               1. A medical device, comprising: 
            a delivery device including a tube having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end; and 
                a member having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end, wherein the lumen is configured to apply suction through the distal end of the member, wherein at least a distal portion of the member is D-shaped with a flat side and a rounded side extending from opposing ends of the flat side; 
                wherein at least one of the tube or the member is axially movable relative to the other of the tube or the member; 
                wherein at least a portion of a circumferential exterior of the tube abuts a portion of the flat side of the member; and 
                wherein an outer portion of the tube includes a flat engaging surface that is complementary to the flat side of the distal portion of the member.

               7. A medical device, comprising: 
            a tube having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end; and 
                a member having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end, wherein the lumen is configured to apply suction through the distal end of the member, wherein at least a distal portion of the member is D-shaped with a flat side and a rounded side extending from opposing ends of the flat side, 
                wherein at least a portion of a circumferential exterior of the tube includes a flat engaging surface that is complementary to and abuts a portion of the flat side of the member, 
                wherein the tube includes a partially circular portion extended from opposite sides of the flat engaging surface, and 
                wherein at least one of the tube or the member is axially movable relative to the other of the tube or the member.

               14. A medical device, comprising: 
            a delivery device including a tube having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end; and 
                a member having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end, wherein the lumen is configured to apply suction through the distal end of the member, wherein at least a distal portion of the member is D-shaped with a flat side and a rounded side extending from opposing ends of the flat side; 
                wherein the member is axially movable relative to the tube such that the member is extendable distally of the tube, 
                wherein at least a portion of a circumferential exterior of the tube abuts a portion of the flat side of the member, 
                wherein an outer portion of the tube includes a flat engaging surface that is complementary to the flat side of the distal portion of the member, and 
                wherein another outer portion of the tube includes a rounded portion extending from opposite sides of the flat engaging surface.
