However, the intracardic operations or the aortic operations have not been established like this less invasive procedures, because the enough view is not gotten with the filled blood. Usage of the heart-lung machine is still indispensable for these operations now, and the incidence of postoperative complications is also high. An epoch-making treatment like as stentgrafting custody is developed, and there are several problems to be.solved. In this report, we developed the devices for less-invasive intracardiac and aortic surgeries. These basic experiments were performed by pigs.\n1.Development of the angioscope\nThe improvement was added to the angioscope as follows; The balloon made of the urethane was inflated by CO_2. The satisfied view was obtained.. No damage in the aorta was caused because of the balloon expansion. The thrombosis was not detected by this procedure.\n2.Development of the catheter with stapler\nThe catheter type stapler was designed. The anastmosis between the artificial graft and the aorta was performed easily and safely.\n3.Development of catheter type post-dolatation device\nThe dilatation devise was made of metallic wire instead of the balloon. There was no significant aortic damage by the post-dilatation. The fixation between the artificial graft and the aorta was increased.\n4.Intracardic operation\nBy ultrasonic CCD camera, the intracardiac structures were observed. Experimental ASD closure was tried. The observation by the ultrasonic CCD camera was easil and clearly. However, the device size is too large, and it is difficult to use this device clinically now.\n5.Aortic surgery using new devices\nThe devices developed by this experiment 1, 2, and 2 was totally examined. Under angioscopic observation, the stentgraft deployment was smoothly. Furthermore, the staplers were effective.\n[Conclusion]In this series, The attractive devices for cardiovascular surgery were developed. Though there are several problems for clinical trial, the technical innovation will solve in future.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:14370406, 研究期間(年度):2002 – 2003","subitem_description_type":"Other"},{"subitem_description":"出典：「超音波CCDカメラを用いた完全鏡視下心腔内・大血管内手術systemの開発」研究成果報告書　課題番号14370406\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所））\n（https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-14370406/143704062003kenkyu_seika_hokoku_gaiyo/)を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学医学系研究科","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00063471","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/search/?kw=60242492"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/search/?kw=60242492","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-14370406/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-14370406/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-14370406/143704062003kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-14370406/143704062003kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-10-22"}],"displaytype":"detail","filename":"ME-PR-WATANABE-G-kaken 2006-2p.pdf","filesize":[{"value":"104.9 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"ME-PR-WATANABE-G-kaken 2006-2p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/57201/files/ME-PR-WATANABE-G-kaken 2006-2p.pdf"},"version_id":"14e18134-a0d4-4b9b-ae46-9e66f7f9fb7e"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"超音波CCDカメラを用いた完全鏡視下心腔内・大血管内手術systemの開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"超音波CCDカメラを用いた完全鏡視下心腔内・大血管内手術systemの開発"},{"subitem_title":"Development of a new thoracoswpic cardiovascular surgicall systems with CCD camera","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2830"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-10-22"},"publish_date":"2021-10-22","publish_status":"0","recid":"57201","relation_version_is_last":true,"title":["超音波CCDカメラを用いた完全鏡視下心腔内・大血管内手術systemの開発"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T14:36:38.758753+00:00"}
