The present disclosure relates to an ostomy method and an implantation method. The ostomy method includes steps of making an incision in the chest to expose the heart, puncturing the left ventricle with a puncture needle, thrusting the puncture needle into the ventricular septum and then into the right ventricle to form a puncture site on the ventricular septum, and dilating the puncture site of the ventricular septum with a dilator to form an opening. The method of the present disclosure can reduce the death rate.

Disclosed are methods and systems for restoring patency across a vascular or non-vascular occlusion. The system may include a retrograde catheter, having a proximal end, a distal end, a first central lumen and a first side port spaced proximally apart from the distal end, the first central lumen extending at least as far as the first side port. An antegrade catheter is also provided, having a proximal end, a distal end, a second central lumen in communication with a second side port spaced proximally apart from the distal end. The catheters may have complementary surface configurations to facilitate alignment of the first and second side ports, so that a wire may be passed out of one of the side ports and into the other side port.

Disclosed are methods and devices for restoring patency across a vascular or non-vascular occlusion. A first catheter having a first side port is configured to advance in a first direction through a vessel from a vascular access site on a first side of the occlusion. A second catheter having a second side port is configured to advance in a second direction through the vessel from a vascular access site on a second side of the occlusion. The catheters may have complementary surface configurations to facilitate alignment of the first and second side ports, so that a wire may be passed through the catheters, out of one of the side ports and into the other side port, to bypass the occlusion.

An endoscopic instrument provides a flexible three-arm snare structure that is adapted to retrieve stones from a human body.

Tortuosity of vessels at or leading to the site of minimally invasive procedures is a problem for conducting such procedures as they increase the difficulty to guide the procedural catheters through tortuous vessels. Methods and apparatus for stabilization of the sheaths and catheters during access, procedures, and withdrawal in these tortuous vessels are disclosed. The apparatus and method for improving access include application of a pull component to the stabilized procedural catheter using a stabilization catheter/wire in addition to a push component from the percutaneous access to make the access easier while enabling use of more flexible catheters and softer wires. These methods and devices address the problems of trauma to the vessels during access, procedure and removal of catheters and wires, improve pushability of softer catheters and wires, and also substantially reduce substantially the procedure time.

Devices used during minimally invasive surgery (sometimes called minimal access surgery or laparoscopic surgery) for implantation and fixation of various cameras, for example, to the human body. An insertable device including a housing divided into two sections, a camera, a sensor, at least two LED lights, a lens flush located above the camera lens to clean a lens of the camera, and a motor for moving the camera in relation to the housing with pan and tilt capabilities. An insertion tool for inserting devices including a cannula, a top housing, and a bottom, wherein the bottom couples with the insertable device. A capture and fixation device for capturing and fixing an insertable device to an internal body cavity wall, the device includes a cannula, at least one slideable clamp device, and a retractable loop. Once the insertable device is positioned, the retractable loop fixes the insertable device to the body cavity wall.

Disclosed is a suture delivery device for endoscopically passing a suture into biological tissue. The device can include two hypodermic needles that can be manipulated via controls on a handle of the device in order to pass a suture from one needle to the other. For example, the device can include a first needle coupled to at least one loop member that, when deployed from the first needle, provides a target through which a second needle of the device can deliver the suture. Once the second needle intersects the loop member, the user can advance a length of suture out through a distal end of the second needle. The loop member can then be retracted into the first needle, thereby grabbing and securing the suture in the process.

This invention concerns the field of ophthalmic surgical instruments used in cataract operations. The invention consists, in particular, to a surgical instrument designed to incorporate the nucleus’s crystalline lens and extract it entirely off the eye. The found consists of a tubular handle rotatable, that operates to an insertion mechanism, to which is connected to an intermediate element from which they take place, through two channels: a cable together joined a collection chamber, adapted to incorporate the nucleus’s crystalline lens; a cursor, suitable for the hermetic closure of the collection chamber and a fixing device, used to weaken the internal fibers of the nucleus. The found allows the elimination of the phase of fragmentation and aspiration of the nucleus’s crystalline lens with the integral removal of the nucleus avoiding micro-injuries or damage to the capsular bag used by ultrasound in the fragmentation phase and the consequent serious intraoperative complications.

An endoscopic cap assembly may include a sleeve and a cap. The cap may include a cap channel extending along an external surface of the cap. The cap may also include an engagement feature extending radially outwardly from the external surface of the cap.

A conduit for creating a passage from a right atrium to a left atrium, through a mitral valve into the left ventricle, and to provide a passage from the left ventricle into the aortic valve. The conduit includes an elongate tubular member having a shaft with a proximal section and a distal loop section at a distal end of the proximal section. The distal loop section includes a proximal curve, a distal curve, a generally straight segment extending between the curves, and a distal tip. The shaft in the distal loop section curves back on itself so that proximal curve is formed by a part of the shaft that is closer along the length of the shaft to the distal tip. The shapes of the proximal and distal curves are selected to direct the distal tip into the mitral valve after it has crossed the inter-atrial septum from the right atrium to the left atrium of the heart, and to orient the distal opening of the distal tip towards the aortic valve when the proximal curve is in the mitral valve and the distal tip is in the left ventricle.
