Abstract

The invention relates to a medical retrieval device (2) with a basket (10) that has at least one leg (11a, 11b, 11c, 11d) that is frangible (i.e., easily breakable) and/or able to dissociate from at least one other leg (11a, 11b, 11c, 11d) upon the application of a predetermined force to the basket (10). The invention allows an operator to release captured material (50) (e.g., a stone) from the basket (10) when the device (2) is still inserted in the body. In an embodiment, the basket legs (11a, 11b, 11c, 11d) associate by a magnetic interaction that can be overcome by applying a predetermined force to the basket (10). In yet another embodiment, the invention provides a basket (10) with at least two legs (11a, 11b, 11c, 11d) that are joined together by a joining member by means of at least one shear pin (46) that can break upon the application of a predetermined force.
