Tactical detachable anatomic containment device and therapeutic treatment system

Abstract

Devices and methods for the controlled delivery of therapeutic agents into bone and soft tissue to prevent the unintentional migration of therapeutic agents from the treatment site. The containment device can be made of a fabric or membrane that is porous, semi-porous, non-porous, bio-resorbable, or non-resorbable materials. A containment device is advanced to the interior of the target structure and filled with a therapeutic agent. The containment device may be permanently or temporarily implanted. Where permanent implantation is desired, the containment device may be detached via a severable junction.

What is claimed is:  
     
         1 . A medical containment device for use in a bony body comprising: 
 a generally hollow body conformable to an interior cavity of a bony body having an opening through which a therapeutic material may be inserted, the generally hollow body providing a barrier preventing the unintentional migration of the therapeutic material from the interior of the generally hollow body; and    a delivery device to convey the generally hollow body into an interior of a bony body through an opening in the bony body, wherein the generally hollow body is attached to a distal end of the delivery device.    
     
     
         2 . The medical device of  claim 1 , wherein the generally hollow body is made from a flexible or conformable material, sufficient to achieve optimal anatomic fit and clinical function.  
     
     
         3 . The medical device of  claim 1 , wherein the generally hollow body has a pouch shape.  
     
     
         4 . The medical device of  claim 1 , wherein the generally hollow body contains a therapeutic material.  
     
     
         5 . The medical device of  claim 4 , wherein the therapeutic material is a bone cement.  
     
     
         6 . The medical device of  claim 5 , wherein the bone cement seals the containment device.  
     
     
         7 . The medical device of  claim 1 , wherein the deliver device is a catheter.  
     
     
         8 . The medical device of  claim 1 , further comprising a system to monitor healing and/or stimulate therapeutic responses.  
     
     
         9 . The medical device of  claim 1 , wherein the generally hollow body is detachable from the delivery device.  
     
     
         10 . The medical device of  claim 9 , wherein the delivery device comprises a severable junction adapted to dissolve upon exposure to an aqueous environment.  
     
     
         11 . A medical containment device for use in a vertebral body comprising: 
 a generally hollow body having an opening through which a bone cement may be inserted, the generally hollow body providing a barrier preventing the unintentional migration of the bone cement from the interior of the containment device; and    a delivery device to convey the generally hollow body into an interior of a bony body through an opening in the bony body, wherein the generally hollow body is attached to a distal end of the delivery device.    
     
     
         12 . The medical device of  claim 11 , wherein the generally hollow body contains a therapeutic material.  
     
     
         13 . The medical device of  claim 12 , wherein the therapeutic material is a bone cement.  
     
     
         14 . The medical device of  claim 11 , wherein the generally hollow body has a pouch shape.  
     
     
         15 . The medical device of  claim 11 , wherein the generally hollow body is detachable from the delivery device.
