1. A composite plug for arteriotomy closure comprising: an elongate core member having a distal end, a proximal end, and a lumen connecting the distal end and the proximal end, said lumen sized to receive a suture;one or more layers disposed at least in part about the core member; andan outer member
1. A composite plug for arteriotomy closure comprising: an elongate core member having a distal end, a proximal end, and a lumen connecting the distal end and the proximal end, said lumen sized to receive a suture;one or more layers disposed at least in part about the core member; andan outer member at least partially surrounding the core member, said outer member having a distal end and a proximal end;wherein the core member comprises a gelatin foam and the one or more layers comprise a material selected from the group consisting of a hydrogel, a hemostatic material, and combinations thereof;wherein a portion of the core member extends distally with respect to the outer member;wherein distal of the one or more layers, a lateral cross-section of the composite plug includes only the elongate core member; andwherein proximal of the one or more layers, a lateral cross-section of the composite plug includes only the outer member. 2. The composite plug of claim 1, further comprising one or more regions in which a portion of the plug has been removed. 3. The composite plug of claim 2, wherein the one or more regions in which a portion of the plug has been removed is in the form of a notch. 4. The composite plug of claim 2, wherein the one or more regions in which a portion of the plug has been removed is in the form of a groove. 5. The composite plug of claim 1, wherein the core member has been modified by the inclusion of one or more slits. 6. The composite plug of claim 1, wherein the one or more layers are continuous. 7. The composite plug of claim 1, wherein the one or more layers are discontinuous. 8. The composite plug of claim 1, wherein the outer member comprises gelatin foam. 9. The composite plug of claim 1, wherein the outer member includes a lumen sized to receive a suture. 10. The composite plug of claim 9, wherein the lumen of the outer member is axially aligned with the lumen of the core member. 11. The composite plug of claim 1, wherein the outer member extends proximally with respect to the core member. 12. The composite plug of claim 1, wherein the distal end of the outer member and the portion of the core member which extends distally with respect to the outer member have substantially the same cross-section. 13. The composite plug of claim 1, wherein the one or more layers disposed about the core member are disposed at least in part between the core member and the outer member. 14. The composite plug of claim 13, wherein at least a portion of the one or more layers disposed about the core member are not covered by the outer member. 15. The composite plug of claim 1, wherein the outer member further comprises one or more layers comprising a material selected from the group consisting of a hydrogel, a hemostatic material, and combinations thereof. 16. The composite plug of claim 15, wherein the one or more layers of the outer member are continuous. 17. The composite plug of claim 15, wherein the one or more layers of the outer member are discontinuous. 18. The composite plug of claim 1, wherein the outer member further comprises a material selected from the group consisting of a hydrogel, a hemostatic material, and combinations thereof. 19. The composite plug of claim 1, wherein the outer member has been modified by the inclusion of one or more slits. 20. The composite plug of claim 1, wherein the core member further comprises a material selected from the group consisting of a hydrogel, a hemostatic material, and combinations thereof.
