Generally described herein are apparatus, systems and methods related to a mechanical interlock joint geometry for various components and joining of components thereby creating a reliable seal against fluid leaks that is resistant at typical pressures experienced when the components are implanted into a human body. Furthermore, the seal may be enhanced when a fluid pressure exerted inside the components is increased (e.g., from 1 to 10 psi).

The gastric banding system of claim 10 wherein the second interlock fluidly couples the first tube and the fluid reservoir and comprises a second male half and a second female half, the second male half having a second ring and a second flange, the second female half defining a second groove for receiving the second ring, and further defining a second annular wall for sealing with the second flange. 12. The gastric banding system of claim 11 further comprising a third interlock and a second sleeve, wherein the second tube is connected to the fluid reservoir via the third interlock and the second sleeve is overmolded on the third interlock, a portion of the second tube and a portion of the fluid reservoir. 13. The gastric banding system of claim 12 wherein the third interlock fluidly couples the second tube and the fluid reservoir and comprises a third male half and a third female half, the third male half having a third ring and a third flange, the third female half of the third interlock defining a third groove for receiving the third ring, and further defining a third annular wall for sealing with the third flange. 14. The gastric banding system of claim 1, wherein the first circumferential groove is defined by a first sidewall and a second sidewall facing the first sidewall, and wherein when the first male half and the first female half are interlocked, the first ring extends into the groove and the first sidewall is adjacent to the first side of the ring and the second sidewall is adjacent to the second side of the ring. 15. A fluid reservoir for carrying fluid within a gastric banding system for the treatment of obesity, the fluid reservoir comprising: a first half of the fluid reservoir of unitary construction including: a first connector for fluidly connecting the fluid reservoir to an inflatable portion of a gastric band,a first housing coupled to the connector, the first housing defining a first sub-reservoir, the first housing extending to a first flat joining surface, anda ring and flange coupled to the first flat joining surface, the ring and flange defining a second sub-reservoir, the ring spaced between the first flat joining surface and the flange, the ring having a first side that faces the flange and having a second side opposite the first side that faces the first flat joining surface; anda second half of the fluid reservoir including: a second connector for fluidly connecting the fluid reservoir to an access port, anda second housing coupled to the second connector, the second housing defining a third sub-reservoir, the second housing tapering to a second flat joining surface, the second housing further defining a circumferential groove for receiving the ring and for surrounding the first and second sides of the ring and defining an annular wall facing a direction opposite the second flat joining surface that seals with the flange,wherein when the ring extends into and is surrounded by the groove, and when the annular wall seals with the flange, physical interference between the ring and the groove and between the flange and the annular wall cause the first half and the second half to form a first interlock therebetween. 16.
