Abstract
A body cavity access assembly includes a conduit having an exterior surface, a dispensing mechanism, and a reservoir for receiving a biologically active compound. The exterior surface of the conduit has first exit port and a second exit port defined therein which are in fluid communication with the reservoir. The first exit port and the second exit port are selectively positionable between an open mode of operation and a closed mode of operation with the dispensing mechanism. An associated medical procedure for dispensing a biologically active compound is also disclosed.
Claims17
A body cavity access assembly, comprising:
- a conduit having a lumen through which a medical instrument may be advanced, an exterior surface, a liquid input adapted to be coupled to a source of liquid, said liquid input communicating with a plurality of exit ports defined along a portion of said exterior surface, and
- a dispensing mechanism operatively coupled to said conduit, said dispensing mechanism being adjustable to selectively open said exit ports thereby allowing the liquid to flow therefrom and to selectively close at least one of said exit ports to prevent the liquid from flowing therefrom.
A body cavity access assembly, comprising:
- a conduit having (i) a lumen through which a medical instrument may be advanced, (ii) an exterior surface, (iii) a first exit port defined in said exterior surface, said first exit port being (A) operable between an open mode of operation and a closed mode of operation and (B) adapted to be in fluid communication with an interior void of a reservoir containing a liquid and (iv) a second exit port defined in said exterior surface, said second exit port being (A) operable between an open mode of operation and a closed mode of operation and (B) adapted to be in fluid communication with said interior void of said reservoir;
- and
- a dispensing mechanism operatively coupled to said first exit port and said second exit port, such that (i) said dispensing mechanism can selectively place said first exit port in (A) said open mode of operation so that said liquid may be advanced through said first exit port or (B) said closed mode of operation so that said liquid is prevented from being advanced through said first exit port and (ii) said dispensing mechanism can selectively place said second exit port in (A) said open mode of operation so that said liquid may be advanced through said second exit port or (B) said closed mode of operation so that said liquid is prevented from being advanced through said first second exit port.
A method for dispensing a liquid during a surgical procedure, comprising:
- creating an opening in a wall of a body cavity,
- advancing a conduit through the opening, said conduit having a lumen through which a medical instrument may be advanced, and an exterior surface having a variable size dispensing zone extending along a length thereof,
- discharging the liquid from the dispensing zone,
- changing the size of the dispensing zone, and
- discharging the liquid from the dispensing zone of changed size.
