Minimally invasive medical apparatus for dispensing a biologically active compound and an associated medical procedure for dispensing a biologically active compound

Abstract

A medical apparatus for dispensing a biologically active compound. The medical apparatus includes a sleeve, wherein ( 1 ) the sleeve has a working channel defined therein through which medical instruments may be advanced, ( 2 ) the sleeve includes a fluid delivery channel which is distinct from the working channel, ( 3 ) the fluid delivery channel has an exit, and ( 4 ) the sleeve includes a housing having an interior cavity defined therein. The medical apparatus also includes an insufflation valve in fluid communication with the working channel. The insufflation valve is positionable between an open position and a closed position such that (i) when the insufflation valve is located in the open position an insufflation gas can be advanced into the working channel and (ii) when the insufflation valve is located in the closed position the insufflation gas is prevented from being advanced into the working channel. The medical apparatus further includes a chemical container having an interior void defined therein for receiving the biologically active compound, wherein the interior void is in fluid communication with the exit through the fluid delivery channel when the chemical container is positioned within the interior cavity of the housing such that the biologically active compound may be delivered through the fluid delivery channel to an outer surface of the sleeve.

1 . A medical apparatus for dispensing a biologically active: compound while performing a minimally invasive surgical procedure in a non-vascular body cavity, comprising:
 a sleeve having an open distal end, wherein (1) said sleeve has a working channel defined therein through which medical instruments may be advanced into the non-vascular body cavity, (2) said sleeve defines a fluid delivery channel which is distinct from said working channel, and (3) said fluid delivery channel has an exit;   a housing secured to said sleeve, said housing having an interior void defined therein for receiving said biologically active compound, wherein said interior void is in fluid communication with said exit through said fluid delivery channel such that said biologically active compound may be delivered through said fluid delivery channel to an outer surface of said sleeve; and   a trocar having a closed converging distal tip positionable between a first trocar position and a second trocar position, said trocar being located within said working channel of said sleeve with said tip projecting from said open distal end of said sleeve when said trocar is positioned in said first trocar position, and said trocar is completely removed from said working channel of said sleeve when said trocar is positioned in said second trocar position.   
   
   
       2 . The medical apparatus of  claim 1 , wherein said fluid delivery channel is defined in a wall of said sleeve. 
   
   
       3 . The medical apparatus of  claim 2 , wherein said fluid delivery channel includes a groove defined in a surface of said sleeve. 
   
   
       4 . The medical apparatus of  claim 1 , wherein said sleeve further includes a number of sealing members extending therefrom. 
   
   
       5 . The medical apparatus of  claim 1 , wherein said housing is integrally formed with said sleeve. 
   
   
       6 . The medical apparatus of  claim 1 , wherein said fluid delivery channel is a void space. 
   
   
       7 . A medical apparatus for dispensing a biologically active compound while performing a minimally invasive surgical procedure in a non-vascular body cavity, comprising:
 a sleeve having an open distal end, wherein (1) said sleeve has a working channel defined therein through which medical instruments may be advanced into the non-vascular body cavity, (2) said sleeve defines a fluid delivery channel which is distinct from said working channel, and (3) said fluid delivery channel has an exit;   a housing secured to said sleeve, said housing having an interior void defined therein for receiving said biologically active compound, wherein said interior void is in fluid communication with said exit through said fluid delivery channel such that said biologically active compound may be delivered through said fluid delivery channel to an outer surface of said sleeve;   a trocar having a closed converging distal tip positionable between a first trocar position and a second trocar position, said trocar being located within said working channel of said sleeve with said tip projecting from said open distal end of said sleeve when said trocar is positioned in said first trocar position, and said trocar is completely removed from said working channel of said sleeve when said trocar is positioned in said second trocar position; and   a pressure source operatively coupled to the housing for pressurizing the biologically active compound.   
   
   
       8 . The medical apparatus of  claim 7 , wherein said fluid delivery channel is defined in a wall of said sleeve. 
   
   
       9 . The medical apparatus of  claim 7 , wherein said fluid delivery channel includes a groove defined in a surface of said sleeve. 
   
   
       10 . The medical apparatus of  claim 7 , wherein said sleeve further includes a number of sealing members extending therefrom. 
   
   
       11 . The medical apparatus of  claim 7 , wherein said housing is integrally formed with said sleeve. 
   
   
       12 . The medical apparatus of  claim 7 , wherein said fluid delivery channel is a void space.
