20100240952 | ENDOSCOPY METHOD AND ENDOSCOPE - With an endoscope including a long, thin inserted portion that is inserted into the body of a patient, securing means for securing the inserted portion to tissue inside the body, the securing means being provided at least at a distal-end portion of the inserted portion, an observation optical system that is provided at the inserted portion and that acquires an image of the tissue, and observation-distance adjusting means for adjusting the distance between the observation optical system and a surface of the tissue, it is possible to attain a stable field of view without having to stop the pulsation or the like of the heart or other tissue. | 09-23-2010 |
20100280539 | ENDOSCOPIC HEART SURGERY METHOD - It is an object to provide an endoscopic heart surgery method with which it is possible to observe an endoscopic image with a stable field of view in the pericardial space. Provided is an endoscopic heart surgery method including an inserting step of inserting an inserted portion of an endoscope into a body from the subxiphoid area and inserting the inserted portion into the pericardial space by penetrating the pericardium in the vicinity of the heart apex; a moving step of advancing the inserted portion toward the base of the heart so that the inserted portion passes through the roof of the pericardial space and is moved toward the heart apex to a treated area in the pericardial space; and an observing step of observing the treated area with the endoscope. | 11-04-2010 |
20100331619 | ENDOSCOPIC HEART SURGERY METHOD - It is an object to provide an endoscopic heart surgery method with which it is possible to observe an endoscopic image with a stable field of view in the pericardial space. Provided is an endoscopic heart surgery method including an inserting step of inserting an inserted portion of an endoscope into a body from the subxiphoid area and inserting the inserted portion into the pericardial space by penetrating the pericardium in the vicinity of the heart apex; a moving step of advancing the inserted portion toward the base of the heart so that the inserted portion passes through the vicinity of the roof of the pericardial space and is moved toward the heart apex to a treated area in the pericardial space; and an observing step of observing the treated area with the endoscope. | 12-30-2010 |
20110071342 | SPACE ENSURING DEVICE - In a pericardioscopic procedure, without providing an endoscope or surgical instrument with special space ensuring means and without unnecessarily dilating the pericardial space, a space necessary for operation of the endoscope or surgical instrument is ensured, so that maneuverability is improved while suppressing complications. Provided is a space ensuring device comprising: a pericardium pressing part for pressing a pericardium from the pericardial space side; a heart pressing part for pressing the surface of a heart from the pericardial space side; and an interconnecting part interconnecting the pericardium pressing part and the heart pressing part, wherein the interconnecting part generates the resilient force enabling expansion against a pressure applied by a pericardium and a heart so as to ensure a space between the pericardium pressing part and the heart pressing part. | 03-24-2011 |
20110190584 | Surgical method and medical device - To perform treatment by readily introducing a device causing minimal invasion even where approach from the body surface is difficult, a medical device includes a guide that is inserted into a lumen; a first balloon at a distal end of the guide, connected to a first flow path extending to a proximal end of the guide; a second balloon on the guide, separated from the first balloon on the proximal-end side and connected to a second flow path extending to the proximal end of the guide; a third balloon extending along the guide from a point between the first balloon and the second balloon to the proximal end and having a port for supplying or discharging fluid at the proximal end; and a cleansing flow path having a discharge port between the first balloon and the second balloon and extending to the proximal end of the guide. | 08-04-2011 |
20110190710 | THERAPEUTIC FLUID INJECTION DEVICE - Therapeutic solution of an amount corresponding to a plurality of injections is injected with the distal end kept inserted in the pericardial cavity via an access port formed to penetrate under the xiphoid process. Provided is a therapeutic-solution injecting device ( | 08-04-2011 |
20120191090 | GUIDE DEVICE - Provided is a guide device including a cylindrical insertion part that is inserted into a body and that opens near a distal end thereof and on a proximal side thereof, a perforating part that is disposed at the distal end of the insertion part and that perforates tissue, a moving part disposed near the distal end of the insertion part so as to be displaceable between a nearby position near the insertion part and a farther position farther away from the insertion part than the nearby position, a biasing mechanism that biases the moving part in a direction away from the insertion part, and a displacement-detecting mechanism that detects displacement of the moving part in the body. | 07-26-2012 |
20130027531 | OPERATION METHOD OF ENDOSCOPE - Disclosed is an operation method of an endoscope, the method comprising: a sheath insertion step of percutaneously inserting at least one sheath in a pericardial cavity of a heart; an insertion step of inserting a rigid scope in the sheath; a view field securing step for securing the view field for a surgical site within the pericardial cavity; a guide step for guiding the rigid scope to the surgical site; and an observation step of observing the surgical site with the rigid scope. | 01-31-2013 |
