    摘要： A system for accessing a desired site within a patient's body includes a cannula defining an inner lumen that opens into a longitudinally extending side aperture formed in the side of the cannula, near its distal end. An electrosurgical stylet slidably fits inside the inner lumen. At the distal end of the stylet is an electrosurgical electrode capable of ablating tissue and permitting advancement of the system into a patient's body. The electrode, in an expanded deployed configuration, can be wider than the maximum transverse dimension of the cannula, but it may be deflected toward the center of the stylet so that the electrode fits within the inner lumen of the cannula, permitting the stylet to be inserted and removed through the cannula. An elongate guide tube having a central axial bore which communicates with an orifice in the side of the guide tube can be inserted into the inner lumen of the cannula such that the guide tube orifice coincides with the longitudinally extending side aperature of the cannula. In use, the stylet with the cannula disposed about it is advanced into the patient's tissue, using electrosurgical ablation, until the side aperture of the cannula is disposed adjacent a desired site within the patient. The stylet can then be withdrawn from the cannula providing access through the inner lumen of the cannula to the tissue at the desired site.

    摘要： The present invention is a device for insertion into a human or animal body, in a preferred embodiment a perfusion guidewire capable of delivering perfusion fluids to a vascular site while at the same time exhibiting handling characteristics associated with existing non-perfusion guidewires. Preferred embodiments include a perfusion guidewire which closely matches the dimensions and physical characteristics of standard guidewires. Preferred embodiments also permit high pressure perfusion of oxygen-supersaturated solutions, and include a diffuser segment which divides the flow and reduces fluid velocity, thereby providing an atraumatic, non-cavitating, bubble-free delivery to the patient. The invention also encompasses the attachment of a core wire within a tubular housing to provide superior characteristics to such guidewires, balloon catheters and similar devices.
