Abstract: Apparatuses and methods for providing audio, visual and/or tactile feedback during assembly of two mating medical fluid connectors and a retention force are provided. The invention includes a first connector defining a first lumen and a second connector defining a second lumen. The first and second connectors are threaded together to enable the first lumen to initially communicate fluidly with the second lumen after the first and second connectors are engaged. The first connector defines a first engaging member and the second connector defines a second engaging member, the engaging members mating to provide (i) feedback indicating that a mating of the first and second connectors is at least substantially complete and (ii) a retention force tending to hold the first and second connectors together. An improved apparatus for releasing a sealed disinfectant is also provided.

Abstract: A catheter suitable for use in performing peritoneal dialysis. The catheter is a dual lumen catheter which allows for continuous flow peritoneal dialysis. Dialysate flows through the catheter into the patient via one lumen and simultaneously flows through the catheter out of the patient via the second lumen. The dual lumen dialysis catheter has a flexible tube which has an implantable portion extending from an external patient portion. Both of the lumens have openings in the external patient portion for connecting to a supply and drain of dialysate, respectively. The implantable portion has a preformed curved segment which has an outlet for the first lumen to flow dialysate into the patient's peritoneal cavity. The implantable portion has an opening for the second lumen at the distal end to flow dialysate out of the peritoneal cavity and removal from the patient. The catheter facilitates mixing of fresh and spent dialysate inside the peritoneal cavity by inflowin g fresh dialysate into the cavity at a location substantially separated from t he cavity outflow location, and by directing the inflow of dialysate into the cavity opposite the cavity outflow location.

The catheter facilitates mixing of fresh and spent dialysate inside the pentoneal cavity by inflowing fresh dialysate into the cavity at a location substantially separated from the cavity outflow location, and by directing the inflow of dialysate into the cavity opposite the cavity outflow location.

Abstract: Se proporcionan aparatos y metodos para proporcionar realimentacion de audio, visual y/o tactil durante el ensamble de dos conectores de fluido medico de acoplamiento y una fuerza de retencion. La invencion incluye un primer conector que define un primer lumen y un segundo conector que define un segundo lumen. El primer y segundo conectores se enroscan juntos para permitir que el primer lumen se comunique inicialmente de forma fluida con el segundo lumen despues de que el primer y segundo conectores se acoplan. El primer conector define un primer miembro de acoplamiento y el segundo conector define un segundo miembro de acoplamiento, los miembros de acoplamiento acoplandose ara proporcionar (i) realimentacion que indica que un acoplamiento de primer y segundo conectores esta al menos substancialmente completo y (ii) una fuerza de retencion que tiende a sostener el primer y segundo conectores juntos. Tambien se proporciona un aparato mejorado para la liberacion de un desinfectante sellado.

Abstract: A catheter is provided which has been optimized so as to become mistake-proof, user-friendly, and manually connectable to a transfer device by which the patient may hook up the catheter to a source of dialysis fluid. The catheter of the invention preferably has an outer segment which is softer than the harder internal segment and affords greater comfort to the patient. In addition, the catheter has an enlarged outer portion to lower interference and allow the catheter to be manually connected to a suitable connection device, and contains overmolded segments that can have different diameters and cross-sections so that the catheter may be optimized to meet differing requirements in any specific peritoneal dialysis operation while maintaining the integrity and structure of a non-segmented catheter. The catheter can also be made with at least two lumens wherein the lumens have a unique geometric shape so as to fit in lock-and-key fashion to suitable connection devices.
