1. A medical retrieval device, comprising:
- a member extending longitudinally between a proximal end and a distal end, the member including at least one lumen configured to be fluidly coupled to a vacuum source and to receive a medical tool therethrough;
wherein the member is configured to transition between a compressed configuration and an expanded configuration, wherein in the expanded configuration, the distal end has a larger cross-sectional area than the proximal end, wherein the member is trumpet shaped.

Abstract
A medical retrieval device may include a member extending longitudinally between a proximal end and a distal end. The member may include at least one lumen configured to be fluidly coupled to a vacuum source and to receive a medical tool therethrough. The member may be configured to transition between a compressed configuration and an expanded configuration, wherein in the expanded configuration, the distal end may have a larger cross-sectional area than the proximal end.

10. A medical retrieval device, comprising:
-
an elongate member extending longitudinally between a proximal end and a distal end, wherein the member includes a plurality of longitudinally-extending lumens and is configured to transition between a compressed configuration and an expanded configuration, wherein in the expanded configuration, the distal end has a larger cross-sectional area than the proximal end; and a mesh extending along at least a distal portion of the member; wherein at least one lumen of the plurality of lumens is configured to be in fluid communication with a vacuum source. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method, comprising:
-
delivering a member to an area of interest within a patient, the member extending longitudinally between a proximal end and a distal end and including a first lumen and at least one second lumen; transitioning the member from a compressed configuration to an expanded configuration, wherein in the expanded configuration, the distal end has a larger cross-sectional area than the proximal end; applying vacuum pressure through the first lumen to suction an object at least partially into the distal end; and deploying a medical tool through the at least one second lumen. - View Dependent Claims (17, 18, 19, 20)
