A vascular closure device includes a delivery assembly, an anchor member carried by the delivery assembly, and a suture attached to the anchoring member. A plug member can be disposed in the delivery assembly and attached to suture such that the plug member. The plug member includes a plug body, a pair of ridges that project from the plug body, and a select location disposed between the pair of ridges. The plug member configured to, in response to a force applied to the select location, transition from an insertion configuration, whereby the plug member is elongate along an insertion direction, into a collapsed configuration, whereby the plug member is collapsed along the insertion direction.

1. A vascular closure device, comprising: a delivery assembly configured to be inserted into a puncture of a vessel;an anchor member carried by the delivery assembly;a suture attached to the anchor member and extending into the delivery assembly; anda plug member disposed in the delivery assembly, the plug member attached to the suture so that the plug member is proximal to the anchor member, the plug member including a plug body that is elongate along a central longitudinal axis of the plug member when the plug member is in an insertion configuration, anda pair of ridges that: a) project from the plug body and on either side of the longitudinal axis, andb) are elongate along the longitudinal axis when the plug member is in an insertion configuration,the plug body further including a select location comprising a plurality of proximal apertures and a plurality of distal apertures that are disposed between the pair of ridges,the plurality of proximal apertures including a first aperture disposed along the central longitudinal axis and a second aperture offset from the central longitudinal axis, the plurality of distal apertures including at least one aperture offset from the central longitudinal axis,wherein the suture is attached to the plug member through the plurality of proximal apertures and the plurality of distal apertures,wherein the plug member is configured to, in response to a force applied to the select location, transition from the insertion configuration, whereby the plug member is elongate along the insertion direction, into a collapsed configuration, whereby the plug member is collapsed along the insertion direction,wherein when the plug member is deployed against the puncture in the collapsed configuration, a portion of the plug body and a portion of the pair of ridges cover the puncture and conforms to a shape of the vessel adjacent the puncture. 2. The vascular closure device of claim 1, further comprising a lock member attached to the suture and configured to abut the plug member, wherein the lock member is configured to apply the force against the plug member, thereby causing the plug member to conform to the shape of the vessel. 3. The vascular closure device of claim 1, wherein when the plug member is in the insertion configuration, 1) the plug body is elongate along a first direction that is aligned with insertion direction, and 2) the at least one pair of ridges are spaced apart with respect to each other along second direction that is angularly offset with respect to the first direction. 4. The vascular closure device of claim 3, where each ridge of the pair of ridges project from the plug body along a third direction that is angularly offset with respect to the first and second directions. 5. The vascular closure device of claim 3, wherein the pair of ridges include a first ridge and a second ridge, and each ridge projects from the plug body in different directions. 6. The vascular closure device of claim 3, wherein the pair of ridges is a first pair of ridges, and the second direction is a transverse direction, wherein the plug member includes a second pair of ridges, and at least one of the first pair of ridges and the second pair of ridges project from the plug body in a first transverse direction aligned with the transverse direction, and the other of the at least one first and second pairs of ridges project from the body in a second transverse direction that is different than the first transverse direction. 7. The vascular closure device of claim 1, wherein the plug body defines a first edge and a second edge opposite the first edge, and each ridge is disposed along at least a portion of a respective one of the first and second edges. 8. The vascular closure device of claim 7, wherein each ridge of the pair of ridges include at least one groove. 9. The vascular closure device of claim 1, wherein the plug body defines a first thickness and the pair of ridges define a second thickness that is greater than the first thickness when the plug member is in the insertion configuration.
