A method of implanting a penile prosthesis includes providing a tool including a needle having a locking groove formed in a shaft of the needle, where the locking groove has a ridge or a notch. The method includes accessing a penile implant having a length of suture coupled to a distal end of the penile implant, securing the length of suture into the locking groove of the needle； inserting the tool and the needle into a corpora cavernosum of a penis； passing the needle and the length of suture through a glans of the penis； disengaging the length of suture from the locking groove of the needle； and pulling the penile implant into the corpora cavernosum of the penis with the length of suture.
