Temporary microvascular occluder

Claim 1

A microvascular occluder comprising a base integral with a stem, said stem comprising a pair of compressible, non-inflatable, tubular arms projecting in proximate, normally-divergent relationship from said base for capturing a blood vessel immediately at said base and extending transversely between said arms, each of said arms comprising a normally-soft, tubular element, one of said arms being shorter than the other and having a free end; said arms having a rounded contour-flexibility and pliability for providing gentle contact with a blood vessel being compressed and causing minimal endothelia damage to said blood vessel when it is being compressed; and cuff means comprising a sleeve on said other arm and normally captured thereon and slidable over said free end of said one arm and over both said arms in unison for gradually and progressively compressing said arms onto the captured transverse blood vessel between said cuff means and said base for gradually and softly applying pressure to said transverse blood vessel with minimal degree of endothelial damage and occluding the passage of blood therethrough, said other arm having stop means thereon for capturing the cuff means thereon, said base comprising a flat element integral with adjacent ends of said arms and sealing them off thereat, said base extending laterally of said adjacent ends of said arms and maintaining said arms in the normal divergent relationship when said occluder is being applied on a said blood vessel and providing means for handling said occluder and providing means for supporting said occluder in an operative position.
