Applicator for microwave radiation treatment

摘要

A device for restricting the loss of blood during a surgical procedure, comprising an applicator (3) including a source (1) of radiation in the form of a waveguide (6), the applicator including an array (15) of retractable needles arranged so as to extend from one face of the applicator (3); the waveguide (6) and the array (5) of needles when extended defining a volume whose dimensions correspond to those of the tissue volume which is to be heated; and where, in operation, the array (5) of needles serves to confine the irradiated energy field emanating from the applicator (3).
