Implantable bioartificial perfusion system
09814829 · 2017-11-14 ·

The disclosure provides an implantable bioartificial active secretion system for providing a physiological regulating secretion such as insulin necessary for functionality of a physiologic activity such as glucose metabolism of a living-being host. The system includes a housing implantable within the host, in fluidic communication with tissue fluid indicative of a physiological regulating secretion need. A chamber within the housing contains a plurality of physiologically active, autonomously functioning, live secretory cells for producing the physiological regulating secretion. A continually operating two pump apparatus moves tissue fluid into contact with the secretory cells for pick up of the physiological regulating secretion for subsequent physiologically-effective dispensing into the host, while avoiding immuno-rejection of the host body or of the host to the secretory cells.

Biomimetically Designed Modular Microfluidic-Based Capillaries & Lymphatic Units for Kidney & Liver Dialysis Systems, Organ Bio-Reactors and Bio-Artificial Organ Support Systems
20170252701 · 2017-09-07 ·

A technology that provides various modular biomimetic microfluidic modules emulating varieties of microvasculature in body. These microfluidic-base capillaries and lymphatic Technology modules are constructed as multilayered-microfluidic microchannels of various shapes, and aspect ratios using diverse biocompatible microfluidic polymers. Then, various semipermeable membranes are sandwiched in between these multilayered microfluidic microchannels. These membranes have different chemical, physical characteristics and MWCO values. Consequently, this design will produce much smaller dimension channels similar to human vasculature to achieve biomimetic properties like of human organs and tissues. By interchanging microfluidic-layers or the membranes various diverse modules are designed that act as building blocks for constructing various medical devices, various forms of dialysis devices including albumin and lipid dialysis, water purification, bioreactors, bio-artificial organ support systems. Connecting various modules in diverse combinations, permutations, in parallel and/or in series to ultimately design many unrelated medical devices such as dialysis, bioreactors and organ support devices.

CELL ENCAPSULATION DEVICES WITH CONTROLLED OXYGEN DIFFUSION DISTANCES

Cell encapsulation devices for biological entities and/or cell populations that contain at least one biocompatible membrane composite are provided. The cell encapsulation devices mitigate or tailor the foreign body response from a host such that sufficient blood vessels are able to form at a cell impermeable surface. Additionally, the encapsulation devices have an oxygen diffusion distance that is sufficient for the survival of the encapsulated cells so that the cells are able to secrete a therapeutically useful substance. The biocompatible membrane composite is formed of a cell impermeable layer and a mitigation layer. The cell encapsulation device maintains an optimal oxygen diffusion distance through the design of the cell encapsulation device or through the use of lumen control mechanisms. Lumen control mechanisms include a reinforcing component that is also a nutrient impermeable layer, internal structural pillars, internal tensioning member(s), and/or an internal cell displacing core.
