First Claim
1. An apparatus, comprising:
- an elongate body disposable within a body lumen of a patient; and
an expandable member coupled to the elongate body, the expandable member having a collapsed configuration and an expanded configuration, the expandable member when in the expanded configuration configured to substantially prevent distal migration of biological material within the body lumen during a medical procedure being performed in the body lumen using a medical device different than the elongate body.

Abstract
An apparatus according to an embodiment of the invention includes an elongate body disposable within a body lumen of a patient. An expandable member is coupled to the elongate body. The expandable member has a collapsed configuration and an expanded configuration. The expandable member when in the expanded configuration is configured to substantially prevent distal migration of biological material within the body lumen during a medical procedure being performed in the body lumen using a medical device different than the elongate body. In another embodiment, an apparatus includes an expandable member having a collapsed configuration and an expanded configuration and a membrane is coupled to the expandable member. The membrane is configured and formulated to maintain adequate structural integrity when exposed to laser energy applied during a lithotripsy procedure performed within a body lumen when the expandable member is disposed within the body lumen.
