Abstract: A catheter assembly for regulation or transfer of fluids to and from a patient. The catheter assembly may include a catheter and a valve assembly. The valve assembly may include a diaphragm having two unidirectional slit valves that open in different directions, a first unidirectional slit valve opening distally in response to an infusion-induced pressure and a second unidirectional slit valve opening proximally in response to an aspiration-induced pressure.

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. The identification feature can be included on a molded insert.

Abstract: A power injectable port assembly for use with a power injector system, including a power injectable port. The power injectable port can include a body formed from a bio-compatible plastic material, and can include a cap and a base. A septum is captured between the cap and the base and is accessible through an opening in the cap. The base can define a cavity and the septum can be positioned over the cavity. The base can include a lower surface with a radiopaque identification feature observable via imaging technology subsequent to subcutaneous implantation of the power injectable port.

Abstract: A power-injectable access port can include a power-injectable access port cap including an opening and a power-injectable access port base including a reservoir corresponding to the opening. The power-injectable access port can further include a septum corresponding to the reservoir. The septum can include a bottom surface covering the reservoir and a top surface extending through the opening in the power-injectable access port cap. The power-injectable access port can include a radiopaque identification feature indicating that the power-injectable access port is suitable for power injection. The radiopaque identification feature can be a suspension of a radiopaque material in a silicone material positioned on an outer surface of the power-injectable access port base.

Abstract: A catheter connector assembly which may be included with a corporeal drainage system, and a method of draining fluid from a bodily cavity. The catheter connector assembly may include a catheter connector and a drainage line connector. The catheter connector may include a connector body with a coupling feature, a deformable sealing element, and a retaining member. The drainage line connector may include a drainage line body first and second hinge clips, and an actuator. The actuator is designed to deform the deformable sealing element when the drainage line connector is coupled to the catheter connector.

Abstract: A method for manufacturing an implantable access port, including forming a port body. The port body can include a fluid cavity located in a central region, the fluid cavity having a base surface lying in a first plane, and a plurality of recessed sections located in a peripheral region surrounding the central region, the plurality of recessed sections having a depth extending from a bottom surface of the peripheral region through the first plane. The method further includes locating a septum over the fluid cavity, and positioning a radiopaque insert in the plurality of recessed sections.

Abstract: 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.

Abstract: 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.

Abstract: A method of using a power-injectable port includes obtaining the power-injectable access port, attaching a catheter to an outlet stem of the power-injectable access port, and implanting the power-injectable access port and the catheter into a patient. The method further includes identifying the power-injectable access port following the implanting, and in accordance with the identification, inserting a distal end of a needle through the septum and into the reservoir, and injecting contrast media through the needle at a rate of at least one milliliter per second. The power-injectable 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 rated for injection of contrast media at a flow rate of at least 1 milliliter per second.
