ABSTRACT:
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.
