Abstract: In one example, a retrieval device may include a flexible loop; a mesh coupled to the loop, the mesh having an opening at least partially circumscribed by the loop; a sheath extending from a proximal end to a distal end; a cord extending through and/or around the mesh; and a connector assembly movable from a first configuration to a second configuration. In the first configuration, the flexible loop, the mesh, and the cord may be coupled to the sheath, and in the second configuration, the flexible loop, the mesh, and the cord may be detached from the sheath.

Abstract: A medical device may comprise a distal tip having a viewing element, a lighting element, and at least one feature configured to removably couple the distal tip to a shaft. The medical device may also comprise a working channel coupled to the distal tip and defining a central lumen configured to receive a tool. A wall of the working channel may define at least one additional lumen. The working channel may be configured to be removably inserted into the shaft. The medical device may also comprise at least one of a wire, a cable, or a conduit passing through the at least one additional lumen.

Abstract: A method for removing one or more objects or materials from a body lumen includes delivering a tube and an expandable device to the body lumen to a position proximal to the one or more objects or materials. The expandable device is positioned with a lumen of the tube, and the expandable device includes a lumen extending from a distal portion to a proximal portion. The method further includes proximally retracting the tube such that the expandable device remains in the position proximal to the one or more objects or materials, distally advancing the expandable device such that the distal portion of the expandable device at least partially surrounds the one or more objects or materials, at least partially closing a distal end of the expandable device, and moving the expandable device proximally to remove the expandable device and the one or more objects or materials from the lumen.

Abstract: A medical device that includes an outer shaft, an inner shaft disposed within the outer shaft, and a tube disposed within the inner shaft and the outer shaft. The medical device includes a first expandable member having a proximal end secured to the outer shaft and a distal end secured to the inner shaft. The inner shaft and the tube are received through the first expandable member. The first expandable member is configured such that the proximal end is movable relative to the distal end when the outer shaft moves relative to the inner shaft. The first expandable member is configured to radially expand when the proximal end moves toward the distal end and radially compress when the proximal end moves away from the distal end.

Abstract: A medical instrument may include a tube, a sheath provided around and coaxial with the tube, and an inflatable balloon at a distal end of the sheath. The balloon may receive a fluid from a lumen of the sheath, and may have a central opening along a longitudinal axis thereof, and into which the tube extends, a proximal portion, a middle portion adjacent to and distal of the proximal portion, and a distal portion adjacent to and proximal of the middle portion. When the balloon is inflated with the fluid, a maximum diameter of the middle portion may be less than a maximum diameter of the proximal portion, and less than a maximum diameter of the distal portion. The medical instrument may also include an extraction member provided at a distal end of the tube, distal to the balloon, and movable axially relative to the balloon.

Abstract: A medical device includes a handle including a stationary body, a first movable body, and a second movable body; a control member coupled to the second movable body; an intermediate sheath coupled to the first movable body; an external sheath coupled to the stationary body; and an end effector. The end effector includes a first loop and a second loop. The first loop includes a first arm and a second arm, and the first arm is coupled to the intermediate sheath. The second arm is coupled to the control member, and the second arm includes a first plurality of teeth. The second loop includes a third arm and a fourth arm. The third arm is coupled to the intermediate sheath, and the fourth arm is coupled to the control member. The fourth arm includes a second plurality of teeth.
