Stereotactic Access Devices And Methods

摘要

This invention is directed to devices and methods for stereotactic access, and particularly to a frameless stereotactic access device for accessing a body cavity and methods therefor. In general, a stereotactic device may include portions or features for fixing the device to a portion of a patient's body, such as, for example, a skull, such that the device may be generally spatially fixed in relation to the patient's body or part thereof. The stereotactic device may also generally include portions or features for guiding a medical device or other device at a particular trajectory in relation to the patient's body or part thereof.

主权项

1. A stereotactic access device comprising:
a frame body having an opening therethrough and plurality of mounting arms, each of said arms mounting a securing device at an end; a cover body being reversibly attachable to said frame body, said cover body covering said opening in said frame body when attached; and a mounting guide having a guide channel, said mounting guide being retained in said cover body; wherein said plurality of mounting arms forms a stable planar platform with a space underneath said frame body which accommodates curvature of a surface.
