Radiopaque and septum-based indicators for a multi-lumen implantable port
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.
Low-Profile Single and Dual Vascular Access Device
A low-profile access port for subcutaneous implantation within a patient is disclosed. The access port includes a receiving cup that provides a relatively large subcutaneous target to enable catheter-bearing needle access to the port without difficulty. In one embodiment, a low-profile access port comprises a body including a conduit with an inlet port at a proximal end, and a receiving cup. The receiving cup is funnel shaped to direct a catheter-bearing needle into the conduit via the inlet port. The conduit is defined by the body and extends from the inlet port to an outlet defined by a stem. A bend in the conduit enables catheter advancement past the bend while preventing needle advancement. A valve/seal assembly is also disposed in the conduit and enables passage of the catheter therethrough while preventing fluid backflow. The body includes radiopaque indicia configured to enable identification of the access port via x-ray imaging.

IMPLANTABLE MEDICAL DEVICE FOR IMPROVED PLACEMENT AND ADHERENCE IN THE BODY
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.
Implantable access port including a sandwiched radiopaque insert
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.
Systems and Methods for Radiographically Identifying an Access Port
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.
Systems and Methods for Radiographically Identifying an Access Port
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. The radiopaque identification feature can have a thickness protruding from the outer surface of the power-injectable access port base such that it is perceivable by sight and touch prior to subcutaneous implantation of the power injectable access port.
Implantable vascular access port with dual, high-flow trans-chamber and low-flow, access, and needle lock for high-flow
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.
Systems and methods for radiographically identifying an access port
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.
