Abstract
Methods and devices are disclosed herein that generally provide protection for devices (e.g., microcatheters) having small tips. Methods and devices are also disclosed herein that generally facilitate use of commercially-available stereotactic systems with devices (e.g., microcatheters) having small tips.
Claims20
A tip protection device, comprising:
- an elongate body having a central lumen extending longitudinally therethrough, the lumen being sized and configured to slidably receive a catheter;
- and
- a locking mechanism configured to selectively maintain the elongate body in a fixed longitudinal position relative to a catheter inserted through the central lumen.
A method of inserting a catheter into a patient, comprising:
- registering a stereotactic system to the patient;
- inserting a catheter having a tip protection device disposed over a distal tip thereof into a working channel of the stereotactic system until a depth stop on the tip protection device prevents further insertion;
- releasing a locking mechanism of the tip protection device and advancing the catheter distally into the patient;
- and
- engaging a locking mechanism of the stereotactic system with the tip protection device, thereby engaging the tip protection device with the catheter to maintain a fixed longitudinal position between the catheter and the stereotactic device.
