摘要： A method for percutaneously implanting a medical catheter, such as a gastrostomy feeding tube, and a medical catheter implanting assembly. In one embodiment, the implanting assembly includes a gastrostomy feeding tube, an inner sheath and an outer sheath. The feeding tube has an internal bolster integrally formed at its distal end. The inner sheath includes a bore extending distally from its proximal end to a point prior to its distal end and a transverse window communicating with the bore. The outer sheath includes a proximal end, a distal end and a longitudinal bore. The outer sheath is inserted over the inner sheath, and the feeding tube is inserted into the inner sheath, with the internal bolster being folded and tucked into the window and retained therein by the outer sheath. Movement of the outer sheath relative to the inner sheath to expose the window allows the bolster to decompress.

摘要： A medical catheter assembly including a multi-piece connector. In one embodiment, the medical catheter assembly is a PEG implanting assembly comprising a tubular dilator and a silicone feeding tube having an internal bolster at its rear end. The assembly also comprises a multi-piece connector comprising an inner ring, a fitting and an outer ring. The inner ring has an outer diameter greater than the inner diameter of the feeding tube and is coaxially disposed within the feeding tube by a friction-fit. The fitting comprises a front portion, an intermediate portion and a rear portion, the intermediate portion including a shoulder having an outer diameter greater than the inner diameter of the feeding tube. The front portion of the fitting is inserted through the rear end of the dilator and is secured to the dilator by a plurality of barbs. The shoulder and the rear portion of the fitting are inserted into the feeding tube through its rear end, with the rear portion of the fitting being inserted into the inner ring and secured thereto by mating threads. The outer ring is inserted over the feeding tube and is positioned between the shoulder and the inner ring, the outer ring being sized to securely retain the feeding tube between the outer ring and the inner ring and between the outer ring and the shoulder.

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 vascular access device for infusion of fluids into a patient. The device includes an introducer sheath having one or more side holes and the sheath can be used with a catheter in place through the sheath, with a dilator in place through the sheath, or with the sheath vacant. The device provides for a significant volume of infused fluid to exit the side holes. The side holes allow for the infusion of fluids, such as medications, to be directed to specific patient locations rather than to have the entire volume of infused fluid exit the distal end of the sheath tube.
