Abstract

According to an aspect, an implant includes a sheath defining a lumen, a cable member disposed within the lumen defined by the sheath, and a tensioner. The tensioner is configured to engage the cable to apply tension to the sheath.

First claim

What is claimed is:

1. A medical implant ( 100 , 200 ), for example a penis implant, comprising:
a sheath ( 110 , 210 ) defining a lumen ( 222 );
which sheath ( 110 , 210 ) further defines a window or opening ( 211 , 213 ) in the sheath ( 110 , 210 )
a cable member ( 130 , 230 ) disposed within the lumen of the sheath ( 110 , 210 ); and
a tensioner ( 150 , 250 ) engaged with the cable member ( 130 , 230 ) for applying tension to the sheath ( 110 , 210 ) so that the sheath ( 110 , 210 ) is selectively arrangeable between a first tensioned configuration and second non-tensioned configuration,
wherein the tensioner ( 150 , 250 ) comprises a bias member ( 254 ), for providing a bias to the tensioner ( 150 , 250 ),
wherein the tensioner ( 150 , 250 ) comprises a release member ( 258 , 260 ), the release member ( 258 , 260 ) being moveable between a tension retention position, wherein tension is retained in the sheath ( 110 , 210 ), and a tension release position, wherein tension is released from the sheath ( 110 , 210 ),
wherein the release member ( 258 , 260 ) is accessible and operable through the window or opening ( 211 , 213 ) in the sheath ( 110 , 210 ), whereby a portion of the release member ( 258 , 260 ) is extendible through the window or opening ( 211 , 213 ) in the sheath ( 110 , 210 ).

2. The implant ( 100 , 200 ) according to claim 1 , wherein in the first tensioned configuration, the sheath ( 110 , 210 ) has a linear configuration and in the second non-tensioned configuration, the sheath ( 110 , 210 ) has a curved configuration, and/or wherein the cable member ( 130 , 230 ) is coupled to the sheath ( 110 , 210 ) at a first end portion ( 218 ) of the sheath ( 110 , 210 ) and at a second end portion ( 220 ) of the sheath ( 110 , 210 ), preferably wherein the cable member ( 130 , 230 ) is coupled to the first end portion ( 218 ) of the sheath ( 210 ) via a first crimp member ( 224 ), and to the second end portion ( 220 ) of the sheath ( 210 ) via a second crimp member ( 226 ).

3. The implant ( 100 , 200 ) according to claim 1 , wherein the bias member ( 254 ) provides a bias to the tensioner ( 150 , 250 ) such that tension is removed from the sheath ( 110 , 210 ), and the sheath ( 110 , 210 ) assumes the second, non-tensioned configuration, preferably wherein the bias member ( 254 ) is a spring element.

4. The implant ( 100 , 200 ) according to claim 1 , wherein the release member ( 258 , 260 ) is pivotably movable between the tension retention and release positions, with respect to the sheath ( 110 , 210 ).

5. The implant ( 100 , 200 ) according to claim 1 , wherein the tensioner ( 150 , 250 ) includes a plunger member ( 252 ) and a plunger guide ( 256 ) separated by the bias member ( 254 ), wherein the cable member ( 130 , 230 ) extends through the plunger member ( 252 ), the bias member ( 254 ) and the plunger guide ( 256 ).

6. The implant ( 100 , 200 ) according to claim 5 , wherein in the first tensioned configuration of the sheath ( 110 , 210 ), an engagement portion ( 262 ) of the release member ( 260 , 258 ) engages the plunger member ( 252 ).

7. The implant ( 100 , 200 ) according to claim 6 , wherein in the second non-tensioned configuration of the sheath ( 110 , 210 ), the engagement portion ( 262 ) of the release member ( 260 , 258 ) is disengaged from the plunger member ( 252 ).

8. The implant ( 100 , 200 ) according to claim 5 , wherein the release member ( 260 , 258 ) includes an activation portion ( 264 ), for moving the release member ( 260 ) for disengaging the plunging member ( 252 ) from the engagement portion ( 262 ) of the release member ( 260 ), whereby the plunger member ( 252 ) is movable by the bias member ( 254 ) so that the sheath ( 110 , 210 ) assumes the second configuration.

9. The implant ( 100 , 200 ) according to claim 1 , wherein the sheath ( 110 , 210 ) defines a plurality of slots ( 214 ) arranged at slot locations in a sidewall ( 212 ) of the sheath ( 110 , 210 ), which slots ( 214 ) facilitate flexibility of the sheath ( 110 , 210 ), at the slot locations, preferably wherein the slots ( 214 ) are non-linear or linear, and/or preferably wherein the slots ( 214 ) define a pattern of openings, preferably wherein the slots ( 214 ) 5 are configured to engage each other and lock into place, so that columnar strength of the sheath ( 110 , 210 ), is increased when the sheath ( 110 , 210 ), is in the first configuration.

10. The implant ( 100 , 200 ) according to claim 1 , further comprising a 10 centering member ( 233 ) disposed between the cable member ( 130 , 230 ) and the sheath ( 110 , 210 ), for centering the cable member ( 130 , 230 ) in the sheath, preferably wherein the cable member ( 130 , 230 ) is disposed within a lumen of the centering member ( 233 ).

11. The implant ( 100 , 200 ) according to claim 1 , further comprising an end cap ( 282 ) coupled to the first end portion ( 218 ) of the sheath ( 110 , 210 ) and a front tip base ( 284 ) and a front tip ( 286 ) coupled to the second end portion ( 220 ) of the sheath ( 110 , 210 ).

12. The implant ( 100 , 200 ) according to claim 1 , wherein the cable element ( 130 , 230 ) is configured to move within the sheath ( 110 , 210 ) when moved between the tensioned and non-tensioned configurations.

13. Method for arranging the implant ( 100 , 200 ) according to claim 1 , between a first, tensioned configuration and a second, non-tensioned configuration, comprising the steps of placing the implant ( 100 , 200 ) in the first tensioned configuration, in which tensioned configuration the release member ( 258 , 260 ), protrudes through the window or opening ( 211 , 213 ) in the sheath ( 110 , 210 ), and subsequently releasing the tension from the implant ( 100 , 200 ) to place the implant ( 100 , 200 ) in the second non-tensioned configuration, by way of pressing the release members ( 258 , 260 ) so that these no longer protrude through the window or opening 30 ( 211 , 213 ) in the sheath ( 110 , 210 ).

14. Method according to claim 13 , whereby placing the implant ( 100 , 200 ) in the first tensioned configuration comprises lifting or straightening the implant ( 100 , 200 ), whereby the plunger member ( 252 ) moves towards the first end portion ( 218 ) of the sheath ( 110 , 210 ) against the bias of the bias member ( 254 ), whereby the release members ( 258 , 260 ) engage the plunger member ( 252 ), whereby tension is applied to the sheath ( 110 , 210 ) via the cable ( 130 , 230 ).

15. Method according to claim 13 , wherein the implant ( 100 , 200 ) is placed in the second, non-tensioned configuration by pressing on the release members ( 258 , 260 ) so that these disengage the plunger member ( 252 ), whereby the bias member ( 254 ) forces the plunger member ( 252 ) towards the second end portion ( 220 ) of the sheath ( 110 , 210 ), whereby tension in the sheath ( 110 , 210 ) is removed.
