A retrieval device is provided for capturing and retrieving stones, calculi, and other objects from a body. The retrieval device includes an irrigation orifice to irrigate a passageway. Irrigating the passageway helps to keep the viewing area free from debris and particulate matter.
Claims20
A retrieval device comprising:
- a retrieval tube having a proximal portion, a distal portion, and a lumen defined therethrough, wherein the retrieval tube is adapted for fitting through a passageway, wherein the distal portion of the retrieval device is biased to be disposed in a first configuration with a plurality of coils disposed in series and capable of being elastically deformed into a second relatively straight configuration;
- and
- a plurality of irrigation orifices disposed upon the distal portion of retrieval tube wherein the plurality of irrigation orifices are disposed upon the plurality of coils to urge fluid flowing through the plurality of irrigation orifices toward the proximal portion of the retrieval tube.
