Patent

CA 2657222

The disclosure describes devices and methods for asymmetrical irradiation at a body cavity or site, such as after removal of tissue, e.g. biopsy or cancer. One device includes a lumen which is off-set or off-settable from a longitudinal axis to increase the intensity of radiation received from a radiation source by a first tissue portion surrounding the body cavity and to reduce or minimize radiation received by a second tissue portion (e.g. healthy tissue) surrounding the body cavity.

L'invention concerne des dispositifs et des procédés pour une irradiation asymétrique au niveau d'une cavité corporelle ou d'un site corporel, comme après le retrait d'un tissu, par exemple une biopsie ou un cancer. Un dispositif comprend une lumière qui est décalée ou décalable à partir d'un axe longitudinal pour augmenter l'intensité de rayonnement reçue à partir d'une source de rayonnement par une première partie de tissu entourant la cavité corporelle et pour réduire ou minimiser le rayonnement reçu par une seconde partie de tissu (par exemple, du tissu sain) entourant la cavité corporelle.
