First Claim
Patent Images
1. A gastrointestinal aspirating device comprising:
- an elongated tube including an aspirating lumen defined by a wall, said wall having a plurality of aspirating orifices located therethrough; and
a selectively removable elastic sleeve, located about a portion of the elongated tube and covering some of said plurality of aspirating orifices, for enabling an operator to remove a section of the selectively removable elastic sleeve from the tube to expose at least one of the aspirating orifices,wherein said elongated tube further includes a feeding lumen, said feeding lumen having an external end portion adapted to be positioned outside a patient'"'"'s body for receiving a supply of food, said feeding lumen further having an internal end portion adapted to be positioned in a gastrointestinal section of said patient'"'"'s body, said internal end portion having a feeding orifice for discharging said food,and wherein said elongated tube includes first and second distinct groups of aspirating orifices, said second group of aspirating orifices disposed closest to the feeding orifice, and wherein said selectively removable elastic sleeve covers the aspirating orifices in said second group.

2. A gastrointestinal aspirating device comprising:
-
an elongated tube including an aspirating lumen defined by a wall, said wall having a plurality of aspirating orifices located therethrough; and a cuttable elastic sleeve, located about a circumference of the elongated tube, for achieving both a first position that covers some of said plurality of aspirating orifices, and a second position achieved by removing a section of the sleeve from the elongated tube so that at least one of the covered aspirating orifices is exposed, wherein the elongated tub has an outside, and wherein said sleeve has an inside diameter diameter that is smaller than the outside diameter of the elongated tube, the inside diameter is sufficient to substantially inhibit relative movement between the sleeve and the elongated tube, and wherein said elongated tube further defines a feeding lumen located within a length of the wall of the elongated tube and being parallel to the aspirating lumen, said feeding lumen having an external end portion adapted to be positioned outside a patient'"'"'s body for receiving a supply of food, said feeding lumen further having an internal end portion adapted to be positioned in a gastrointestinal section of said patient'"'"'s body, said internal end portion having a feeding orifice for discharging said food. - View Dependent Claims (3)

4. A gastrointestinal aspirating device comprising:
-
a) an elongated tube including an aspirating lumen defined by a wall, said wall having a plurality of aspirating orifices located therethrough; b) a selectively removable elastic sleeve, located about a portion of the elongated tube and covering some of said plurality of aspirating orifices, for enabling an operator to remove a section of the selectively removeable elastic sleeve from the tube to expose at least one of the aspirating orifices; c) the elongated tube further comprises a feeding lumen located within the wall of the elongated tube and being parallel to the aspirating lumen, said feeding lumen having an external end portion adapted to be positioned outside a patient'"'"'s body for receiving a supply of food, said feeding lumen further having an internal end portion adapted to be positioned in a gastrointestinal section of said patient'"'"'s body, said internal end portion having a feeding orifice for discharging said food; and d) said elongated tube includes first and second distinct groups of aspirating orifices, said second group of aspirating orifices disposed closest to the feeding orifice, and wherein said selectively removable elastic sleeve covers the aspirating orifices in said second group.
