Temporary or long term implantation device for intracranial probes having hematoma detection apparatus, and method of using device thereof

Abstract

A biopsy needle surrounded by a peel away sheath chemically impregnated with a blood detection composition enabling a user (e.g., a surgeon) to accurately and timely determine the existence of a blood pooling or hematoma when passing an implantable (e.g., deep brain stimulation probes) or non-implantable (e.g., biopsy needle) device into a region of the subject's body (e.g., a brain) to gather tissue for further analysis. A biopsy needle may be provided wherein the needle is tightly surrounded by a peel-away sheath that is chemically impregnated with a blood detection composition. The surgeon may insert the biopsy needle into the subject and peel away the chemically impregnated sheath in order to assess whether or not a blood pooling or hematoma exists, and act immediately to address the blood pooling or hematoma.

What is claimed is: 
     
         1 . A bacterial protein detection device for needles, the device comprising:
 a sheath surrounding a barrel of a needle, the sheath contacting the barrel and having a tubular shape with at least one perforation along an axial direction of the sheath; and   at least two grip protrusions attached to an upper portion of the sheath, such that an external force applied to the at least two grip protrusions initiates a tearing of the at least one perforation along the axial direction of the sheath,   wherein the sheath comprises a film with a visual indicator, such that when the film makes contact with a bacterial protein, the visual indicator of the film changes a color indicating that the bacterial protein has been detected.   
     
     
         2 . A computer-implemented method, the method comprising:
 providing a sheath surrounding a barrel of a needle, the sheath having at least two protrusions disposed at an upper portion, wherein the sheath comprises a film with a visual indicator, such that when the film makes contact with a bacterial protein, the visual indicator of the film changes a color indicating that the bacterial protein has been detected;   inserting the barrel of the needle together with the sheath into a portion of a body; and   applying an external force to the at least two protrusions, while the barrel of the needle remains inserted, such that the external force tears the sheath into two portions.
