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.

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.

Systems and methods for radiographically identifying an access port

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.

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.

Assemblies for identifying a power injectable access port

An access port for subcutaneous implantation is disclosed. Such an access port may comprise a body for capturing a septum for repeatedly inserting a needle therethrough into a cavity defined within the body. Further, the access port may 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. Further, the subcutaneously implanted access port may be identified in response to perceiving the at least one feature.

Access port identification systems and methods

A method of performing a power injection procedure, including taking an x-ray of a subcutaneously implanted access port in a patient to determine whether the access port includes a radiographic feature indicating that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the access port. The access port defines one or more fluid reservoirs, each fluid reservoir accessible through a cannula-penetrable septum. The method further includes identifying the indicating radiographic feature on the x-ray, and in accordance with the presence of the indicating feature on the x-ray, flowing a fluid through the access port at a rate of at least about 1 milliliter per second.

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, 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. The power-injectable access port is structured for operation at a pressure in the reservoir of at least 35 psi.

An access port for subcutaneous implantation is disclosed.

A guidance system for assisting with the insertion of a needle or other medical component into the body of a patient is disclosed. The guidance system utilizes ultrasound imaging or other suitable imaging technology. In one embodiment, the guidance system comprises an imaging device including a probe for producing an image of an internal body portion target, such as a vessel. One or more sensors are included with the probe. The sensors sense a detectable characteristic related to the needle, such as a magnetic field of a magnet included with the needle. The system includes a processor that uses data relating to the detectable characteristic sensed by the sensors to determine a position and/or orientation of the needle in three spatial dimensions. The system includes a display for depicting the position and/or orientation of the needle together with the image of the target.

A method of power injecting a contrast medium into a patient, including obtaining a power-injectable access port suitable for power injection. The power injectable access port includes a housing defining a reservoir, and a septum. The septum may include a self-sealing material, and a radiopaque material. The radiopaque material may form 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 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 to prevent exposure to a clinician.
