Abstract
Cannula assemblies and related methods are provided. In accordance with one embodiment, a cannula assembly includes a tubular structure coupled with a flange assembly. The flange assembly includes a plurality of wireform loops disposed in a circumferential, woven pattern about an end of the tubular structure. The flange assembly is configured to exhibit a first, collapsed state wherein the plurality of wireform loops extend substantially axially from the tubular structure, and a second, expanded state wherein the plurality of wireform loops extend in a direction having a substantial radial component relative to the tubular structure. In another embodiment, a cannula assembly includes a conformal flange coupled with a tubular structure, wherein the tubular structure extends both distally and proximally of the flange.
