feature. The at least one radiopaque identification feature may have a thickness protruding from an outer surface of the port base such that it is perceivable by sight and touch prior to implantation of the power injectable access port, and is observable via imaging technology subsequent to subcutaneous implantation of the power-injectable access port.Type: GrantFiled: January 7, 2019Date of Patent: December 8, 2020Assignee: Bard Peripheral Vascular, Inc.Inventors: William R.

Patent number: 10780257Abstract: A method of treating a patient using a power-injectable access port, including implanting the power-injectable access port in the patient, imaging the power-injectable access port following implanting, and power injecting a fluid into the patient through the power-injectable access port. The power-injectable access port includes a septum covering a reservoir, the septum including a radiopaque material forming at least one letter, the at least one letter indicating that the power-injectable access port is suitable for power injection. The power-injectable access port is designed to accommodate a pressure developed within the reservoir of at least 35 psi, and a fluid flow rate of at least 1 milliliter per second. Imaging the power-injectable access port produces an image, and the method includes identifying the at least one letter on the image to confirm that the power-injectable access port is suitable for power injecting a fluid.Type: GrantFiled: January 18, 2019Date of Patent: September 22, 2020Assignee: Bard Peripheral Vascular, Inc.Inventors: Kelly B.
