Abstract
A device for treating hemorrhoids is formed from a hollow member having integral insertion and collar portions. Controlling means located within the member and running from the collar to at least partially the length of the insertion portion serve to control the maximum transverse section of the device. Reduction of the cross section eases insertion and extraction of the device. Release of the controlling means allows the device to resiliently return to its normal condition.
Claims13
A medical device for the treatment of hemorrhoids comprising:
- a substantially hollow insertable member having a flexible, resilient wall with an insertable tip at one end and a neck opposite to said tip toward the opposite end with said insertable tip having a transverse section along its length which is substantially circular and a longitudinal section which is substantially parabolic in the region of said tip flaring to provide a maximum transverse diameter adjacent to the midpoint between the tip and the neck and progressively diminishing from the point of maximum transverse diameter to provide a minimum transverse diameter at the neck;
- a substantially hollow collar having a flexible, resilient wall formed into a substantially truncated conical shape with its minimum transverse diameter attached to the neck of said insertable section and its maximum transverse diameter farthest from the tip of said insertable tip;
- controlling means extending from said collar to at least partially down the length of said insertable section for selecting the transverse diameter of said insertable section by manipulating said collar single-handedly using the thumb and forefinger causing the walls of said insertable section to be drawn inwardly.
