Dual reservoir implantable access port

a technology of implantable access port and reservoir, which is applied in the field of medical devices, can solve the problems of increasing the geometric footprint of the access port, invasive apheresis treatment is typically administered frequently, and the incision size of the access port is increased, so as to reduce the overall size and geometric footprint of the implantable access port device, and reduce the size of the incision required to insert the device into the patien

Benefits of technology

[0010]According to various embodiments of the present invention, the D-shaped fluid reservoirs are axially aligned such that the space between the reservoirs is reduced, thereby reducing the overall size and geometric footprint of the implantable access port device. Thus, the size of the incision required to insert the device into a patient can be reduced.

Problems solved by technology

Invasive apheresis treatments typically are administered frequently and can be painful as a result of the multiple venous punctures to the patient's skin.
This arrangement, however, leads to an increase in size of the geometric footprint of the access port because of the space created between the two circular reservoirs.

Abstract

An implantable access port for use in transferring fluid transdermally between an external fluid storage or dispensing device and a site within a patient is disclosed. The access port includes a body, at least two reservoirs defined within the access port body, and at least one septum secured to the body and enclosing the reservoirs within the body. The access port also includes reservoir outlets defined within the reservoirs. The access port also has body conduits defined within the body and in fluid communication with the reservoir outlets and external openings defined in the exterior of the body. An implantable access port and system for use in apheresis is also provided that includes an implantable access port, at least one needle, and a catheter that is fluidly connected to the access port.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to Provisional Patent Application Ser. No. 60 / 977,736, which was filed on Oct. 5, 2007, Provisional Patent Application Ser. No. 61 / 044,752, which was filed on Apr. 14, 2008, and Provisional Patent Application Ser. No. 61 / 056,920, filed May 29, 2008, which applications are incorporated in their entirety in this document by reference.FIELD OF THE INVENTION[0002]The invention relates in general to medical devices. More particularly, the invention relates to a dual reservoir implantable access port for use in accessing either the vasculature or a selected treatment site within the body of a patient.BACKGROUND OF THE INVENTION[0003]The use of implantable access ports in the art of drug therapy is well known, in which an access port is implanted beneath the subcutaneous layers of a patient's skin. The known access ports are constructed to provide for repeated access to the vascular system of a patient, or a sele...
