Medical catheter assembly including a removable inner sleeve and method of using the same

A medical catheter assembly including a removable inner sleeve. In one embodiment, the assembly is a low profile percutaneous endoscopic gastrostomy (PEG) device and comprises a body, a clamp, a feeding tube, a cap and an inner sleeve assembly. The body includes a base portion and a sleeve portion, the base portion being dimensioned to engage the skin of a patient and having a transverse bore, the sleeve portion extending upwardly from the base portion and having a longitudinal slot aligned with the transverse bore and a transverse slot intersecting the longitudinal bore. The clamp, which is slidably mounted on the base portion and across the transverse slot of the sleeve, comprises a plate having a transverse opening. The transverse opening has a wide region and a narrow region, the two regions being alternately alignable with the longitudinal bore to open and to close, respectively, the feeding tube. The feeding tube has a distal end adapted to be anchored to the inside of a patient and a proximal end inserted up through the base portion and the sleeve portion, including the transverse opening of the clamp situated within the sleeve, and then inverted over the top edge of the sleeve. The cap is then mounted on top of the sleeve so as to secure the inverted end of the catheter to the exterior of the sleeve. The cap is provided with an opening through which access to the catheter may be gained. An inner sleeve, sized to engage the inside surface of the feeding tube, is removably inserted through the cap and the feeding tube, the inner sleeve having a proximal end to which a tubular fitting is secured. Food and / or medications are dispensed to the patient through the fitting and the inner sleeve and, in this manner, prevent clogging of the feeding tube.

Dendritic Polymers With Enhanced Amplification and Interior Functionality

Dendritic polymers with enhanced amplification and interior functionality are disclosed. These dendritic polymers are made by use of fast, reactive ring-opening chemistry (or other fast reactions) combined with the use of branch cell reagents in a controlled way to rapidly and precisely build dendritic structures, generation by generation, with cleaner chemistry, often single products, lower excesses of reagents, lower levels of dilution, higher capacity method, more easily scaled to commercial dimensions, new ranges of materials, and lower cost. The dendritic compositions prepared have novel internal functionality, greater stability (e.g., thermal stability and less or no reverse Michael's reaction), and reach encapsulation surface densities at lower generations. Unexpectedly, these reactions of polyfunctional branch cell reagents with polyfunctional cores do not create cross-linked materials. Such dendritic polymers are useful as demulsifiers for oil / water emulsions, wet strength agents in the manufacture of paper, proton scavengers, polymers, nanoscale monomers, calibration standards for electron microscopy, making size selective membranes, and agents for modifying viscosity in aqueous formulations such as paint. When these dendritic polymers have a carried material associated with their surface and / or interior, then these dendritic polymers have additional properties for carrying materials due to the unique characteristics of the dendritic polymer, such as for drug delivery, transfection, and diagnostics.

Submerged gas evaporators and reactors

A submerged gas processor in the form of an evaporator or a submerged gas reactor includes a vessel, a gas delivery tube partially disposed within the vessel to deliver a gas into the vessel and a process fluid inlet that provides a process fluid to the vessel at a rate sufficient to maintain a controlled constant level of fluid within the vessel. A weir is disposed within the vessel adjacent the gas delivery tube to form a first fluid circulation path between a first weir end and a wall of the vessel and a second fluid circulation path between a second weir end and an upper end of the vessel. During operation, gas introduced through the tube mixes with the process fluid and the combined gas and fluid flow at a high rate with a high degree of turbulence along the first and second circulation paths defined around the weir, thereby promoting vigorous mixing and intimate contact between the gas and the process fluid. This turbulent flow develops a significant amount of interfacial surface area between the gas and the process fluid resulting in a reduction of the required residence time of the gas within the process fluid to; achieve thermal equilibrium and / or to drive chemical reactions to completion, all of which leads to a more efficient and complete evaporation, chemical reaction, or combined evaporation and chemical reaction process.

Intraocular lens with distortion free valve

The invention provides a medical device and method to reduce the occurrence of pseudophakic pupillary block following implantation of an intraocular lens. The device includes an intraocular lens configured with channels traversing through the surfaces of the lens optic. The invention includes special edge angulations and locations in the optic zone that eliminate optical distortion from channels. The channels perform as valves configured to allow flow of a patient's aqueous humor from one surface of the lens through to the other surface of the lens, thereby preventing fluid pressure from building up in a patient's eye.

Dispensing valve

A valve assembly can automatically dispense aerosol content from an aerosol container at predetermined intervals without the use of electric power. A diaphragm at least partially defines an accumulation chamber that receives gas propellant from a portion of the can during an accumulation phase. Once the internal pressure of the accumulation chamber reaches a predetermined threshold, the diaphragm moves, carrying with it a seal so as to unseal an outlet channel, and thereby initiate a spray burst of the main active chemical. The diaphragm assumes its original position when the pressure within the accumulation chamber falls below a threshold pressure.
