  • Publication number: 20060217673
    Abstract: An implantable surgical injection port including a housing having a body, a closed distal end, a open proximal end and a fluid reservoir therebetween. The housing includes a needle penetrable septum attached to the housing about the opening. The injection port further includes at least one stabilizing element mounted to the housing for stabilizing the port within tissue. The stabilizing element is a member having an undeployed position and a deployed position. Wherein the element extends radially from the body in the deployed position.

  • Publication number: 20050277899
    Abstract: A method for implanting an injection port within a patient. The method involves providing a port having a housing with a closed distal end, a open proximal end, a fluid reservoir therebetween, a needle penetrable septum attached to the housing about the opening, and at least one attachment mechanism mounted to the housing at a pivot point along an outer periphery of the housing. The attachment mechanism is an arcuate hook pivotable with respect to the housing, the arcuate hook having a length extending substantially at least 180° about the pivot point. The method further involves placing the distal end of the port adjacent tissue, and rotating the arcuate hook at least 180 degrees so that a free end of the hook extends into tissue and back out again.

  • Publication number: 20050148956
    Abstract: An implantable surgical injection port having an undeployed position, and a deployed position wherein it is attached to tissue. The port includes a housing having a closed distal end, a open proximal end and a fluid reservoir therebetween. The port further includes a needle penetrable septum attached to the housing about the opening. The port even further includes at least one attachment mechanism mounted to the housing at a pivot point along an outer periphery of the housing. The attachment mechanism is an arcuate hook pivotable with respect to the housing, wherein the arcuate hook having a length extending substantially greater than 90° about the pivot point.

  • Publication number: 20050131383
    Abstract: In accordance with the present invention, there is provided a method for subcutaneously implanting an injection port for use with an implantable medical device. The method involves providing an injection port comprising an elongated flexible substantially non-rigid body having first and second ends and a wall therebetween, the wall is such that it will self seal after being punctured, the body further including and a fluid reservoir surrounded by the wall and a flexible elongated tubular catheter attached to the body which is in fluid communication with the reservoir. Thereafter, the method involves creating an incision within the patient, accessing the subcutaneous fat layer of the patient through the incision, creating a space in the subcutaneous fat layer and implanting the injection port within the subcutaneous fat layer such that the port can be found externally by palpitation.

  • Publication number: 20050131325
    Abstract: An injection port for subcutaneous placement within a body. The injection port includes an elongated flexible substantially non-rigid body having first and second ends and a wall therebetween. The wall is made from one or more materials such that it will self seal after being punctured by a needle. The body of the device further includs and a fluid reservoir surrounded by the wall. Lastly, the injection port includes a flexible elongated tubular catheter attached to the body which is in fluid communication with the reservoir.
