Abstract: A food product containing high affinity phosphate binders (calcium and magnesium) for the purpose of chelating phosphate forms ingested foods and preventing its absorption. The chelation of phosphate in the intestine is an important part of the management of patients with moderate to severe renal failure including those in the predialysis and the dialysis dependent stages. The medicinal food product is a palatable source of calcium and magnesium which if taken without meals can be used as means to supplement those ions/salts. This concept of “food as medicine” represents a major reinforcement in the prevention and management of the derangements of divalent ion metabolism present at all levels of renal insufficiency. Limiting the gastrointestinal absorption of phosphate and consequently preventing the elevation of plasma phosphate, retards the onset of renal osteodystrophy (a Metabolic Bone Disease) and soft tissue calcification.

Abstract: A method of dialyzing renal failure patients via the peritoneum (P.O.) using a series of innovations in the dialysate composition aiming at preventing the intra vascular or intra peritoneal formation and deposition of calcium/phosphate compounds which having no excretory pathway are deposited in soft tissue and are the cause of cardiovascular related morbidity and mortality. Additionally this method allows for the use of the physiologic buffer (bicarbonate) which will improve the acid base balance and prolong the functional life of the peritoneum as the dialysis membrane.

Abstract: A refined catheter for percutaneous access to the peritoneal cavity for the deliver/removal of fluid in medical procedure such as peritoneal dialysis including a flexible tubular member having a distal portion that features either a coiled segment with multiple secondary ports and/or a bolus tip with a large scalloped orifice on the side, and a proximal segment that can be oriented cephalad or caudally by means of a 90° angle and a connecting portion with a luer fitting and an inner diameter of at least 0.375 cm is maintained (3.75 mm) through the entire length of the catheter to optimize its flow rate capabilities.

Abstract: A fixable port for use in dialysis treatment, the port having a base including a first end and a second end, each of the first and second ends having an opening and communicating through a chamber, the base having a ridge to extend into the chamber, the ridge positioned adjacent the base first end; a plunger configured to slidably fit within the base, the plunger having a first end and a second end, the plunger having a first opening and a second opening communicating through a passage, the plunger having a side wall and is configured in cylindrical shape, the plunger wall having the plunger first opening, wherein the plunger first end and the base ridge are shape to cooperate when positioned to abut blocking flow through the base; the plunger having a cowl extending from the plunger second end over the base.

Abstract: A multiple-lumen catheter is disclosed that includes a catheter tube having a generally elongate cylindrical body having an axial passageway extending the length thereof. A septum extends across the interior of the body and along the length thereof in order to divide the body into first and second lumens. A bolus extends from a distal end of the body. The bolus has a passage section including an axial passage portion and a radial passage portion. The axial passage portion is in fluid communication with the first and second lumens. The radial passage portion includes a single port through the side of the bolus whereby the first and second lumens are in fluid communication with the port. According to another form of the invention, the radial passage includes a first port and a second port therein.

Abstract: A unique catheter for percutaneous access of the peritoneal cavity, such as in peritoneal dialysis, comprising a flexible tubular member having a distal portion being caudally disposed with the periotoneal cavity and a proximal portion passing through subcutaneous and cutaneous tissues and extending externally downward along the abdominal wall. Distal and proximal portions are each angularly joined to a linear connecting portion which is substantially disposed only through the rectus muscle. The connecting portion having a length generally co-extensive with the thickness of the rectus muscle. Porous cuff means for tissue ingrowth being carried on at least the connecting portion and preferably extending the length of the connecting portion. The distal and proximal portions of the catheter being non-planar with each other.
