Bioswellable sutures are provided in the form of absorbable, compliant monofilaments of an amphiphilic copolyester, an absorbable multifilament braid, a non-absorbable monofilament with swellable outer layer, a non-absorbable multifilament braid with an absorbable monofilament core of an amphiphilic copolymer, and a non-absorbable, multifilament braid molecularly integrated with an outer sheath that is highly hydrophilic. |

1. A bioswellable braided coatable suture comprising multifilaments, the uncoated multifilaments comprising an absorbable polyether-ester, the polyether-ester comprising a polyether glycol end-grafted with at least one cyclic monomer selected from the group consisting of 1-lactide, glycolide, p-dioxanone, trimethylene carbonate, ε-caprolactone, 1,5-dioxepan-2-one, and a morpholinedione, the individual filaments exhibiting at least 5% increase in cross-sectional area when placed in a biological environment. |
