System and method for minimally invasive disease therapy

Abstract

A system for treating a lesion site of a patient is disclosed. The system includes a cannula having a lumen, a conduit in communication with said lumen, an introducer stylet removably disposed within said cannula, a resecting device selectively insertable within said cannula, and an adjuvant treatment device selectively insertable within said cannula.

1 . A medical procedure, comprising the steps of:
 inserting an introducer stylet having an outer cannula disposed thereon into a patient's body creating a pathway to a lesion site;   removing the introducer stylet from the outer cannula, while leaving the outer cannula in place;   inserting an adjuvant therapy device into the outer cannula such that a portion of the adjuvant therapy device extends distally from the outer cannula;   collapsing said lesion site around the portion of the adjuvant therapy device by applying a vacuum to said outer cannula; and   treating said lesion site with said adjuvant therapy device.   
     
     
         2 . The procedure of  claim 1 , further including resecting tissue from the lesion site through the outer cannula prior to inserting the adjuvant therapy device. 
     
     
         3 . The procedure of  claim 1 , wherein said treatment is continued until a margin surrounding the lesion site has been confirmed using an imaging modality. 
     
     
         4 . The procedure of  claim 1 , further comprising:
 injecting a fluid through said outer cannula before, during, or after any step.   
     
     
         5 . The procedure of  claim 4 , wherein said fluid is at least one of an anesthesia, saline, photosensitizing agent, and a haemostatic agent. 
     
     
         6 . The procedure of  claim 1 , further comprising:
 removing a fluid through said outer cannula before, during, or after any step.   
     
     
         7 . The procedure of  claim 6 , wherein said fluid is at least one of a bodily fluid, blood, an anesthesia, saline, photosensitizing agent, and a haemostatic agent.
