An access port including a housing, a first septum, a second septum, and a radiographic indicator. The first septum and the second septum can respectively cover a first reservoir and a second reservoir of the access port. The first septum can include a first sub-pattern of protrusions and the second septum can include a second sub-pattern of protrusions. The radiographic indicator can include a first portion including information pertaining to the first sub-pattern, and a second portion including information pertaining to the second sub-pattern.

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.

An implantable vascular access port has a main port body with one or more hollow internal chambers formed therein each with a floor at the base of the internal chamber. The port body has an outlet aperture formed in a sidewall there of the internal chamber. One or more parallel, lateral, or angled-access apertures, relative to the port floor and associated septa are located opposite the outlet aperture in the main port body in a sidewall there of (parallel or lateral or angled-access aperture or septum), with at least a one perpendicular-access aperture and septum located opposite the floor of the internal chamber(s). The port chamber in the area of the outlet aperture has an at least partially conical shape directionally aligned with the parallel or lateral or angled-access aperture and septum, with said outlet aperture in contiguity a reversible outlet tube or port body needle locking mechanism.

A method for power injection of fluids through an access port includes implanting the access port in a patient, palpating the access port, imaging the access port, and introducing contrast media into the patient through the access port at a rate in a range from about two milliliters per second to about five milliliters per second. The access port may include a housing, a first septum, a second septum, and a radiographic indicator. The first septum and the second septum may respectively cover a first reservoir and a second reservoir of the access port. The first septum may include a first sub-pattern of protrusions and the second septum may include a second sub-pattern of protrusions. The radiographic indicator may include a first portion including information pertaining to the first sub-pattern, and a second portion including information pertaining to the second sub-pattern. The imaging identifies the radiographic indicator.

Devices and methods for obtaining high flow rates in a port catheter system, and devices and methods for using a high flow rate port catheter system are disclosed. In one embodiment, a reservoir is dedicated for aspiration and a separate reservoir is dedicated for infusion. Fluid flow channels associated with aspiration are larger than the fluid flow channels associated with infusion. The catheter connected to the port can have an offset tip configuration. Methods for accessing the port are also disclosed.

A medical device comprises a flexible member that can be adhesively attached to a housing of the medical device, allowing implantation of the medical device into a body through an incision of reduced size. The flexible member can be attached to the housing either before or after implantation into the body. The flexible member comprises suture locations, including a permeable membrane or a suture hole, for suturing the medical device to tissue of the body. The suture holes can be filled with a substance penetrable by a suture needle, to minimize tissue ingrowth before or after suturing.

A venous access port assembly (10) having a housing base (28) with a discharge port (16), a septum (14) and a cap (48). An interior reservoir (22) is defined by a well (30) in the housing base and a bottom (62) of the septum, and a passageway (20) extends from the reservoir through the discharge port (16). The housing base (28) is provided with radiopaque markings (60) on the bottom wall (44) thereof, including radiopaque indicia (70) that identify an attribute of the assembly (10) after its implantation and clearly appear on an X-ray of the patient in a manner informing the radiologist or technologist and the medical practitioner of that particular attribute.

A dual reservoir access port includes a base having proximal and distal fluid reservoirs. The fluid reservoirs each comprise a bottom and a side wall. A dual prong outlet stem projects from a distal end of the base and comprises a first prong and a second prong. A first fluid channel extends through the first prong to the distal reservoir, and a second fluid channel extends through the second prong to the proximal fluid reservoir. A puncture shield is disposed between at least a portion of the second fluid channel and the bottom of the distal fluid reservoir. A needle-penetrable septum is disposed atop of each of the fluid reservoirs. A cap is placed over and around the port base compressing and sealing the septa against the base. A locking collar may be placed over a dual lumen catheter to lock the catheter to the dual prong outlet stem.
