Abstract

Described are implantable devices and methods for treating various disorders of the pelvic floor by delivering one or more drugs to a patient'"'"'s hypogastric nerve or branches or portions thereof, prostatic plexus nerve or branches or portions thereof, sacral splanchnic nerve or branches or portions thereof, pelvic splanchnic nerve or branches or portions thereof, prostate or branches or portions thereof, pelvic floor, colon or branches or portions thereof, bladder or portions thereof, vagina or portions thereof, anus or portions thereof, external anal sphincter or portions thereof, urethra or portions thereof, penile dorsal nerve or portions thereof, inferior rectal nerves or branches or portions thereof, perineal nerves or branches or portions thereof, scrotal nerves or branches or portions thereof, scrotum or portions thereof, Alcock'"'"'s Canal or branches or portions thereof, sacro-tuberous ligament or branches or portions thereof, ischial tuberosity or branches or portions thereof, greater sciatic foramen or branches or portions thereof, or lesser sciatic foramen or branches or portions thereof. One, two or more drug delivery regimes are provided on a continuous, alternating, intermittent or other basis to one or more selected nerves, nerve portions or tissues in an amount and manner effective to treat a number of disorders, including, but not limited to, urinary and/or fecal voiding dysfunctions such as constipation, incontinence disorders such as urge frequency and urinary retention disorders, sexual dysfunctions such as orgasmic and erectile dysfunction, pelvic pain, prostatitis, prostatalgia and prostatodynia.

implanting a first hermetically sealed implantable drug pump within the patient, the implantable drug pump configured to receive and house a volume of a first drug therewithin, and to deliver such first drug to a first exterior thereof via the first implantable drug catheter;

operably connecting a proximal end of the first drug catheter to the first implantable drug pump; and

delivering, from the first implantable drug pump, a first predetermined portion of the first drug housed therewithin to the exterior thereof through the first implantable drug catheter to the distal end thereof to the at least one of the hypogastric nerve or branches or portions thereof, prostatic plexus nerve or branches or portions thereof, sacral splanchnic nerve, pelvic splanchnic nerve or branches or portions thereof, prostate or branches or portions thereof, colon or branches or portions thereof, bladder or portions thereof, urethra or portions thereof, scrotal nerves or branches or portions thereof, scrotum or portions thereof, sacro-tuberous ligament or branches or portions thereof, ischial tuberosity or branches or portions thereof, greater sciatic foramen or branches or portions thereof, or lesser sciatic foramen or branches or portions thereof;

wherein the predetermined portion of the first drug is delivered in a configuration effective to provide at least partial relief from at least one of pelvic pain, prostatitis, prostatalgia, or prostatodynia.

2. The method of claim 1 further comprising:

implanting a distal end of a second implantable drug catheter in a second tissue volume adjacent, around or in at least one of the hypogastric nerve or branches or portions thereof, the prostatic plexus nerve or branches or portions thereof, the sacral splanchnic nerve or branches or portions thereof, the pelvic splanchnic nerve or branches or portions thereof, the prostate or branches or portions thereof, the colon or branches or portions thereof, the bladder or portions thereof, the urethra or portions thereof, the scrotal nerves or branches or portions thereof, the scrotum or portions thereof, the sacro-tuberous ligament or branches or portions thereof, the ischial tuberosity or branches or portions thereof, the greater sciatic foramen or branches or portions thereof, or the lesser sciatic foramen or branches or portions thereof;

implanting a second hermetically sealed implantable drug pump within the patient, the second implantable drug pump configured to receive and house a volume of a second drug therewithin, and to deliver such second drug to a second exterior thereof via the second implantable drug catheter;

operably connecting a proximal end of the second drug catheter to the second implantable drug pump; and

delivering, from the second implantable drug pump, a second predetermined portion of the second drug housed therewithin to the exterior thereof through the second implantable drug catheter to the distal end thereof to the at least one of the hypogastric nerve or branches or portions thereof, the prostatic plexus nerve or branches or portions thereof, the sacral splanchnic nerve or branches or portions thereof, the pelvic splanchnic nerve or branches or portions thereof, the prostate or branches or portions thereof, the colon or branches or portions thereof, the bladder or portions thereof, the urethra or portions thereof, the scrotal nerves or branches or portions thereof, the scrotum or portions thereof, the sacro-tuberous ligament or branches or portions thereof, the ischial tuberosity or branches or portions thereof, the greater sciatic foramen or branches or portions thereof, or the lesser sciatic foramen or branches or portions thereof;

wherein the combination of the predetermined portion of the first drug and the predetermined portion of the second drug is delivered in a configuration effective to provide at least partial relief from at least one of pelvic pain, prostatitis, prostatalgia, or prostatodynia.

3. The method of claim 2 wherein the first and second tissue volumes are located in respective ones of a right side and a left side of the patient.

4. The method of claim 1 further comprising:

implanting a distal end of a first implantable medical electrical lead in a second tissue volume of the patient adjacent, around or in at least one of the hypogastric nerve or branches or portions thereof, the prostatic plexus nerve or branches or portions thereof, the sacral splanchnic nerve or branches or portions thereof, the pelvic splanchnic nerve or branches or portions thereof, the prostate or branches or portions thereof, the colon or branches or portions thereof, the bladder or portions thereof, the urethra or portions thereof, the scrotal nerves or branches or portions thereof, the scrotum or portions thereof, the sacro-tuberous ligament or branches or portions thereof, the ischial tuberosity or branches or portions thereof, the greater sciatic foramen or branches or portions thereof, or the lesser sciatic foramen or branches or portions thereof, wherein the first lead comprises at least a first electrode;

operably connecting a proximal end of the first lead to an hermetically sealed implantable pulse generator configured to provide at least a first electrical stimulation pulse regime via at least the first lead;
