Abstract
A device selected from microelectrode, temperature sensor, optical sensor, optical fibre, temperature control element, and microdialysis probe for insertion into soft tissue comprises a body with a distal terminal section and a layer of an agent such as gelatin capable of forming a gel with aqueous body fluid on the terminal section. The terminal section and the gel-forming layer have a temperature of more than 30° C. below body temperature during a period of time prior and up to insertion. Also disclosed is method of insertion, an insertion assembly and a use of the device.
Claims37
A device for insertion into soft tissue, in particular nervous or endocrine tissue, selected from microelectrode, temperature sensor, optical sensor, optical fibre, temperature control element, microdialysis probe, comprising:
- a device body extending between a distal end and a proximal end comprising a distal terminal section extending from the distal end in a proximal direction;
- and
- a layer of a material capable of forming a gel in contact with aqueous body fluid covering the distal terminal section;
- wherein the distal terminal section, and the layer of material capable of forming a gel in contact with aqueous body fluid have a temperature substantially below body temperature during a period of time prior and up to insertion;
- and
- wherein the distal terminal section, and the layer of material capable of forming a gel in contact with aqueous body fluid are covered by a layer of ice.
A combination of surgical cannula or needle and needle channel insert for inserting a device of the invention into soft tissue, comprising a means capable of stopping the distal displacement of the insert in the channel to provide the combination with a joint distal point comprising co-planar or co-curved faces.
