A new self-retaining vascular indwelling catheter.
Specifications are presented for design and construction of a chronically indwelling vascular catheter. Implantation and use in fetal, neonatal, and adult sheep are described. A special feature of the catheter was the tissue-retaining lugs that ensured a high degree of stability in situ. The system was exceedingly reliable in limiting infection and thrombus formation.
