Let's study ID: the concept of irreducible complexity (Introduction)

It simply means an organ must have all its specific integrated parts. It must be seen as stand alone, as illustrated by a mouse trap performing without any help or integration with other organs:

"Conventionally, renal assistance devices (RADs) are extracorporeal artificial systems that rely on a combination of a conventional hemofilter and a bioreactor. They mimic glomerular filtration and drive essential metabolic, endocrinologic, and immunologic kidney functions. Researchers creating artificial organ devices are preclinically investigating methods to miniaturize and implant RADs. In addition to RADs, scientists develop renal scaffolds for bioartificial kidneys from pig kidneys, discarded human kidneys, or polymers such as collagen, hyaluronic acid, alginate, agarose, chitosan, fibrin, and gelatin.

"Similarly, artificial livers may be a solution to organ donor shortages for treating end-stage liver failure and an alternative to extracorporeal artificial supports.8 For example, researchers made artificial “liver-buds” from human induced pluripotent stem cells (iPSCs) in vitro and transplanted them to successfully rescue an animal model of liver failure.

"Scientists and clinicians can use 3D printing for cardiac surgical planning and creating custom-fit implants. Researchers have also created devices for cardiac tissue maturation that enhance implant viability, such as cardiac-specific extracellular matrices made of animal-derived bioink or decellularized cardiac tissue. Additionally, in proof-of-concept studies, researchers have manufactured cardiac structures such as branched coronary arteries and embryonic hearts with hydrogels. Using computed tomography (CT) and magnetic resonance imaging (MRI) data, they printed hydrated materials such as alginate, collagen, and fibrin to build mechanically robust and complex 3D anatomical cardiac architectures."

Comment: the research to invent implantable artificial organs follows the concept of plug and play. Both kidney and liver need a supply of blood to work to full capacity and an emptying system for the discharge. A heart just needs a blood volume to work with. The artificial organs will be just as IC as the natural ones. Why must you try to reinterpret what is presented to fit your preconceived desires? IC demands ID. The primary premise of ID.
