  • Colon motility is characterized by stronger pressure waves (50-100 mmHg) which are short (several seconds) in the proximal colon but much longer (up to almost static) in the distal colon.
  • the poroelastic structure should be elastic enough (not brittle) to withstand at least one cycle of compressing to its compressed packed state and decompressing to its expanded state in the gastro-intestinal tract.
  • the poroelastic structure can be dismantled within the colon (e.g. through degradation by bacteria fermentation), and/or compressed by the pressures in the colon to release most of the trapped fluids and particles, since there is no significant nutrients absorption at this stage.
  • poroelastic structure It is preferred that all the materials of which the poroelastic structure are built from should be generally recognized as safe and permitted to be used as food, food supplements or dietary supplements, no new dietary ingredients (e.g. regenerated cellulose).
  • Different swellable items can be used for different populations (e.g. adults vs. children), for example: different delivering options (multiparticulates Vs. capsules), different poroelastic structure dimensions (e.g. 1mm Vs. 3 mm diameter in expanded state) etc.
  • Expanding in the small intestine has several advantages: (i) gastric fluids low acidity (after neutralizing in the duodenum), so release of some of the fluids further in the small intestine or the colon due to external pressure will not cause any acid bums, (ii) not accumulating in the stomach, which could have negative impacts such as stomach pain, nausea and vomiting, and (iii) lower viscosity fluids (easier absorption in the poroelastic structure).
  • expanding within the stomach can also improve the satiety, especially if the expanded poroelastic structures are too big to exit the pyloric sphincter during standard digestion so it accumulates and released to the small intestine mostly during the interdigestive migrating motor complex, which means that the mass of expanded poroelastic structures remains in the stomach for a longer period of time.
  • the dimension requirements can be on the swellable items (before surrounding dissolving and poroelastic structures expanding) as well as on the expanded poroelastic structures.
  • the requirements are for the following: (i) delivering (swallowing), (ii) Passing from the stomach to the small intestine (through the pyloric sphincter), and (iii) Passing along the small intestine and through the ileocecal valve to the colon.
  • Pills capsules
  • the diameter of each ingested capsule should be ⁇ 8mm, and the length ⁇ 20mm, the volume is in the range of 0.5-1 CC.
  • the main drawback is the large number of such capsules required to deliver large volumes and the fact that many people (especially young) cannot or dislike swallowing large pills,
  • Multiparticulates A large number of small particles, having dimensions in the 100's of microns range (e.g. 200- 500pm), delivered as a "powder” and drunk mixed with water. This delivery option is much easier for large volumes (e.g. 10's of CC), replacing 10's of capsules.
  • the main drawback is the grittiness "sandy" feeling.
  • particles In order to pass from the stomach through the pyloric sphincter to the small intestine in parallel to the chyme during the postprandial period, particles should be up to 2mm in diameter and 5-10 mm length (depending on its stiffness, elastic structures can be somewhat larger).
  • Poroelastic structure that should expand in the stomach can be up to 2-3 mm diameter in expanded state, in which case it would transfer to the small intestine during the postprandial period, or larger than this and accumulate in the stomach until the mmc cycle, causing longer satiety period but with the risk of over accumulation in the stomach.
  • Poroelastic structure that should expand in the small intestine should be up to 2-3mm diameter in compressed state, in order to pass to the small intestine during the postprandial period and capture nutrients dissolved in the gastric fluids.
  • each particle will easily pass through the pyloric sphincter during digestive period in compressed (and probably also expanded) state.
  • the manufacturing process for these "sponge like" open cell porous structure can be based on a wide variety of known methods, either for textile fibers and non-woven fabrics manufacturing (e.g. cellulose regeneration for fibers such as rayon fibers), filtration polymer membrane manufacturing (e.g. casting plus particulate leaching), tissue engineering / polymer scaffold manufacturing (e.g. extrusion foaming followed by porogen leaching) or even aerogel manufacturing (e.g. polymer dissolving, solvent exchange and freeze drying).

  • filtration polymer membrane manufacturing e.g. casting plus particulate leaching
  • tissue engineering / polymer scaffold manufacturing e.g. extrusion foaming followed by porogen leaching
  • aerogel manufacturing e.g. polymer dissolving, solvent exchange and freeze drying.
  • the manufacturing process can start with a solution (polymer dissolved in a solvent), a molten or softened thermoplastic polymer or a liquid containing monomers or non crosslinked polymer that will later on precipitate or coagulate into a polymeric structure.
  • a solution polymer dissolved in a solvent
  • a molten or softened thermoplastic polymer or a liquid containing monomers or non crosslinked polymer that will later on precipitate or coagulate into a polymeric structure.
  • These methods include for example: (i) thermoplastic foaming (either extrusion or injection molding), creating mostly closed cell foam, followed by opening holes in the closed cells to make an open cell foam structure, e.g.
  • phase separation e.g. mixing a polymer-solvent solution with nonsolvent.
  • Emulsion templating e.g. PolyHIPE.
  • Porogen/particulate leaching e.g. table salt or calcium carbonate
  • Polymer leaching e.g. water soluble polymer such as PEO.
  • Freeze drying e.g.
  • a manufacturing process produces an "endless”, “sponge” like, poroelastic thick yarn (few millimeters diameter in non-compressed state) which has all the required mechanical and physical properties. This yam is then twisted (spinned) in order to be compressed, coated in order to hold it in compressed state and to withstand gastro-intestinal conditions until required expansion and cut to appropriate length.
  • the "endless" yarns can be drawn through all production stages (from fiber creation until cutting), it could be beneficial to roll "endless” filament fibers after process steps and un-roll in proceeding process stages.
  • One benefit can be load balancing of manufacturing processes, using several such fibers in parallel for slow processes (e.g. saponification).
  • Another benefit could be performing different manufacturing stages at different locations (e.g. by sub-contractors).
  • the manufacturing process starts with extrusion foaming of a cellulose thermoplastic derivative (e.g. ester derivative such as cellulose acetate or cellulose acetate butyrate, viscose: cellulose xanthate, cellulose propionate, ether derivative such as ethylcellulose, cellulose nitrite etc.).
  • a cellulose thermoplastic derivative e.g. ester derivative such as cellulose acetate or cellulose acetate butyrate, viscose: cellulose xanthate, cellulose propionate, ether derivative such as ethylcellulose, cellulose nitrite etc.
  • the extrusion is from a 200-300pm diameter die into an "endless" closed cell porous single filament fiber yarn with a diameter of 2-3mm.
  • the foaming can be done with the help of chemical or physical blowing agents, e.g. water, SC-CO2, N2, isobutene etc. Better volume expansion ratio is achieved with larger blowing agent molecules (lower diffusion) and lower process temperatures
  • nucleating agents can be added to improve the foaming uniformity, pores size and the volume expansion ratio.
  • a plasticizer e.g. glycerol, glycerol tri-acetate etc.
  • the yarns will be drawn and dipped in baths for further reticulation and/or leaching (opening the pores into "open cell” form and enlarging the porosity).
  • the cellulose can be regenerated (e.g. by saponification of ester derivatives such as cellulose acetate, for example by dipping in a solution of NaOH/H2O, NaOH/Ethanol or NaOMe/MeOH, similar to saponification of acetate rayon fibers to rayon as done in the case of Fortisan fibers, described in US patent 2,053,766).
  • ester derivatives such as cellulose acetate
  • Cellulose regeneration e.g. deacetylation of cellulose acetate
  • the compressed yarn goes through a bath (or air spray coating) in order to be coated with a coating that will hold the yam compressed until dissolving.
  • Such hard crystalline coating that can hold the twisted fibers is similar to hard panning of sugar, polyol (e.g. sugar alcohols), sucrose esters etc., performed by coating with multi thin layers of a syrup which crystallizes.
  • Another option is similar to soft panning, a syrup that would not crystallize but be utilized as an adhesive to a powder (e.g. confectionary sugar, sugar mixed with starch etc.) "dusted" afterwards.
  • Another coating can be applied for delayed expansion, either in acidic environment (stomach) or neutral environment (small intestine).
  • An example for such coating that can be used as enteric (dissolving only in the neutral acidity small intestine) is stearic or palmitic fatty acid (also generally recognized as safe food).
  • the coatings for mechanically holding the compressed poroelastic structure and delayed expansion can be one or two different coatings.
  • the second coating can also be provided after cutting the yam, since coating before cutting the fibers means that the fibers are not coated at the cut sides, but only around the cylindrical surface.
  • the last stage is cut the coated, compressed twisted yam to required length (in the case of multiparticulates: 200-500pm).
  • the manufacturing process starts with extrusion (without foaming) of an endless solid (non-porous) thick (2-3mm) yarn comprised of cellulose thermoplastic derivative combined with large amount of soluble particles.
  • the materials can be the same as in embodiment one, the main difference from embodiment one is that the extrusion is of a solid polymer thick fiber (through a 2-3 mm diameter die) and not a foamed thick fiber (that expands after extrusion through 200-300pm diameter die).
  • the open cell porous structure is formed by porogen/particulate leaching within a bath filled with an appropriate solvent (e.g. water for water soluble particles).
  • an appropriate solvent e.g. water for water soluble particles.
  • the manufacturing process starts with filament fibers spinning (e.g. solution blow spinning through spinnerets) of "endless" thin non-porous filament fibers which build a non-woven, tangled, "thick yarn like” poroelastic fabric.
  • filament fibers spinning e.g. solution blow spinning through spinnerets
  • An example for such a fabric creation is by spinning helical shapes downwards while the fabric is drawn to the side.
  • the spinning can be using single or multiple nozzles.
  • the helices are built in several layers and the outcome is an "endless" few hundred microns to few millimeters wide (about the helix diameter in one axis and the number of layers multiplied by the fiber diameter on the other axis, both perpendicular to the "endless” drawing axis).
  • the spinning can be of molten thermoplastic cellulose derivative, as well as dissolved cellulose derivative (e.g. viscose: cellulose xantate or dissolved cellulose diacetate in acetone) or dissolved pure cellulose (e.g. lyocell process).
  • dissolved cellulose derivative e.g. viscose: cellulose xantate or dissolved cellulose diacetate in acetone
  • pure cellulose e.g. lyocell process
  • Each fiber can be l-100pm diameter; the fabric should be 2-3 mm diameter (can also be of rectangular shape, compressed to 200-300pm diameter after twisting).
  • the materials can be the same as in embodiment one, the main difference from embodiment one is that the extrusion is of solid polymer thin fibers and not a foamed thick fiber.
