FIELD: medicine.
SUBSTANCE: invention relates to medical equipment. Curved surgical needle comprises an elongated body having a piercing point and a proximal surgical suture mounting end. Body comprises at least one lateral flat face along at least part of the body. Needle is made of a refractory metal alloy containing from about 70 wt% to less than about 95 wt% of tungsten and from more than about 5 wt% to about 30 wt% of rhenium. Alloy has a strength of about 450 ksi to about 590 ksi. T to X ratio of the lateral flat face of the body ranges from about 1.0 to about 1.2.
EFFECT: needle has higher resistance to cracking.
