摘要:
An intubation device comprises an imaging conduit including an illumination conduit for delivering illumination to a distal end of the device and an image-receiving conduit for communicating images from the distal end of the device to the proximal end of the device. The device also comprises a flushing conduit for delivery of fluids and/or gases to the distal end of the device. The image conduit and the flushing conduit are attached at the distal end of the device. The distal end of the device can be manipulated by advancing the imaging conduit in an axial direction while maintaining the flushing conduit fixed in place. Furthermore, a length adjustment member is provided for adjusting the extent to which the distal end of the device extends beyond a distal end of an endotracheal tube which is inserted over the imaging and flushing conduits. The illuminating conduit and the image-receiving conduit terminate in separate ports at the distal end of the device. Furthermore, a substantial portion of the device is disposable, so that time consuming sterilization is not necessary.

摘要:
A subcutaneous cardiac device includes two electrodes and a stimulator that generates a pulse to the electrodes. The electrodes are implanted between the skin and the rib cage of the patient and are adapted to generate an electric field corresponding to the pulse, the electric field having a substantially uniform voltage gradient as it passes through the heart. The shapes, sizes, positions and structures of the electrodes are selected to optimize the voltage gradient of the electric field, and to minimize the energy dissipated by the electric field outside the heart. More specifically, the electrodes have contact surfaces that contact the patient tissues, said contact surfaces having a total contact area of less than 100 cm2. In one embodiment, one or both electrodes are physically separated from the stimulator. In another embodiment a unitary housing holds the both electrodes and the stimulator. Sensor circuitry may also includes in the stimulator for detecting intrinsic cardiac activity through the same electrodes.

摘要:
Electrical cardiac therapy devices including lead electrode assemblies for implantation into a patient comprising an electrode having a first face and a second face, and an appendage extending opposite the second face of the electrode, the appendage including an eyelet for securing an insertion device thereto. The assembly may further include an electrode frame assembly to which the appendage may be attached. Alternatively, the appendage may be formed as part of a molded electrode frame assembly. A backing piece may be provided between the electrode frame assembly and the electrode. The frame assembly may cover a portion of a front side of the electrode. Further embodiments include an electrode lead assembly including an appendage with an eyelet and an electrode insertion tool adapted to engage the eyelet. Another embodiment is a treatment kit including an electrode lead assembly having an appendage with an eyelet, an electrode insertion tool adapted to engage the eyelet, and an implantable housing having circuitry for providing electrical cardiac therapy.
