Guide for placement of catheter into brain and a method of utilizing the same
View Patent ↗The subject matter discloses a method and apparatus for detecting an environment within a body comprising a stylet and a catheter capable of being inserted into the body and a bio-sensing module for detecting a predefined material within the body, upon insertion of the stylet and catheter with close proximity to the predefined material. The predefined material may be beta-transferrin, and the apparatus may comprise a transmitter and an indication unit for transmitting data related to the presence of the predefined material in the body.
1. An ultrasound probe adapted for guiding the placement of a catheter, comprising:
an ultrasound imaging probe;
a catheter guiding apparatus;
a plurality of catheter holding members for holding the catheter guiding apparatus;
a plate having fastening elements connected thereto for fastening the ultrasound imaging probe to the ultrasound probe;
wherein said plate further affixes said plurality of catheter holding members;
wherein the ultrasound probe and the catheter guiding apparatus are positioned on different sides of the plate.
2. The ultrasound probe according to claim 1 , further comprising a Doppler ultrasound transducer and a signal processing circuit, for sensing signals representative of blood flow within a patient.
3. The ultrasound probe according to claim 1 , wherein the catheter guiding apparatus comprises a tubular unit having an opening and a curved cross-sectional area dimensioned to receive a catheter of a predetermined diameter.
4. A method of accurately inserting a catheter or trocar into a patient's brain, the method comprising:
mounting a catheter guiding apparatus on an ultrasound probe to form an ultrasound probe-catheter guiding complex, a plurality of catheter holding members for holding the catheter guiding apparatus;
wherein the catheter guiding apparatus comprises a plate having fastening elements connected thereto for fastening the ultrasound imaging probe to the ultrasound probe;
wherein said plate further affixes said plurality of catheter holding members;
wherein the ultrasound probe and the catheter guiding apparatus are positioned on different sides of the plate;
inserting a catheter or a trocar through the mounted catheter guiding apparatus;
determining a trajectory using the ultrasound imaging probe;
fixing said ultrasound probe-catheter guiding complex in space; and,
inserting the catheter or a trocar through the mounted catheter guiding apparatus into the patient's brain through an opening in the patient's skull, using the determined trajectory.
