摘要： A low profile adaptor for use with a medical catheter. In one embodiment, the adaptor comprises a lower connector portion, an upper connector portion and a valve. The lower connector portion comprises a tubular portion and an annular portion, the annular portion radially surrounding the tubular portion along an intermediate length thereof. A helical thread is formed on the inside surface of the tubular portion. A circular lip projects upwardly a short distance from the top surface of the annular portion. The upper connector portion comprises a tubular section adapted for insertion into the tubular portion of the lower connector portion. An external helical thread is formed on the tubular section of the upper connector portion for mating engagement with the thread on the interior of the tubular portion of the lower connector portion. The upper connector portion also includes an annular base. The top of the base is shaped to include a cavity for receiving the valve, the cavity being in fluid communication with the tubular section. A double-walled circular lip is formed on the bottom of the base, the double-walled lip being sized and shaped to define a groove adapted to matingly receive the lip on the upper connector portion. In use, the lower connector portion is inserted into the end of a catheter, and the tubular section of the upper connector portion is screwed into the tubular portion of the lower connector, with the catheter being ensnared between the lips of the upper and lower connector portions.

摘要： 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.

摘要： Low profile adaptor for use with a medical catheter, such as a gastrostomy feeding tube. In a preferred embodiment, the adaptor comprises a body having a lower portion and an upper portion. A first channel is provided in the lower portion, and a second channel is provided in the upper portion, the first and second channels being perpendicular to and in fluid communication with one another. A generally cylindrical stem is coaxially positioned within the second channel, the stem being rotatably mounted about its longitudinal axis. The stem is hollow and has an open front end, a closed rear end and a hole in its side wall, the hole being rotatably alignable with the first channel. To facilitate rotational alignment of the hole with the first channel, a stop is formed on the exterior of the stem, the stop being engageable with a surface positioned within the second channel. The front end of the stem is recessed relative to the front end of the second channel to prevent unwanted rotation of the stem. Rotation of the stem from a closed position to an open position is achieved by screwing a syringe onto the front end of the stem. The proximal end of the gastrostomy feeding tube is inserted over the lower portion of the body and is secured thereto with a nut.

摘要： A medical catheter assembly and method of using the same. In one embodiment, the assembly comprises a gastrostomy feeding tube having a proximal end, a distal end and a longitudinal bore, the distal end being shaped to include an internal bolster, the internal bolster having an anchoring state and a non-anchoring state. A suture extends from the internal bolster through the longitudinal bore to exit the tube at its proximal end, proximal displacement of the suture maintaining the internal bolster in its anchoring state. A protective sleeve made of a rigid material is removably insertable into the tube through its proximal end, the suture being inserted through the protective sleeve. The protective sleeve, when inserted into the tube, serves to protect the suture from being cut when the tube is cut to a desired length after having been implanted in a patient.

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 alignable with the longitudinal bore and correspondingly dimensioned and a narrow region alignable with the longitudinal bore. In use, a medical catheter is inserted up through the base portion and the sleeve portion, including the transverse opening of the clamp situated within the sleeve, and is then inverted over the top edge of the sleeve. The cap is then threadingly 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. By aligning the wide region or the narrow region of the clamp with the longitudinal bore of the sleeve, one can open or close, respectively, the catheter to the passage of fluids therethrough.
