Publication number: 20090306606Abstract: A vascular access catheter having a catheter hub assembly and a catheter shaft having a plurality of lumens is disclosed. The hub assembly has a body with an interior cavity and an exterior surface with a plurality of openings that are configured to receive the catheter shaft and a plurality of extension tubes, which are fluidly connected to lumens of the catheter shaft. A vascular access port having a housing, at least one reservoir and a self-sealing septum having an outer surface, is positioned partially therein the interior cavity of the body. A portion of the housing defines a reservoir outlet stem that is in fluid communication with the reservoir. At least a portion of the outer surface of the septum is defined therein a port opening that is defined therein the body and is circumferentially surrounded by portions of the exterior surface of the hub body.Type: ApplicationFiled: June 10, 2008Publication date: December 10, 2009Applicant: AngioDynamics, IncInventors: Carol L.

Patent number: 7608065Abstract: A vascular access port is disclosed for subcutaneous implantation. The port is particularly adapted to be affixed to a bone to securely hold the port in position, to assist medical personnel in finding the port and to decrease a visibility of the port. The port has a chamber therein which is accessed by a needle through a septum adjacent the chamber. The chamber is placed into fluid communication with the vascular structure of the patient, such as through catheter tubing. The chamber is surrounded by a body with an outer surface which is preferably fitted with threads to facilitate secure but removable attachment of the port within a hole in the bone where the port is to be implanted.Type: GrantFiled: January 30, 2007Date of Patent: October 27, 2009Inventor: Bradley J. Glenn

Publication number: 20090204072Abstract: 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 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. In one embodiment, an identification feature is engraved or otherwise defined by the access port, so as to be visible after implantation via x-ray imaging technology.Type: ApplicationFiled: April 7, 2009Publication date: August 13, 2009Applicant: C.

Publication number: 20090156928Abstract: An implantable multi-lumen access port including indicators for ascertaining characteristics of the port is disclosed. In one embodiment, the access port comprises a housing that defines a first reservoir and a second reservoir. A first septum and second septum are respectively coupled with the housing to provide selective access to the first and second reservoirs. Each septum includes a plurality of protrusions defined about a periphery thereof that are palpable after implantation of the port in a patient to determine a relative position of the first septum with respect to the second septum. A radiographically observable indicator is also included on a base of the housing, so as to provide information relating to a characteristic of the dual-lumen port, such as suitability for power injection of fluids. The indicator in one embodiment includes a substantially rigid radiopaque component.Type: ApplicationFiled: November 7, 2008Publication date: June 18, 2009Applicant: C. R.
