Apparatus for performing a minimally-invasive procedure, the apparatus comprising: a shaft having a distal end and a proximal end; a monopolar knife assembly attached to the distal end of the shaft, the monopolar knife assembly comprising a knife; a handle attached to the proximal end of the shaft; wherein the shaft comprises a flexible portion and an articulating portion, wherein the flexible portion extends distally from the handle and the articulating portion extends distally from the flexible portion; wherein at least one articulation cable extends from the handle to the articulating portion, such that when tension is applied to the at least one articulation cable, the articulating portion deflects; wherein an actuation element extends through the shaft from the handle to the knife, such that when the actuation element is moved, the knife is moved; and wherein the actuation element transmits electrical power from the handle to the knife.

Medical instruments for performing minimally-invasive procedures

The invention provides systems, devices, and methods for the delivery, deployment, and positioning of magnetic compression devices at a desired site so as to improve the accuracy of anastomoses creation between tissues, organs, or the like.

Systems, devices, and methods for forming anastomoses

There is disclosed a porous emboli deflector for preventing cerebral emboli while maintaining cerebral blood flow during an endovascular or open surgical procedure. The device prevents the entrance of emboli of a size able to cause stroke (such as greater than 100 microns) from entering either the right or left common carotid arteries, and/or the right or left vertebral arteries by deflecting emboli downstream of these vessels. The device can be placed prior to any manipulation of the heart or aorta allowing maximal protection of the brain during the index procedure. The deflector has a low profile within the aorta which allows sheaths, catheters, or wires used in the index procedure to pass. Also disclosed are methods for insertion and removal of the deflector.

Embolic deflection device

In at least some aspects, an instrument port for introducing an instrument into a surgical site comprises: a port body having: an instrument channel extending through the port body; and a plurality of fluid flush channels each separate from one another and the instrument channel, each extending along a major portion of the port body and in fluid communication with the instrument channel; and a bulb comprising a bulb channel extending through the bulb, the bulb channel aligned with the instrument channel, wherein the bulb channel and instrument channel are configured to receive the instrument.

Instrument port with fluid flush system

An optical bulb for a medical device includes first and second bodies. The first body has a substantially hemispherical distal side. The second body extends from the first body and includes a mechanical connection point at or near the proximal side of the second body. An instrument channel extends through the optical bulb from the proximal side of the second body to the distal side of the first body. An imaging channel extends an aperture defined in the proximal side of the second body and terminates between the proximal and substantially hemispherical distal sides of the first body. The distal end of the imaging channel is substantially hemispherical. The first body is configured and arranged to provide a substantially uniform image path within a field of view of a camera disposed in the imaging channel.

Optical bulb for surgical instrument port

Apparatus for performing a minimally-invasive procedure, the apparatus comprising: a tool comprising: a shaft having a distal end and a proximal end; a handle attached to the proximal end of the shaft; and an end effector attached to the distal end of the shaft; wherein the shaft comprises a flexible portion extending distally from the proximal end of the shaft, and an articulating portion extending proximally from the distal end of the shaft, and wherein the articulating portion comprises a flexible spine; wherein a plurality of articulation cables extend through the shaft from the handle to the flexible spine, such that when tension is applied to at least one of the plurality of articulation cables, the flexible spine bends; wherein a rotatable element extends through the shaft from the handle to the end effector, such that when the rotatable element is rotated, the end effector rotates; and wherein an actuation element extends through the shaft from the handle to the end effector, such that when the actuation element is moved, the end effector is actuated.

An instrument port includes a port body, a bulb disposed at the distal end of the port body, a base body disposed at the proximal end of the port body, a hollow cylindrical body mechanically coupled to the base body, and a plurality of connecting rods disposed parallel to the port body. Each connecting rod includes a distal rod portion that is mechanically coupled to a respective distal-facing exterior surface of a bulb flange and a proximal rod portion that is mechanically coupled to a respective proximal-facing surface of the base body. A spring applies a spring force against the port body to press the port body into the bulb to mechanically secure the bulb to the base body.

Instrument port including optical bulb secured to port body

A gasket for creating a fluid seal in a medical device includes a flexible base, a flexible hollow body, and a multi-leaflet valve. The flexible hollow body extends along an axis from a hole defined in the flexible base. The flexible hollow body is configured to have a relaxed state in which a cross section of the flexible hollow body has a first shape and a compressed state in which the cross section of the flexible hollow body has a second shape. The multi-leaflet valve is disposed in the flexible hollow body. The compressed state causes the multi-leaflet valve to close to increase (a) a first threshold force or a first threshold pressure differential needed to open the multi-leaflet valve in a distal direction and (b) a second threshold force or a second threshold pressure differential needed to open the multi-leaflet valve in a proximal direction.

Gasket with multi-leaflet valve for surgical port apparatus

Apparatus comprising a sleeve adapted to be slid over the exterior of an endoscope, the sleeve having a distal end and a proximal end; an aft balloon secured to the sleeve; a fore balloon movably mounted to the sleeve so that the fore balloon may be advanced relative to the sleeve; and a locking assembly for releasably securing the distal end of the sleeve to the endoscope.

Method and apparatus for manipulating the side wall of a body lumen or body cavity so as to provide increased visualization of the same and/or increased access to the same, and/or for stabilizing instruments relative to the same
