A medical device configured to be inserted into a patient's body to retrieve material from the patient's body includes a basket assembly. The basket assembly is configured to transition between various states including an expanded state and a collapsed state. The basket assembly may be substantially covered in a flexible sheet except for a side-facing opening when the basket assembly is in the expanded state. When the basket assembly is in the collapsed state, the side-facing opening may be substantially closed. The device may be inserted into the patient's body while the basket assembly is in the collapsed state. While in the patient's body, the basket assembly may be transitioned to the expanded state. Then, a physician may maneuver material to be removed from the patient's body into the basket assembly via the side- facing opening. Next, the basket assembly may be transitioned into the collapsed state or a partially collapsed state so that the basket assembly can be removed from the patient's body.

L'invention concerne un dispositif médical configuré pour s~introduire dans le corps d'un patient afin de récupérer des matières depuis le corps du patient et comprenant un ensemble panier. L~ensemble panier est configuré pour assurer la transition entre divers états englobant un état déployé et un état replié. L~ensemble panier peut être sensiblement recouvert d~une feuille flexible à l~exception d~une ouverture dirigée latéralement lorsque l~ensemble panier est déployé. Lorsque l~ensemble panier est replié, l~ouverture dirigée latéralement peut être sensiblement fermée. Le dispositif peut s~introduire dans le corps du patient lorsque l~ensemble panier est replié. Dans le corps du patient, l~ensemble panier peut passer à l~état déployé. Alors, le praticien peut manAEuvrer les matières à enlever du corps du patient dans l~ensemble panier par le biais de l~ouverture dirigée latéralement. Ensuite, l~ensemble panier peut passer à l~état replié ou un état partiellement replié de sorte que l~ensemble panier puisse être retiré du corps du patient.
