Abstract
A system and method for intracranial access is disclosed. In particular, a drill stop is shown providing a way to control the penetration of a drill bit as an access hole into the brain is being formed. Access to a desired location is achieved using a catheter guide device. Also disclosed is a mechanism by which multiple diagnostic and treatment devices can be placed at a desired location in brain tissue without the need for more than one access hole. A drainage catheter is disclosed with a mechanism to allow both drainage and to allow intracranial pressure measurement.
Claims18
An intracranial access device comprising:
- a cranial bolt mountable in an access hole in a skull of a patient;
- a probe platform having a plurality of access ports extending longitudinally through said cranial bolt, said probe platform being attachable to said cranial bolt;
- a first passage extending through said probe platform and sized to allow a catheter access to a cranial space of said skull of said patient;
- a second passage sized to allow a probe access to said cranial space of said skull of said patient;
- said second passage comprising:
- a straight tubular portion positioned through said probe platform and extending distally out of said probe platform;
- said straight tubular portion being substantially parallel to said first passage;
- a curved elbow portion located at a distal end of said straight tubular portion;
- wherein a probe advanced through said second passage passes through said straight tubular region and out said curved elbow portion, such that said probe is directed away from an axis aligned with said straight tubular portion.
An intracranial access device comprising:
- a cranial bolt mountable in an access hole in a skull of a patient;
- a probe platform attachable to said cranial bolt;
- a first passage extending through said probe platform and sized to allow a catheter access to a cranial space of said skull of said patient;
- a second passage sized to allow a probe access to said cranial space of said skull of said patient;
- said second passage comprising:
- a straight tubular portion located through said probe platform and extending distally out of said probe platform;
- said straight tubular portion being substantially parallel to said first passage;
- a curved tubular portion located at and connected with a distal end of said straight tubular portion;
- wherein a probe advanced through said second passage passes through said straight tubular region and out said curved portion, such that said probe is directed away from an axis aligned with said straight tubular portion.
An intracranial access device comprising:
- a cranial bolt mountable in an access hole in a skull of a patient;
- a probe platform attachable to said cranial bolt;
- a first passage extending through said probe platform and sized to allow a catheter access to a cranial space of said skull of said patient;
- a second passage sized to allow a probe access to said cranial space of said skull of said patient;
- said second passage comprising:
- a straight tubular portion located through said probe platform and extending distally out of said probe platform;
- said straight tubular portion being substantially parallel to said first passage;
- a curved tubular portion located at and connected with a distal end of said straight tubular portion;
- wherein a probe advanced through said second passage passes through said straight tubular region and out said curved portion, such that said probe is directed away from an axis aligned with said straight tubular portion in a predetermined direction and into a region of a brain with undisturbed tissue.
