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.

Claims

1. A method for implanting an injection port within a patient, said method comprising:

a. providing a port comprising a housing having a closed distal end, a open proximal end, a fluid reservoir therebetween, a needle penetrable septum attached to said housing about said opening, and at least one attachment mechanism mounted to said housing at a pivot point along an outer periphery of said housing, said attachment mechanism comprising an arcuate hook pivotable with respect to said housing, said arcuate hook having a length extending substantially at least 180°

about said pivot point;

b. placing said distal end of said port adjacent tissue; and

c. rotating said arcuate hook at least 180 degrees so that a free end of said hook extends into tissue and back out again.

2. The method of claim 1 further comprising the step of attaching said port to a catheter tube.

3. The method of claim 2 further comprising the step of adding fluid to said port.

4. The method of claim 2 further comprising the step of withdrawing fluid from said port.

5. A method for implanting an injection port within a patient, said method comprising:

a. providing a port comprising a housing having a closed distal end, a open proximal end, a fluid reservoir therebetween, a needle penetrable septum attached to said housing about said opening, and at least one attachment mechanism mounted to said housing at a pivot point along an outer periphery of said housing, said attachment mechanism comprising an arcuate hook pivotable with respect to said housing, said arcuate hook having a length extending substantially at least 180°

about said pivot point;

b. placing said distal end of said port adjacent tissue;

c. rotating said arcuate hook at least 180 degrees so that a free end of said hook extends into tissue and back out again; and

d. connecting said port to an adjustable gastric band via a catheter tube.

6. The method of claim 5 further comprising the step of adding fluid to said port.

7. The method of claim 5 further comprising the step of withdrawing fluid from said port.
