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 (14) which is softer than the harder internal segment (12) 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.

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 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 translation: 适合用于进行腹膜透析的导管。 导管是双腔导管，允许腹膜透析连续流动。 透析液通过一个管腔穿过导管流入患者体内，并同时经由第二管腔从患者体内流出。 双腔透析导管具有柔性管，其具有从外部患者部分延伸的可植入部分。 两个管腔在外部患者部分都具有开口，用于分别连接到透析液的供应和排出。 可植入部分具有预成型的弯曲部分，其具有用于第一内腔的透出液将透析液流入患者腹膜腔的出口。 可植入部分具有用于在远端处的第二腔的开口，以将透析液从腹膜腔中流出并从患者身上移除。 通过在与空腔流出位置基本上分离的位置处将新鲜透析液流入空腔中，并且通过将透析液的流入引导到与空腔流出位置相对的空腔中，导管便于在腹膜腔内混合新鲜和用过的透析液。

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.
