An ultrasonic surgical instrument that is configured to permit selective positioning of the relative distance between an end effector for cutting and coagulating tissue and a power actuation switch that is carried by the instrument for selectively energizing the end effector. In one instance, the end effector is able to change position relative to the actuation switch, alternatively, the actuation switch moves relative to the end effector, and still further, both the end effector and the actuation switch are capable of moving relative to each other.

A device for use as a portal in percutaneous minimally invasive surgery performed within a patient's body cavity includes a first elongated hollow tube having a length adjusted with a self-contained mechanism. The first elongated tube includes an inner hollow tube and an outer hollow tube and the inner tube is adapted to slide within the outer tube thereby providing the self-contained length adjusting mechanism. This length-adjustment feature is advantageous for percutaneous access surgery in any body cavity. Two or more elongated tubes with adjustable lengths can be placed into two or more adjacent body cavities, respectively. Paths are opened within the tissue areas between the two or more body cavities, and are used to transfer devices and tools between the adjacent body cavities. This system of two or more elongated tubes with adjustable lengths is particularly advantageous in percutaneous minimally invasive spinal surgeries, and provides the benefits of minimizing long incisions, recovery time and post-operative complications.

A two-stage or component-based valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve comprises a support structure that is deployed at a treatment site. The prosthetic valve further comprises a valve member configured to be quickly connected to the support structure. The support structure may take the form of a stent that is expanded at the site of a native valve. If desired, the native leaflets may remain and the stent may be used to hold the native valve open. In this case, the stent may be balloon expandable and configured to resist the powerful recoil force of the native leaflets. The support structure is provided with a coupling means for attachment to the valve member, thereby fixing the position of the valve member in the body. The valve member may be a non-expandable type, or may be expandable from a compressed state to an expanded state. The system is particularly suited for rapid deployment of heart valves in a conventional open-heart surgical environment.

The projections may be finely configured and distributed so as to form a knurled surface on the head portion.

A device for correcting and stabilizing a curvature of a spinal column by anterior fusion including at least two brace holders (1-5), each adapted to be arranged against an associated vertebral body (7-11) in the spinal column. The device also includes a securing means (6, 6') for securing the respective brace holders (1-5) on said vertebral body (7-11), and at least one elongate brace (12), which is adapted to extend through and between said brace holders (1-5) along the extent of the spinal column and be locked thereto. The brace (12) is plate-shaped, and the brace holder (1-5) is designed to support the brace (12) in such a manner that a first flat side of the brace (12) faces the abutment surface of the brace holder (1-5) on said vertebral body (7-11), whereby the brace (12) is deformable in only one geometric plane during mounting in the brace holder (1-5) and during correction. In a method for contacting and stabilizing the curvature, the brace (12) is arranged to extend through the brace holders (1-5), such that the brace (12) is deformed to substantially follow the curvature. The brace is locked in at least one first brace holder (1), whereupon the spinal column, vertebra by vertebra, is corrected while the brace (12) is gradually clamped and locked in the brace holders (1-5).

An apparatus for ligating living tissues comprises an introducing tube capable of being inserted into a living body cavity, a manipulating wire movably inserted into the introducing tube, and clips for ligating living tissues, the clips being arranged in the introducing tube. The introducing tube has a plurality of tube channels. A plurality of clips are arranged in series in the tube channel, and a manipulating wire engaged with the clips is arranged at the other tube channel.

A personal surgical center embodied as a general purpose computer (e.g. laptop) with wireless technology for monitoring the operation of an independent surgical center and/or handheld instruments. The computer tracks procedures in the operating room and instruments used during those procedures, and accounts for billing, supply management, and payment options. The monitoring of the instruments used during the surgery is conducted by the personal surgical center while actual control of the settings of those instruments is via the independent surgical center or via controls included in the instruments themselves. The monitored information is stored in a log file which is then transmitted to a hospital server for generating reports, inventory control, billing, and the like. Other information generated during the procedure (e.g. doctor notes) is also stored in the log file. The personal surgical center may also access the hospital server or local data storage device for retrieving a surgeon's specific surgery parameters, obtaining patient files, and the like.
