Claims (8)

  1. A penile implant (200), comprising: a first member (210) having a coupling portion (212) and a locking portion, the coupling portion (212) of the first member (210) including a sidewall (216) defining a spherical cavity (214), a second member (240) having a coupling portion (242) and a locking portion, the coupling portion (242) of the second member (240) having a spherical protrusion, the locking portion of the second member (240) including a projection extending from an end portion of the spherical protrusion, and a sheath defining a lumen, the lumen being configured to house the first member (210) and the second member (240); wherein the coupling portion (212) of the first member (210) is configured to engage the coupling portion (242) of the second member (240) to movably couple the first member (210) to the second member (240) such that the first member (210) is configured to be placed in a first position with respect to the second member (240) and a second position with respect to the second member (240), the locking portion of the first member (210) being configured to engage the locking portion of the second member (240) help retain the first member (210) in its second position with respect to the second member (240).
  2. The penile implant (200) of claim 1, wherein the coupling portion (212) of the first member (210) is configured to receive the coupling portion (242) of the second member (240).
  3. The penile implant (200) of claim 1, wherein the coupling portion (212) of the first member (210) includes a cavity, the locking portion of the first member (210) being disposed within the cavity.
  4. The penile implant (200) of claim 1, wherein the locking portion of the first member (210) is a groove defined by the side wall.
  5. The penile implant (200) of claim 1, the coupling portion (242) of the second member (240) is a first coupling portion of the second member (240), wherein the second member (240) includes a second coupling portion, the first coupling portion of the second member (240) including a protrusion portion, the second coupling portion of the second member (240) including a side wall defining a cavity.
  6. The penile implant (200) of claim 1, wherein the coupling portion (212) of the first member (210) includes a cavity, the locking portion of the first member (210) includes a projection, the projection being disposed within the cavity.
  7. The penile implant (200) of claim 1, wherein the coupling portion (242) of the second member (240) includes a protrusion portion, the locking portion of the second member (240) including a groove defined on the protrusion portion.
  8. The penile implant (200) of any of claims 1-7, further comprising: a first end cap coupled to the first member (210); a second end cap coupled to the second member (240); and the lumen being configured to house at least a portion of the first end cap, and at least a portion of the second end cap.

Description

TECHNICAL FIELD This disclosure relates generally to bodily implants and more specifically to bodily implants, such as penile prostheses, that may be placed in multiple configurations. BACKGROUND One treatment for male erectile dysfunction is the implantation of a penile prosthesis that may be placed in a multiple configurations. For example, some existing penile prostheses may be implanted in or near the penis of the patient and may be disposed in a first configuration to place the penis in a flaccid-like state and may be disposed in a second configuration to place the penis in an erect-like state. Some existing implants include complex activation mechanisms to change the configurations of the implants and may require a large amount of effort to change or convert the implant from one configuration to another configuration. Accordingly, it would be useful to provide a bodily implant, such as a penile prosthesis that may efficiently be moved from one configuration to another configuration. Exemplary penile prostheses are known from US 4,619,251 and US 2008/0103353 A1. US 4,619,251 discloses a bistable penile prosthesis designed to be surgically implanted in the penis for the treatment of erectile impotence. The prosthesis includes an articulated column enclosed within an outer elongated sheath. The articulated column has segments including interlocking means for reducing radial slippage between the facing ends of adjacent ones of the segments whereby the likelihood of the segments becoming disjointed is reduced. US 2008/0103353 A1 discloses a prosthetic device comprising stacked column segments. A first one of the column segments comprises a ball surface facing along a column axis. The ball surface has a generally convex shape that is articulable in a mating socket of a second one of the column segments. The first one of the column segments comprises a socket surface facing an opposite direction along the column axis. The socket surface has a generally concave shape that is articulable on a mating ball of a third one of the column segments. Multiple column segments similar to the first column segment are stacked to form the column. SUMMARY The present invention is defined by the appended claims. According to an aspect, a penile implant includes a first member having a coupling portion and a locking portion and a second member having a coupling portion and a locking portion The coupling portion of the first member is configured to engage the coupling portion of the second member to movably couple the first member to the second member such that the first member is configured to be placed in a first position with respect to the second member and a second position with respect to the second member. The locking portion of the first member is configured to engage the locking portion of the second member help retain the first member in its second position with respect to the second member. In some embodiments, the coupling portion of the first member includes a cavity portion configured to receive the coupling portion of the second member. In some embodiments, the coupling portion of the first member includes a cavity portion, the coupling portion of the second member includes a protrusion portion, the cavity portion is configured to receive at least a portion of the protrusion portion. In some embodiments, the coupling portion of the first member includes a cavity having a rounded surface. In some embodiments, the coupling portion of the second member includes a protrusion portion, the protrusion portion having a rounded surface. In some embodiments, the coupling portion of the first member includes a cavity, the locking portion of the first member being disposed within the cavity. According to the present invention, the coupling portion of the first member includes a side wall defining a cavity. In some embodiments, the locking portion of the first member is a groove defined by the side wall. In some embodiments, the coupling portion of the second member includes a protrusion portion, the locking portion of the second member being disposed on the protrusion portion. In some embodiments, the coupling portion of the second member includes a protrusion portion, the locking portion of the second member includes a ridge, the ridge being disposed on the protrusion portion. In some embodiments, the coupling portion of the second member includes a protrusion portion, the locking portion of the second member includes a projection disposed on the protrusion portion. In some embodiments, the coupling portion of the second member is a first coupling portion of the second member, wherein the second member includes a second coupling portion, the first coupling portion of the second member including a protrusion portion, the second coupling portion of the second member including a side wall defining a cavity. In some embodiments, the coupling portion of the first member includes a cavity, the locking portion of the first member
