Abstract
A system for use in connection with a blood vessel includes a proximal section including a control system and a distal section. The distal section has connected thereto an application device configure to apply one or more ligating clips to the blood vessel to mechanically ligate the blood vessel. The application system is in connection with the control system. The distal section further has connected thereto a cutting device which is configured to mechanically cut tissue, including the blood vessel (for example, after compressive force is applied to the vessel via one or the one or more ligating clips).
Claims20
A system for use in connection with a blood vessel, comprising:
- a proximal section comprising a control system,
- a distal section,
- an application device in connection with the distal section to apply one or more ligating clips to the blood vessel to mechanically ligate the blood vessel, the application system being in connection with the control system, and
- a cutting device in operative connection with the distal section, the cutting device being configured to mechanically cut tissue including the blood vessel.
A method of cutting and ligating a blood vessel, comprising:
- causing a ligating clip to be applied to and mechanically compressed around the blood vessel using an application device of a system, the system comprising a proximal section and a distal section, the application device being in connection with the distal section, and
- after causing the ligating clip to be applied to and mechanically compressed around the blood vessel, mechanically cutting the blood vessel at a predetermined position using a cutting device of the system in connection with the distal section.
A clip for use in connection with a blood vessel, comprising:
- an opening via which the clip can be placed around the blood vessel;
- one or more cutting edges positioned to be brought into contact with and cut through tissue of the blood vessel upon compression of the clip around the blood vessel;
- and
- one or more ligating sections positioned to be brought into contact with and ligate tissue of the blood vessel upon compression of the clip around the blood vessel, whereby the clip is adapted to both cut through and ligate the blood vessel upon compression of the clip around the blood vessel.
