Abstract
Methods for performing certain medical procedures wherein a steerable endoluminal punch is used to not only gain access but to create a channel or punch through tissue, thus facilitating follow-up therapeutic procedures. The distal end of the steerable endoluminal punch is controllably articulated by the operator using a control device at the proximal end.
Claims3
A method of placing marker devices in the proximity of a tumor comprising:
- creating a percutaneous stick in the skin proximate the region of the tumor;
- inserting a steerable endoluminal punch into the percutaneous stick and driving the endoluminal punch toward the tumor under radiographic, ultrasound, MRI guidance or the like;
- deploying one or more markers proximate the tumor, wherein the markers possess radiographic density for imaging, or characteristics capable of providing therapeutic benefit to the patient;
- and
- removing the steerable endoluminal punch such that the markers remain in the proximity of the tumor.

A method of achieving vascular access through an inside out procedure comprising:
- creating a percutaneous access point to a femoral vein;
- inserting a steerable endoluminal punch into the percutaneous access point;
- advancing the steerable endoluminal punch through a blockage in the vasculature and to a position cranial to the clavicle;
- articulating the steerable endoluminal punch such that its distal tip is curved and directed toward the surface of the skin;
- advancing a sharp central stylet through the steerable endoluminal punch and out through the skin of the patient;
- advancing the steerable endoluminal punch such that its distal end is exposed outside the patient's skin;
- removing the central stylet;
- inserting a guidewire through the central lumen of the steerable endoluminal punch;
- and
- removing the steerable endoluminal punch leaving the guidewire in place to facilitate reverse access to the patient's vasculature.
