Audible And Tactile Feedback

Abstract

A rotational locking mechanism for securing a catheter to a surgical implant is disclosed. The locking mechanism includes a deflectable extension extending from the surgical implant about the catheter attached to the surgical implant. The shape of the deflectable extension defines a slot therein. A connector having at least one tab extending therefrom is placed about the catheter at the point of attachment to the surgical implant. Rotation of the tubular connector brings at least one tab of the connector into contact with the slot in the deflectable extension and deflects and releases at least a portion of the slot as the connector rotates from an unlocked position to a locked position within the slot. The rotation motion secures the catheter to the surgical implant, and produces a feedback detectable by a surgeon rotating the tubular connector.

       21 . An implantable surgical injection port having an undeployed position, and a deployed position wherein it is attached to tissue, said port comprising:
 a. a housing having a closed distal end, open proximal end and a fluid reservoir therebetween;   b. a needle penetrable septum attached to said housing about said opening; and   c. at least two attachment mechanisms mounted to said housing at a pivot point along an outer periphery of said housing, said attached mechanisms comprising arcuate hooks having a length extending substantially greater than 90° about
 said pivot point said hooks having an undeployed position and a deployed position, and an actuator configured to simultaneously move said hooks from said deployed position to said undeployed position. 
   
   
   
       22 . The injection port of  claim 1  wherein said housing includes at least one recessed portion at said distal end thereof for receiving a free end of said attachment mechanism when said port is in its deployed position. 
   
   
       23 . The injection port of  claim 1  wherein each said arcuate hook has length extending at least 180°. 
   
   
       24 . The injection port of  claim 1  wherein each said attachment mechanism includes a sharp free end. 
   
   
       25 . The injection port of  claim 1  further including a catheter connection tube attached to said housing and in fluid communication with said reservoir. 
   
   
       26 . The injection port of  claim 1  wherein said housing comprises titanium. 
   
   
       27 . The injection port of  claim 1  wherein said septum self seals after being punctured by a needle and the needle is withdrawn. 
   
   
       28 . The injection port of  claim 1  wherein said septum comprises silicone. 
   
   
       29 . The injection port of  claim 1  wherein said injection port includes at least three said attachment mechanisms. 
   
   
       30 . The injection port of  claim 9  wherein said attachment mechanisms are equally spaced along said outer periphery. 
   
   
       31 . The injection port of  claim 1  wherein said outer periphery of said injection port is adjacent said distal end of said housing. 
   
   
       32 . An implantable surgical injection port having an undeployed position, and a deployed position wherein it is attached to tissue, said port comprising:
 a housing a closed distal end, a open proximal end and a fluid reservoir therebetween;   a needle penetrable septum attached to said housing about said opening; and   at least two attachment mechanisms mounted to said housing at a pivot point along an outer periphery of said housing, said attachment mechanisms comprising an arcuate hook pivotable with respect to said housing, said hook having length extending substantially at least 180° about said pivot point said hooks having an undeployed position and a deployed position, and an actuator configured to simultaneously move said hooks from said deployed position to said undeployed position; and   said housing further including at least one recessed portion at said distal end thereof for receiving said free end of said attachment mechanism when said port is in its deployed position.   
   
   
       33 . The injection port of  claim 12  wherein said free end is sharp. 
   
   
       34 . The injection port  claim 12  further including a catheter connection tube attached to said housing and in fluid communication with said reservoir. 
   
   
       35 . The injection port of  claim 12  wherein said housing comprises titanium. 
   
   
       36 . The injection port of  claim 12  wherein said septum self seals after being punctured by a needle is withdrawn. 
   
   
       37 . The injection port of  claim 12  wherein said septum comprises silicone. 
   
   
       38 . The injection port of  claim 12  wherein said injection port includes at least three said attachment mechanisms. 
   
   
       39 . The injection port of  claim 12  wherein said attachment mechanisms are equally spaced along said outer periphery. 
   
   
       40 . The injection port of  claim 12  wherein said outer periphery of said injection port is adjacent said distal end of said housing.
