Abstract
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.
Claims23
An implantable port for providing vascular access, and which is supported by a bone, comprising in combination:
- a chamber;
- said chamber adapted to be placed into fluid communication with a vascular structure;
- a septum;
- said septum located adjacent at least one side of said chamber;
- said septum adapted to be penetrated by a needle and reseal after the needle is removed;
- a collar surrounding said septum;
- said collar adapted to hold said septum adjacent said chamber;
- and
- a bone engagement surface on said collar, said bone engagement surface adapted to be coupled to a bone to which the port is to be supported.
An implantable access port comprising in combination:
- a body having a chamber therein;
- an aperture in said body, said aperture adapted to provide access into said chamber for a needle;
- a septum between said aperture and said chamber;
- said chamber adapted to be coupled to a vascular structure with fluid communication between said chamber and the vascular structure;
- and
- said body adapted to be affixed to a bone, such that said port is held in fixed position relative to said bone.
A method for fixing a subcutaneous vascular access port at an implantation site, including the steps of:
- providing an implantable access port having a body having a chamber therein;
- an aperture in the body, the aperture adapted to provide access into the chamber for a needle;
- a septum between the aperture and the chamber;
- and the chamber adapted to be coupled to a vascular structure with fluid communication between the chamber and the vascular structure;
- attaching the port to a bone at the implantation site;
- and
- coupling the chamber to a vascular structure with fluid communication therebetween.
