PROBLEM TO BE SOLVED: To provide a medical lead capable of allowing electrodes to have contact with a nerve with appropriate pressure.SOLUTION: A medical lead 1 having a pair of nerve stimulation electrode parts 16 includes: an annular member 3 with a first ring and a second ring formed therein a first elastic lead 12A where one of the nerve stimulation electrode parts 16 is formed at one end and that is arranged in the annular member 3 and a second elastic lead 12B with elastic flexibility where the other one of the nerve stimulation electrode parts 16 is formed at one end and that is put through the second ring. The respective elastic leads 12A, 12B are elastically deformed when they are freely advanced/retreated inside the annular member 3, having contact with the annular member 3. The other one between the first electrode part 17A and the second electrode part 17B is in contact with an axon so as to hold the axon by elastically deforming respective elastic leads 12A, 12B. Thus, conduction is obtained with respect to the axon to thereby allow a nerve stimulation signal to be applicable.COPYRIGHT: (C)2014,JPO&INPIT【課題】適切な圧力で神経に電極を接触させることができる医療用リードを提供すること。【解決手段】一対の神経刺激電極部16を備えた医療用リード1であって、第一環及び第二環が形成された環部材3と、神経刺激電極部16の一方が一端部に形成され環部材3に設けられた第一弾性リード12Aと、神経刺激電極部16の他方が一端部に形成され第二環に挿通され弾性を有する可撓性の第二弾性リード12Bと、を備え、各弾性リード12A,12Bは、環部材3内を自在に進退して環部材3に接することにより弾性変形し、第一電極部17Aと第二電極部17Bとの他方は、各弾性リード12A,12Bが弾性変形されることによって、軸索を挟み込むように軸索に接し、軸索に対して神経刺激信号を印加可能となるように導通する。【選択図】図1
