Penile erection assist device and method
First Claim
1. A method for treating male impotence, comprising the steps of:
- positioning a section of thin sterile tubing within a patient such that a distal end is disposed at a location which is adjacent or contacting erectile penile tissue;
implanting a drug delivery device remote from the penis of a patient such that the drug delivery device is in fluid communication with the thin sterile tubing defining a first delivery pathway therebetween;
inserting a predetermined dosage of a vasodilating material into said drug delivery device; and
delivering the predetermined vasodilating material through the thin tubing to the penile erectile tissue to stimulate an erection therein.

Abstract
A penile erection assist method and apparatus treats male impotence by providing physiologically active vasodilating drugs to the penile erectile tissues in a manner which minimizes pain therein. The penile erection assist device includes an implantable storage unit which is implanted remote from sensitive penile tissue. The drug is delivered to the penile erectile tissue through sterile thin tubing which is implanted into the patients body with the proximal end in fluid communication with the storage unit and the distal end configured to be positioned adjacent proximal penile erectile tissues. This configuration advantageously preserves the intact function of penile erectile tissues by minimally intruding therein. Further, the device and method can be employed with patients having various etiologic origins whether the need is acute or permanent, according to the needs of the patient.

7. A method for treating male impotence, comprising the steps of:
-
implanting a drug delivery device remote from the penis of a patient; inserting a predetermined amount of vasodilating material into said drug delivery device; forming at least one drug delivery pathway having a proximal end and a distal end, said pathway being disposed internal to the patient such that a proximal end of said pathway is in fluid communication with said fluid delivery device, and a distal end is disposed adjacent erectile penile tissue, wherein said drug delivery device delivers vasodilating material to erectile penile tisse to dilate penile vasculature thereby to result in penile erection. - View Dependent Claims (8, 9, 10)

11. A penile erection assist device for treating patients with impotence, comprising:
-
an implantable storage unit for storing physiologically active vasodilating material, said storage unit including an inlet configured to be accessible from outside the patient'"'"'s body without surgery, said storage unit comprising a housing and a flexible diaphragm container sealed to and positioned within said housing to define a storage chamber for a vasodilating material; fluid delivery means operatively associated with said storage unit; at least one implantable thin sterile tubing hose in fluid communication with said storage unit and said fluid delivery means and having a proximal and distal end providing at least one delivery pathway, wherein said distal end is configured to be positioned adjacent penile erection tissue for delivering the vasodilating material thereto; a control unit operatively associated with said fluid delivery means for controlling the delivery of said vasodilating material stored in said storage unit, said control unit including a plurality of sensors for detecting and monitoring operational parameters of said device, wherein at least one of said plurality of sensors is operatively associated with said fluid delivery means and at least one of said plurality of sensors is operatively associated with said storage unit;
said plurality of sensors including a plurality of pressure sensors which detect a plurality of operating parameters, wherein a first pressure sensor is positioned in said housing to detect the pressure of the drug in said diaphragm container, thereby indicating the amount of drug available therein, wherein a second pressure sensor is positioned adjacent the proximal end of said thin tubing hose to detect and thereby monitor the pressure of the drug as it is discharged from said storage container, wherein a third pressure sensor is positioned to detect the pressure of the drug taken into said fluid delivery means, and wherein a fourth pressure sensor is positioned to detect the pressure of the drug discharge from said distal end of said tubing and thereby delivered to the penile erectile tissues; anda user interface unit positioned remote from said storage unit operatively associated with said control unit and accessible by a patient to allow adjustment or activation of said device and for providing input/output communications therebetween. - View Dependent Claims (12, 13, 14, 15, 16, 17)
