Abstract

There can be provided a bubble jetting member comprising: a core that is formed of a conductive material; a shell part that is formed of an insulating material, includes an extended section that extends beyond the tip of the core, and is closely adhered at least partially to the core and covers the core; and a space that is formed between the extended section and the tip of the core and has a bubble-jetting port, wherein there is formed on the tip of the extended section a thick portion that is thicker than the rest of the extended section whereby the tip section is not damaged.

First claim

What is claimed is:

1. A gas/liquid jetting member, comprising a bubble-jetting member, and an outside shell part: wherein
the bubble-jetting member comprises:
a core formed of a conductive material and having a tip;
a shell part formed of an insulating material, including an extended section extending beyond the tip of the core, and adheres at least partially to the core and covers the core, the extended section of the shell part having a tip including a bubble-jetting port; and
a space formed between the extended section of the shell part and the tip of the core, and configured to receive a solution;
the tip of the extended section of the shell part has a thick portion that is thicker than the rest of the extended section,
the outside shell part at least partially encloses the shell part covering the core, the outside shell part having a tip section, the outside shell part and the shell part are spaced apart forming a space therebetween,
an end of the outside shell part is connected to the bubble-jetting member by an expansion/contraction member, and
the outside shell part and the bubble-jetting member are configured to be moveable relative to one another by the expansion/contraction member.

2. The gas/liquid jetting member according to claim 1 , wherein a constricted portion is formed on the outside shell part, the constricted portion serving as a guide during relative movement between the outside shell part and the bubble-jetting member.

3. The gas/liquid jetting member according to claim 1 , further comprising:
a counter electrode formed on an outer surface of the shell part or on an inner surface of the outside shell part,
wherein the core of the bubble-jetting member is an electrode, and together with the counter electrical constitutes a pair of electrodes.

4. The gas/liquid jetting member according to claim 1 , wherein the tip section of the outside shell part is formed thicker than the rest of the outside shell part.

5. A localized injection device, comprising the gas/liquid jetting member according to claim 1 .

6. The gas/liquid jetting member according to claim 2 , further comprising:
a counter electrode formed on an outer surface of the shell part or on an inner surface of the outside shell part,
wherein the core of the bubble-jetting member is an electrode, and together with the counter electrical constitutes a pair of electrodes.

7. The gas/liquid jetting member according to claim 2 , wherein the tip section of the outside shell part is formed thicker than the rest of the outside shell part.

8. A localized ablation device, comprising the gas/liquid jetting member according to claim 1 .
