A braided surgical suture is provided which in a first embodiment is woven in a spiral braid. The suture is braided by moving thread carriers from position to position around a circular path. As each carrier moves it moves from its present position to a succeeding position which is at least two positions removed from its present position. Such spiral braided sutures are advantageously produced without core filaments, providing benefits in strength, smoothness, pliability and cylindrical uniformity without the discontinuity of properties characteristic of conventionally braided cored sutures. In a second embodiment the suture is woven in a lattice braid, providing a plurality of distributed core passageways for individual core fibers.

Surgical filaments such as sutures and ligatures are produced from block copolyetheramides. The filaments combine high strength with high compliance.

A rudder blade means of the type designed to reduce the drag produced by rudder blades of conventional design. The novel design, having utility in any vessel that travels through a fluid medium and incorporates a substantially vertically aligned chamber formed internally of the rudder body. The chamber has a narrow, slot-like portion that is in open communication with the trailing edge of the rudder body, and an enlarged, bore-like portion remote from said trailing edge but in open communication with the innermost portion of said slot-like portion. In applications where the rudder body is mounted to a sea-going vessel, and wherein such rudder body has a submerged portion and an un-submerged portion, water enters the chamber, in a counterswirling pattern, through the slot-like portion, and is driven upwardly, by water pressure, through the bore-like portion and is expelled above the water line through the uppermost region of said slot-like portion of such chamber.
