The penile prosthesis includes a reservoir, wherein the reservoir is fluidically connected to the pump. The penile prosthesis includes an inflatable cylinder, wherein the inflatable cylinder is fluidically connected to the pump through a length-adjustable tube. The length-adjustable tube allows adjustment of a length of the length-adjustable tube according to a patient's unique anatomy. ## Claims ### Claim 1 A penile prosthesis, comprising a pump; a reservoir fluidically connected to the pump; at least one inflatable cylinder configured to inflate in response to actuation of the pump by a user to transfer fluid from the reservoir into the at least one inflatable cylinder; at least one length-adjustable tube fluidically connecting the pump to the at least one inflatable cylinder and configured to be adjustable in length according to a patient's unique anatomy, and a nut coupling the at least one length-adjustable tube to the pump, where the nut is configured to be loosened to allow the at least one length-adjustable tube to be passed through the nut and away the pump to extend a length of the at least one length-adjustable tube and to be passed through the nut and toward the pump to reduce the length of the at least one length-adjustable tube. ### Claim 2 (depends on 1) The penile prosthesis of claim 1, wherein the at least one length-adjustable tube includes a longitudinally extending accordion-like structure configured to extend in length in response to an extension force applied to the longitudinally extending accordion-like structure. ### Claim 3 (depends on 2) The prosthesis of claim 2, wherein the penile prosthesis includes a first inflatable cylinder and a second inflatable cylinder, and the longitudinally extending accordion-like structure includes two ends, with one of the two ends attached to the pump and another of the two ends attached to the first inflatable cylinder, and the accordion-like structure is configured to extend in length by pulling the two ends away from each other. ### Claim 4 (depends on 3) The prosthesis of claim 3, wherein the longitudinally extending accordion-like is configured to be reduced in length by pushing the two ends of the longitudinally extending accordion-like structure longitudinally toward each other. ### Claim 5 (depends on 2) The prosthesis of claim 2, wherein the longitudinally extending accordion-like structure is configured to be shortened in length in response to a longitudinal contraction force applied to the longitudinally extending accordion-like structure. ### Claim 6 (depends on 1) The penile prosthesis of claim 1, wherein, when the nut is loosened, the at least one length-adjustable tube is adapted to be pulled out from the pump to extend a length of the at least one length-adjustable tube and further adapted to be pushed back into the pump to reduce the length of the at least one length-adjustable tube. ### Claim 7 (depends on 1) The penile prosthesis of claim 1, wherein the reservoir is fluidically connected to the pump through a second length-adjustable tube that is configured to be adjustable in length according to the patient's unique anatomy. ### Claim 8 (depends on 7) The penile prosthesis of claim 7, wherein the second length-adjustable tube is fluidically connected to the pump through a connector and a flexible tube. ### Claim 9 (depends on 8) The penile prosthesis of claim 8, wherein the connector connects the flexible tube to the length-adjustable tube. ### Claim 10 (depends on 9) The penile prosthesis of claim 9, wherein the connector includes a male connector portion attachable to a female connector portion, and wherein the male connector portion includes a plurality of protrusions and the female connector portion includes a plurality of openings, with the plurality of openings of the female connector portion sized to receive the plurality of protrusions of the male connector portion. ### Claim 11 (depends on 10) The penile prosthesis of claim 10, wherein the female connector portion includes a tube that is insertable into a lumen of the male connector portion. ### Claim 12 (depends on 1) The penile prosthesis of claim 1, wherein the at least one inflatable cylinder includes a first inflatable cylinder and a second inflatable cylinder, and the penile prosthesis includes a first length-adjustable tube attachable between the first inflatable cylinder and the pump and a second length-adjustable tube attachable between the second inflatable cylinder and the pump. ### Claim 13 (depends on 12) The penile prosthesis of claim 12, wherein the first length-adjustable tube and the second length-adjustable tube are configured to be adjusted separately according to the unique anatomy of the patient. ### Claim 14 (depends on 1) The penile prosthesis of claim 1, further comprising a valve assembly arranged within the pump and configured to release fluid in the at least one inflatable cylinder back into the reservoir to deflate at least one inflatable cylinder. ### Claim 15 (depends on 14) The penile prosthesis of claim 14, further comprising a nut configured to facilitate adjustment of the at least one length-adjustable tube, and the nut is removably secured to the valve assembly.
