A tubular support for supporting vessels made of living tissue in an anastomosis procedure is disclosed. The support is biased so as to resiliently and elastically maintain a predetermined length and diameter. The support has ends insertable into the lumens of the vessels through openings, either in the end or in an incision in the vessel sidewall. The ends are compressed radially to a smaller diameter upon insertion and expand due to the biasing force to engage each vessel and support them in proximity to one another for surgically joining, for example, by suturing. The tubular support is formed by braiding elastic filamentary members into a tubular configuration under tension to provide the biasing force or by braiding resilient filamentary members into a tubular configuration. The tubular support may be made of bio-absorbable material or it may have an elastic, fluid impermeable membrane. |
