Catheter apparatus for delivering drugs to the penis
First Claim
1. An implantable catheter apparatus for self-administration of drugs to the penis of a human patient comprisinga catheter havinga flexible wall surrounding a lumen,a distal portion adapted to be placed within the corpus cavernosum of the penis of a human patient, said distal portion having a closed distal end,a proximal portion adapted to be implanted in the body of said patient at a location remote from said penis, said proximal portion having a proximal end, andan intermediate portion connecting said proximal and said distal portions and adapted to be implanted within the body of said patient, andresealable injection port means located at said proximal end providing fluid access from a source of fluid to said lumen,said distal portion of said catheter having a plurality of longitudinal slits piercing said wall of said catheter, said slits being at different distances from said distal end of said catheter such that adjacent slits have an overlapping staggered configuration.

Abstract
An implantable catheter apparatus for self-administration of drugs to the penis of a human patient comprises
an elongated catheter having a flexible wall surrounding a lumen
the catheter having
a distal portion having a closed distal end and adapted to be placed within the corpus cavernosum of the penis of a human patient,
a proximal portion adapted to be implanted in the body of the patient at a location remote from the penis, and
an intermediate portion connecting the proximal and distal portions and adapted to be implanted within the body of said patient,
resealable injection port means located at the proximal end providing fluid access from a source of fluid to the lumen,
the distal portion of the catheter being provided with longitudinal slits to permit fluid to flow from the lumen to the exterior of said catheter.
In one embodiment of the invention the slits are staggered longitudinally along the wall of the catheter at different distances from the closed end with longitudinal overlap, while in another embodiment the catheter is provided with a sheath surrounding the wall and covering the slits.
