A system for surveying an underwater topography includes an ultrasonic sensor array disposable in physical contact with a body of water for generating electrical signals encoding ultrasonic echo responses of underwater objects in the body of water. The sensor array includes a plurality of electromechanical transducers in turn including at least one electroacoustic transducer and one acoustoelectric transducer. The transducers are disposed in a configuration extending in at least two dimensions. An a-c current generator is operatively connected to the electroacoustic transducer for energizing the electroacoustic transducer with an electrical signal of a pre-established ultrasonic frequency. Means are provided which operatively connected to the sensor array for determining locations of the electromechanical transducers relative to one another. A processor or computer is operatively connected to the sensor array for analyzing the electrical signals in accordance with the determined locations of the electromechanical transducers to determine surfaces of objects disposed at least partially in the body of water and for generating a video signal encoding an image of the objects.

A surgical method comprises the steps of (a) piercing an abdominal wall of a patient to form an opening in the wall, (b) inserting a tubular member through the opening, (c) pushing a inert flexible membrane through the tubular member and into a body cavity of the patient, (d) opening the injected membrane from a collapsed configuration into an at least partially opened configuration, (e) juxtaposing the membrane and an internal organ part of the patient, (f) closing the membrane about the body organ part upon juxtaposition of the membrane and the organ part, and (g) drawing the membrane, together with the enclosed organ part, from the patient's body cavity through the tubular member. An associated surgical kit comprises a tubular member insertable through an opening in an abdominal wall of a patient and a flexible membrane disposed in a collapsed configuration at least partially inside the tubular member. An ejection member is provide for pushing the membrane out of the tubular member into an internal body cavity of the patient.

A method for removing a gall bladder comprises the steps of (a) providing a surgical instrument including a flexible loop and a flexible web member connected to said loop to form a capture pocket, the loop defining a mouth opening of the pocket, (b) closing the cystic duct, (c) severing the cystic duct, and (d) passing the loop around a portion of the gall bladder including a closed and severed segment of the cystic duct, thereby enclosing the gall bladder portion in the capture pocket. The method further comprises the steps of (e) severing connective tissue between the gall bladder and the adjacent liver subsequently to the passing of the loop around the bladder, (f) maintaining the gall bladder portion surrounded by the capture pocket during the severing of the connective tissue, and (g) shifting the loop relative to the gall bladder to enclose a greater portion of the gall bladder in the capture pocket upon a severing of some of the connective tissue between the gall bladder and the adjacent liver. The method is adaptable to removing other internal organs, particularly organs which are coupled to adjacent tissue masses via connective tissue.

A method for removing a polyp from inside a patient, comprises the steps of inserting an endoscopic insertion member into a patient, ejecting a cauterization loop from the insertion member, and maneuvering the insertion member and the cauterization loop from outside the patient to place the cauterization loop over a polyp inside the patient. A web member is ejected also from the endoscopic insertion member and is opened from a collapsed configuration to a substantially cup shaped opened configuration having a concave inner surface. The endoscope insertion member and the opened web member are maniipulated from outside the patient to juxtapose the concave inner surface of the web with the polyp, whereupon suction is applied to the web member to form a negative pressure zone between the web member and the polyp, thereby attaching the web member to the polyp in a vacuum seal. Then electrical current is conducted to the cauterization loop to sever the polyp from the patient. The web entrains the severed polyp for removal from the patient.

A lighting device for a surgical operating room comprises a light source for generating visible electromagnetic radiation, at least one light output operatively connected to the light source for emitting and directing the electromagnetic radiation, and an attachment component connected to the light output for removably attaching the light output to a patient. The light output or outlets are mounted to a surgical retractor or, alternatively, to a flexible tube with an adhesive layer for temporarily binding the tube to a skin surface of the patient. The tube is also provided with a form retention element for enabling the tube to be bent to conform to a surgical site. A disposable transparent sheath surrounds the tube or the retractor. Other forms of the lighting device include goosenecks and a frame disposable on the operating table over the patient. In every case, the light source is a cold light source, i. e.

A device for regulating fluid flow in an intravenous line comprises a housing and a flow path system in the housing for defining a plurality of separate flow paths having respective predetermined characteristic flow rates. The housing has an input port connectable to an intravenous line segment extending from an intravenous fluid supply and also has an output port connectable to an intravenous line segment extending to a catheter. The device additionally comprises a selector mounted to the housing and in contact with the flow path system for selectively opening the flow paths to connect the output port to the input port, thereby controlling the amount of fluid or solution flowing through the output intravenous line to a patient.

In a method for closing a ressection in muscular tissues, distal ends of two surgical instruments are juxtaposed to a muscular organ on opposite sides thereof. The organ is compressed between the distal ends of the instruments by moving those distal ends towards one another. Subsequently, a tack is ejected from one instrument through the ressected region of the organ towards the other instrument so that an end of the tack projects beyond the organ. Then, a locking element is positioned on or attached to the projecting end of the tack. The entire operation can be performed laparoscopically, when the ressected organ is the uterus.

A procedure wherein an elongate, at least partially flexible tie member is partially wound about tissues to be closed at a surgical site. Opposite ends of the flexible tie element are entrained by a twisting instrument which has a distal end juxtaposed to the surgical site. The twisting instrument extends out of the patient so that a proximal end of the instrument is manipulable by a surgeon. The surgeon rotates the instrument about a longitudinal axis, thereby twisting the tie member multiple turns about itself. Where the tie member is a wire, the twisting effectively locks the tie member at the surgical site. The tie member may then be severed by a cutters so that the tissues are closed.

A method for reducing intussussception comprises the steps of (a) introducing into a colon a flexible insertion member of an endoscope, (b) moving the insertion member through the colon, (c) using optical components of the endoscope to view contents and surfaces of the colon during the step of moving, (d) upon visualization of a small intestine section folded back into the colon, inflating a balloon at a distal end of the insertion member, the balloon being transparent to optical radiation, (e) pushing the inflated balloon against the intussusscepted small intestine section to force the small intestine section out of the colon, and (f) optically monitoring, via the optical components and through the balloon, the intussusscepted small intestine section and the colon during the step of pushing.

In a method for treating cancer, a tube is inserted into a patient, so that a distal end of the tube is disposed proximately to a tumor. A sclerosing agent such as a concentrated sugar solution is then fed through the tube into the patient and into the tumor. The tube can take the form of a catheter which is introduced into the patient through the patient's vascular system.
