A distal end portion of a tubular member is inserted into the internal organ through a natural body opening. A capture member is ejected from the distal end portion of the tubular member and receives the port element.

Abstract: Improvements in intra-abdominal surgery include a method for removing large chunks of organic or inorganic material from the abdomen through a natural body opening such as the urethra. The technique may be supplemented by laparoscopic procedures.

Abstract: In a method for improving cardiac performance, a compressive cardiac implant is passed through an anterior intraventricular vein of a patient's heart to a position proximate an apex or lower end of a left ventricle of the patient's heart. A distal end portion of the compressive cardiac implant is moved from the anterior intraventricular vein into the patient's left ventricle and thereafter passed through a septum of the patient's heart and into a right ventricle thereof. The distal end portion of the compressive cardiac implant is then engaged with the septum, and the compressive cardiac implant is operated to compress the apex or lower end of the patient's left ventricle so as to reduce the effective volume of the left ventricle.

Abstract: A surgical closure method utilizes a surgical device including an elongate tube, a flexible web member disposed in a collapsed configuration inside the tube, and a push rod disposed at least partially inside the tube for pushing the web member from the tube. A distal end portion of the tube is inserted through an opening or wound in a wall of a hollow body organ. The rod is pushed in a distal direction along the tube to eject the web member from the distal end of the tube. The ejected web member is expanded from the collapsed configuration to an expanded configuration. The expanded web member is placed in contact with the wall of the organ over the opening or wound. Subsequently the expanded web member is attached to the wall of the organ.

Abstract: An endoscopic instrument is inserted into a patient's body to obtain a video image of internal body tissues in an internal space inside the patient's body, a signal encoding the image being transmitted over an electromagnetic signaling link to a remote location beyond a range of direct manual contact with the patient's body and the endoscopic instrument. An artificial opening or perforation is formed in a wall of a hollow internal organ of the patient, the organ communicating with a natural body opening, and a distal end portion of a surgical instrument is inserted through the natural body opening, through the organ and the artificial opening or perforation in the organ wall, and into the internal space. In response to actuator control signals from the remote location via the electromagnetic signaling link, the surgical instrument is automatically actuated to effect a surgical operation on the internal body tissues.

Abstract: A surgical method comprises inserting a distal end portion of a surgical instrument through a natural body opening of a patient into a natural body cavity of the patient, using the surgical instrument to form a temporary artificial opening through a wall of an organ defining the natural body cavity, and providing a surgical device including a membrane, a plurality of tubular members traversing the membrane, and means for attaching the membrane to a wall of an organ so that the tubular members traverse a perforation in the wall. The port device is inserted through the natural body opening into the natural body cavity, and subsequent to the inserting of the port device, the port device is disposed in the artificial opening to keep the same open.

Abstract: In a medical treatment method, magnetic elements are placed into contact with organic tissues of a patient. The magnetic elements are disposed, upon deployment, on opposite sides of tissues or a hole to be closed or collapsed. Owing to magnetic attraction between the magnetic elements, the organic tissues of the patient are held together to constrict tissues or to close or collapse a wound or vessel.

Abstract: A distal end portion of an endoscope insertion member is inserted into a hollow internal organ of a patient, the endoscope insertion member being at least partially encased by a sheath provided with at least one longitudinally extending tubular channel. An incision or perforation is formed in a wall of the organ. The distal end portion of the endoscope insertion member is moved through the incision or perforation into a hollow internal space inside the patient. Thereafter an insufflation gas is delivered through the channel of the endoscope sheath into the internal space.

Abstract: A medical method utilizes a tubular member. The method comprises inserting the tubular member through a patient's mouth into the patient's esophagus so that at least a portion of the tubular member is disposed in the patient's esophagus as a liner, and subsequently inserting flexible endoscopic surgical or diagnostic instruments through the patient's mouth and the tubular member in the esophagus into the patient's stomach. The tubular member is removed from the patient's esophagus after termination of the procedure.

Abstract: A surgical method utilizes an instrument including elongate tube having a lumen, an elongate rod disposed in the lumen, and a screw thread disposed along at least a distal end portion of the rod. The method comprises inserting a distal end portion of the tube into an organ inside patient and thereafter rotating at least the distal end portion of the rod so that the screw thread draws material from the patient in a proximal direction along the lumen.

Abstract: A surgical closure method utilizes a surgical device including an elongate tube, a flexible web member disposed in a collapsed configuration inside the tube, and a push rod disposed at least partially inside the tube for pushing the web member from the tube. A distal end portion of the tube is inserted through an opening or wound in a wall of a hollow body organ. The rod is pushed in a distal direction along the tube to eject the web member from the distal end of the tube. The ejected web member is expanded from the collapsed configuration to an expanded configuration. The expanded web member is placed in contact with the wall of the organ over the opening or wound. Subsequently the expanded web member is attached to the wall of the organ.

Abstract: A surgical method includes inserting a distal end portion of an endoscope into a patient along a given path and inserting a distal end portion of a flexible ultrasonic probe device into the patient along the given path. The ultrasound probe device is operated to generate an image of organic tissue structures internal to the patient. Subsequently, a surgical operation is conducted on the organic tissue structures.

Abstract: In a surgical method, a hollow needle is inserted into a hollow internal organ of a patient through a natural body opening. A wireless scanning apparatus is operated externally of the patient to obtain data as to internal structures of the patient on a side of a wall of the organ opposite the body cavity. A distal tip or free end of the needle is passed through the wall of the organ only upon detecting, via the wireless scanning apparatus, an absence of internal organic tissues of the patient in contact with the wall of the organ on the side of the organ opposite the body cavity. Upon the passing of the distal tip or free end of the needle through the wall of the organ, pressurized CO2 gas is conveyed through the needle into the patient on the side of the wall opposite the body cavity. The needle may be connected to the distal end of an elongate flexible hollow shaft and an endoscope may be optionally used to view the needle deployment procedure.

Abstract: A trans-vascular surgical method includes forming an artificial opening in a blood vessel of a patient's vascular system at a substantially predetermined location and moving a distal end portion of a medical instrument through at least a section of the patient's vascular system and through the artificial opening. A surgical port device is disposed inside the blood vessel to inhibit blood from exiting the patient's vascular system through the artificial opening while permitting extension of the distal end portion of the medical instrument through the artificial opening. After moving the distal end portion of the medical instrument through the artificial opening, the medical instrument is operated to perform a medical procedure operation inside the patient.
