An introducing apparatus includes an elongate tubular sheath having an external diameter small enough to be readily insertable in a selected vein. The sheath has a bore which receives therein a dilator such that a distal end of the dilator projects from out from the distal end of the sheath. A rotatable fastener is rotatably coupled with the dilator, and couples the sheath with the dilator and prevents axial movement therebetween. An anti-rotation member is associated with the dilator and/or the sheath, which prevents the dilator from rotating relative to the sheath as the rotatable fastener is rotated, and also included are means which allow a user to overcome the anti-rotation features without damage to or inadvertent separation the sheath.

Locking catheter introducing system

An electrical lead for sensing electrical activity with the body of the patient and for applying electrical energy to selected body tissue comprises an elongated, flexible polymeric lead body having one or more conductors extending the length thereof, the conductors being connected at their distal end to electrode pads where the pads each comprise a multi-layer thin metallic film structure formed on the surface of the lead body where the overall thickness of the composite electrodes are less than about 5 microns. As such, the electrodes do not adversely impact the ability of the distal end portion of the catheter to flex and conform to tissue structures where sensing is to be taken and therapy delivered via the lead.

The present invention provides an endotracheal breathing tube useful in patient ventilation that has a distally mounted pressure sensor transducer. The endotracheal breathing tube of the present invention has distal and proximal ends with the distal end being configured for emplacement at a preselected area of a patient's trachea and further has multiple interior passages with a first passage useful for providing a flow path for ventilation therapy gas being provided to the ventilated patient and for providing a flow path for removal of exhalation gases. A second passage is utilized by a pair of optical fibers for optical signal transmission to and from a pressure transducer disposed within the second passage near the distal end of the breathing tube. The second passage and the first passage communicate through an opening between the two passages such that the pressure transducer is exposed to the pressure within the distal end of the endotracheal breathing tube, which in turn is substantially equal to the gas pressure outside the endotracheal tube and thus to the gas pressure at the bronchi of the patient. The gas pressure sensed by the pressure transducer and any changes therein are transmitted substantially instantaneously to a ventilator that calculates the instantaneous pressure and provides a real time sensing of the pressure in the patient's lungs and any subsequent changes therein.

Each embodiment of the slitter includes a handle member having an arcuate section joined thereto, a knife blade, a clamp member having a lower arcuate portion, and a hinge for joining the clamp and handle members for hinged movement between catheter clamping and release positions, each of the arcuate section and arcuate portion having transversely opposite facing surface portions for clampingly engaging diametrically opposite surface portions of any one of the number of different outer diameter catheters, and at least one of the arcuate section and arcuate portion having a nose portion for entering between the clamped catheter and the introducer when the introducer is to be removed from the catheter without being moved over the proximal terminal end of the catheter. The knife blade is located radially outwardly of the surfaces that abut against the clamped cather and extends radially outwardly of the nose and is located rearward of the forwardmost part of the nose.
