Method of implanting a fluid injection port

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.

Description

FIELD OF THE INVENTION [0001] The present invention has application in conventional endoscopic and open surgical instrumentation as well as application in robotic-assisted surgery. The present invention has even further relation to adjustable surgically implantable bands, such as gastric bands for the treatment of obesity. BACKGROUND OF THE INVENTION [0002] The percentage of the world's population suffering from morbid obesity is steadily increasing. Severely obese persons are susceptible to increased risk of heart disease, stroke, diabetes, pulmonary disease, and accidents. Because of the effect of morbid obesity to the life of the patient, methods of treating morbid obesity are being researched. [0003] Numerous non-operative therapies for morbid obesity have been tried with virtually no permanent success. Dietary counseling, behavior modification, wiring a patient's jaws shut, and pharmacological methods have all been tried, and failed to correct the condition. Mechanical apparatu...

Problems solved by technology

Severely obese persons are susceptible to increased risk of heart disease, stroke, diabetes, pulmonary disease, and accidents.

Numerous non-operative therapies for morbid obesity have been tried with virtually no permanent success.

Dietary counseling, behavior modification, wiring a patient's jaws shut, and pharmacological methods have all been tried, and failed to correct the condition.

Such devices cannot be employed over a long term, however, as they often cause severe irritation, necessitating their periodic removal and hence interruption of treatment.

There are many disadvantages to the above procedure.

Current minimally invasive techniques are difficult for surgeons to master, and have many additional drawbacks.

Also, there is a high level of patient uneasiness with the idea of such a drastic procedure which is not easily reversible.

In addition, all malabsorption techniques carry ongoing risks and side effects to the patient, including malnutrition and dumping syndrome.
