摘要:
The end of the elongated tubular element of the appliance that is designed to be inserted into a body cavity or vessel is formed entirely of soft, compliant material. That end carries an inflatable balloon formed in its fully inflated shape. The balloon is inflated to a predetermined low pressure level to prevent pressure necrosis in the adjacent tissue. A method and apparatus for introducing the soft end of the appliance into the body cavity are also provided. The introducer apparatus includes rigid core surrounded by a soft, compliant sleeve. The sleeve extends beyond the rigid core to form an invertable section. The soft end of the appliance is situated adjacent the apparatus, the balloon is wrapped around the apparatus, and the sleeve section is inverted over the appliance, compressing the balloon and forming a soft, rounded insertion tip. The unit is then introduced into the body cavity. After the appliance is separated from the apparatus, the apparatus is withdrawn.

The present invention is directed to a speculum assembly for single-use in colon lavage therapy. The speculum assembly comprises a tubular body to which a tubing-set is attached. The tubular body has a leading end, a middle portion, and a trailing end. The leading end has a tapering body transitioning into a tip, a scallop opening adjacent to the tip, and at least one annular rib about the tubular body, positioned between the scallop opening and the middle portion. The middle portion has a flange. The flange is in communication with a portion of an irrigation tube. The trailing end of the tubular body comprises a handle that selectively retains a portion of the irrigation tube and attaches to a portion of a waste hose, elements of the tubing set.

An apparatus for locating rectovaginal fistulas, including a cannula of a predetermined length, open-ended on its first end having an inflatable balloon portion on its closed second end; the first end of the cannula further comprising a cone portion along its length to seal up against the exterior wall entrance to the rectum, after the second end of the cannula has been inserted into a patient's rectum; a fluid line is positioned within the cannula space for inflating the balloon after the cannula is in place in the rectum to seal the distal end of the rectum passage; a plurality of openings are provided along the wall of the cannula between the balloon and the cone at the first end of the cannula; a colored gel or other fluid insertable into the cannula to the extent that the gel or other fluid escapes the cannula through the openings and enters the void between the cannula and the wall of the rectum, with sufficient gel or other fluid entering the void so that gel or fluid would seep into any fistulas present and would be visually identifiable in the vagina for treatment.

A sphincter valve for controlling the flow of fluid through a fluid delivery line has a body molded of a unitary piece of substantially flexible silicone material. The body is formed with an outer shell, and interior tube disposed within said outer shell, an end portion, and a pressure chamber defined between the outer shell and the interior tube. A separate end cap is secured to and closes the end of the body opposite the end portion thereof and a central passageway extends through the interior tube and through the ends of the valve. In use, the valve is spliced in a fluid delivery line and the pressure chamber is coupled to a source of selectively deliverable pressurized air. When pressurized air is forced into the pressure chamber, the inward force created by the pressure collapses the interior tube onto itself shutting off flow through the valve.

A dissolvable tip 20 or 40 for a colon hydrotherapy speculum system 100 that replaces the function of an obturator. The dissolvable tip 20 or 40 is made of a body of dissolvable material wherein a surface of the tip 20 or 40 is inserted and snugly fit into an inserting end 17 of a speculum 10 while another surface of the tip 20 or 40 with the speculum 10 is inserted into the anal, rectal, or colon canal 91 of a patient 90. The dissolvable tip 20 or 40 is held at the inserting end 17 of the speculum 10. One embodiment of the present invention discloses the dissolvable tip 20 as a pill shaped and egg shaped tip. Another embodiment of the present invention discloses the dissolvable tip 40 as similar in shape to dissolvable tip 20, but the dissolvable tip 40 further has a circumferential bulge 44 in its body wherein the circumferential bulge 44 has an edge that contacts the perimeter of the inserting end 17 of speculum 10 to allow a further snug attachment between the dissolvable tip 40 and the speculum 10. The colon hydrotherapy machine 130 of system 100 allows inlet washing fluid to flow from the machine 130 through the hose 110 and speculum 10 and to the tip 20 or 40 so that the tip 20 or 40 dissolves into the patient and inlet washing fluid flows into a colon area of the patient that is to be cleaned. Outlet fluid is able to flow from the colon area, through outlet end 18 of speculum 10, and through outlet hose 120. The material used to make the dissolvable tip 20 or 40 can have the further properties or characteristics of a deodorizer or a disinfectant or can function as a laxative or a type of medicine that helps the colon or rectal area of a patient 90. Tips 20 and 40 can also be made to be a natural product (i.e. made of herbs and other such components) that can be easily dissolved within the patient without any serious risks or hazards to the patient.
摘要:
A process for colonic lavage including the steps of directing pressure water of a predetermined volume and temperature through a filter for removing particulate contaminants and through a field of ultraviolet radiation and thence to irrigate a patient's colon to remove extraneous material from the colon for selective laboratory examination if required.

A device for cleansing the colon includes an elastic housing with an oval-shaped end and provided with an aspiration channel and a discharge channel isolated from each other, each channel having its own outlet port in the end of the housing. An endoscope is built into the aspiration channel and is provided with a transparent balloon on its working portion, while the discharge channel accommodates an open-end capillary tube whose open end is brought outwards through the end of the housing, the other end of the tube being connected to a pressure measurement instrument.

The present invention relates, in various embodiments, to formulations comprising hydrocortisone and silicon dioxide. In additional embodiments, the invention relates to suppositories comprising hydrocortisone and silicon dioxide. The formulations of the present invention are useful for administration to patients who have gastrointestinal diseases and disorders such as, for example, inflammatory bowel disease.

Various embodiments disclosed relate to drug-coated balloon catheters for treating, preventing, or reducing the recurrence of a stricture and/or cancer, or for treating benign prostatic hyperplasia (BPH), in a non-vascular body lumen and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent. In some embodiments, the balloon catheter includes a length-control mechanism which stretches and elongates the balloon when it is in a deflated state, giving the balloon a smaller cross-sectional deflated profile for tracking through the body lumen and for removal after treatment.
