Abstract

A body passage foreign body extracting device includes an elongated flexible tubular rod having a compressible bulb attached to its proximal end. The bulb is in fluid communication with the rod in order to pump air through the rod. In addition, an inflatable balloon is attached to a distal end of the tubular rod and is in fluid communication with the rod. The balloon is positioned and connected with the rod so as to receive the air from the bulb and, as a result, become inflated. The extractor also includes a hand grip which is used for holding the extractor, compressing the bulb and maintaining compression with one hand.

Claims

1. A device for extracting an object from a body passage comprising:

an elongated tubular rod;

a compressible bulb means attached to a proximal end of said tubular rod and in fluid communication with said rod for pumping air through said tubular rod;

an inflatable balloon means having flexible walls configured to remove an object from the body passage attached to a distal end of said tubular rod and in fluid communication with said tubular rod for receiving said air and thereby inflating;

said balloon means adapted to be placed into the body passage and moved past said object within said body passage while in a deflated state and adapted to be inflated by said compressible bulb means when positioned behind said object so as to conform to surfaces of said body passage, engage said object and remove said object while in an inflated state upon removal from the body passage;

hand grip means positioned adjacent to and in contact with said bulb means for gripping said device and for compressing said bulb means;

said hand grip means comprising two elongated members positioned on opposite sides of said bulb means;

said elongated members adapted to be pressed inwardly against said bulb means so as to compress said bulb means; and

each of said elongated members being hollow and compressible and being formed from a semi-rigid flexible material, and each of said elongated members including an air release port for releasing air upon compression of said elongated members.

2. The device according to claim 1, wherein said elongated members are integrally attached to said bulb means.

3. The device according to claim 1, wherein said balloon means has a maximum volume of inflation and said bulb means is sized to contain a volume of air sufficient to inflate said balloon means to or below said maximum volume of inflation.

4. The device according to claim 1, wherein said bulb means comprises a hollow compressible member having a definite shape, said hollow compressible member being constructed from a resilient material which causes said hollow compressible member to return to said definite shape after compression.

5. The device according to claim 1, wherein said balloon means comprises a flexible material having elastic properties which inflates into a substantially bell shaped balloon having sloping walls, said sloping walls of said balloon adapted to engage said object upon removal of said device from said body passage.

6. The device according to claim 1, wherein said tubular rod is a catheter.

7. The device according to claim 6, wherein said catheter is formed from a soft and flexible TEFLON material.

8. The device according to claim 1, wherein said tubular rod comprises an encircling wall encompassing an air flow passage, said wall having openings formed therethrough for the flow of said air from said rod and into said balloon means.

9. The device according to claim 8, wherein said rod has an open end and a closed end, said openings being located adjacent said closed end.

10. The device according to claim 1, wherein said tubular rod is soft and flexible.

11. The device according to claim 1, wherein said rod is formed from TEFLON.

12. A device for extracting an object from a body passage, comprising:

an elongated tubular rod;

a compressible bulb means attached to a proximal end of said tubular rod and in fluid communication with said rod for pumping air through said rod;

an inflatable balloon means attached to a distal end of said tubular rod and in fluid communication with said rod for receiving air and inflating; and

hand grips positioned adjacent to and in contact with said bulb means for allowing the gripping of said device, said hand grips comprising two elongated members positioned on opposite sides of said bulb means, said members adapted to be pressed inwardly against said bulb means so as to compress said bulb means, wherein each of said members is hollow and compressible and formed from a semi rigid flexible material and each of said members includes an air release port for releasing air upon compression.

13. The device according to claim 12, wherein said elongated members are integrally attached to said bulb means.
