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

Apparatus for performing a minimally-invasive procedure, the apparatus comprising: a shaft having a distal end, a proximal end and a longitudinal axis extending between the distal end and the proximal end, wherein the shaft comprises a flexible portion and an articulating portion, wherein the flexible portion extends distally from the handle assembly and the articulating portion extends distally from the flexible portion, and further wherein the articulating portion is configured to articulate relative to the flexible portion; a handle assembly attached to the proximal end of the shaft; and an end effector attached to the distal end of the shaft; wherein a plurality of articulation cables extends from the handle assembly to the articulating portion, such that when tension is applied to at least one of the plurality of articulation cables, the articulating portion bends relative to the flexible portion of the shaft; wherein the plurality of articulation cables are mounted to the handle assembly such that moving the handle assembly to angle the handle assembly relative to the longitudinal axis of the shaft applies tension to at least one of the plurality of articulation cables, whereby to articulate the articulating portion of the shaft relative to the flexible portion of the shaft.

Apparatus for inverting an elongated flexible tubular sleeve having a proximal end, a distal end and a central lumen extending between the proximal end and the distal end, the apparatus comprising: a hollow tube comprising a proximal end, a distal end and a central lumen extending between the proximal end and the distal end; and an elongated rod movably disposed within the central lumen of the hollow tube, the elongated rod having a proximal end and a distal end, wherein the distal end of the elongated rod comprises a sleeve plug for securing a distal end of an elongated flexible tubular sleeve to the distal end of the hollow tube; wherein, when the elongated flexible tubular sleeve is disposed over the hollow tube, (i) the sleeve plug of the elongated rod is configured to be moved proximally to clamp the distal end of the elongated flexible tubular sleeve to the distal end of the hollow tube, and (ii) the sleeve plug of the elongated rod is configured to be moved distally to release the distal end of the elongated flexible tubular sleeve from the distal end of the hollow tube; and further wherein when the distal end of the elongated flexible tubular sleeve is clamped to the distal end of the hollow tube, the proximal end of the elongated flexible tubular sleeve can be pulled toward the distal end of the hollow tube to invert the elongated flexible tubular sleeve.

Methods and apparatus for inverting a hollow sleeve and thereafter reverting an inverted hollow sleeve

Apparatus for performing a minimally-invasive procedure, the apparatus 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, a first articulating portion and a second articulating portion, wherein the flexible portion extends distally from the handle, the first articulating portion extends distally from the flexible portion, and the second articulating portion extends distally from the first articulating portion; wherein at least one articulation cable extends from the handle to the first articulating portion, such that when tension is applied to the at least one articulation cable, the first articulating portion deflects; wherein a plurality of articulation cables extend from the handle to the second articulating portion, such that when tension is applied to at least one of the plurality of articulation cables, the second articulating portion deflects.
