Systems and methods for trans-orifice and transperineal intervention

Abstract

An intervention apparatus is described having a probe with an orifice insertion portion, the insertion portion being configured for insertion into an orifice of a patient. The apparatus also having an intervention tool securement and adjustment mechanism removably attached to the probe. The probe providing support to hold the mechanism in a position relative to the patient, and the adjustment mechanism providing adjustment of an entry point and an angle of entry for an intervention tool to the patient. In embodiments, magnetic resonance imaging, trans-orifice intervention and transperineal intervention are described. Methods for imaging and/or intervention are also described.

1 . A method for imaging and performing intervention on a tissue of interest in a patient, comprising:
 inserting a magnetic resonance imaging (MRI) coil housed within a probe through the anus of the patient;   obtaining MRI information associated with the tissue of interest through the MRI coil; and   using the MRI information, guiding an intervention tool to the tissue of interest through an intervention tool securement and adjustment mechanism removably attached to the probe.   
     
     
         2 . The method of  claim 1 , wherein the intervention tool passes through the portion of the probe inserted through the anus into the patient's rectum, whereby the intervention tool passes through the rectal wall towards the tissue of interest. 
     
     
         3 . The method of  claim 1 , wherein the intervention tool passes transperineally into the patient towards the tissue of interest. 
     
     
         4 . The method of  claim 3 , wherein the intervention tool securement and adjustment mechanism further comprises a second MRI coil to obtain additional information associated with the tissue of interest, for use in guiding the intervention tool to the tissue of interest.
