20180008278 · 2018-01-11 ·

The present invention relates to a device and method for making sclerosing foam, which is useful in the treatment of varicose veins and other venous conditions. The device comprises a continuous pathway that is at least partly formed of flexible or compressible material and that comprises a foam generating structure within the continuous pathway; the foam generating structure being formed of two or more elements, wherein each element defines at least one passageway of cross sectional area 1 μm2 to 10 mm2 and said two or more elements being arranged in series; a port which allows introduction of material into or extraction of material out of the continuous pathway; and a liquid pathway that is at least partly formed of flexible or compressible material and is arranged to deliver liquid into the foam generating structure between a first and second element of the foam generating structure.

ENDOSCOPIC SURGICAL DEVICE AND OVERTUBE
20180008309 · 2018-01-11 · ·

This endoscopic surgical device includes: an endoscope; a treatment tool; and a mantle tube. The inside of the mantle tube is partitioned by a partition wall member provided with an endoscope guide groove and a treatment-tool guide groove, to form an endoscope insertion passage and a treatment-tool insertion passage. An endoscope fixation tool and a treatment-tool fixation tool are respectively disposed inside the endoscope guide groove and the treatment-tool guide groove. The endoscope fixation tool advances and retracts in conjunction with the endoscope insertion part inserted through the endoscope insertion passage. The treatment-tool fixation tool moves in conjunction with the treatment-tool insertion part inserted through the treatment-tool insertion passage. When a coupling ring externally fitted to the partition wall member interlocks the endoscope fixation tool with the treatment-tool fixation tool, the endoscope insertion part also moves in conjunction with the advancement and retraction of the treatment-tool insertion part.

Ultrasonic sealing algorithm with temperature control

A method of ultrasonic sealing includes activating an ultrasonic blade temperature sensing, measuring a first resonant frequency of an ultrasonic electromechanical system that includes a transducer coupled to the blade via a waveguide, making a first comparison between the measured first resonant frequency and a first predetermined resonant frequency, and adjusting a power level applied to the transducer based on the first comparison. The first predetermined frequency may correspond to an optimal tissue coagulation temperature. The method may further include measuring a second resonant frequency of the system, making a second comparison between the measured second frequency and a second predetermined frequency, and adjusting the power level based on the second comparison. The second predetermined frequency may correspond a melting point temperature of a clamp arm pad. An ultrasonic instrument and a generator may implement the method.

DEVICES AND METHODS FOR CLOSURE OF TRANSVASCULAR OR TRANSCAMERAL ACCESS PORTS

The present disclosure provides a variety of prostheses, delivery systems and techniques to facilitate closure of transvascular or transcameral access ports. Various embodiments of prostheses are provided including a plurality of radially expandable discs that can be filled with material to facilitate coagulation and to reduce or stop leakage from punctures in vessel walls.

CUTTING MECHANISMS FOR SURGICAL END EFFECTOR ASSEMBLIES, INSTRUMENTS, AND SYSTEMS

A surgical system includes an attaching device having an end effector disposed at the distal end thereof. The end effector includes a support member, a wrist pivot pivotably coupling the end effector to the attaching device, and first and second jaw members pivotably coupled to one another and the support member. A first cable is operably coupled to the wrist pivot and configured to articulate the end effector relative to the attaching device. Second and third cables are operably coupled to the jaw members and configured to pivot the jaw members relative to the support member. A first actuation of the second and third cables collectively pivots the first and second jaw members relative to the support member. A second actuation of the second and third cables pivots the first and second jaw members relative to one another and the support member between a spaced-apart position and an approximated position.

Method and apparatus for post-operative tuning of a spinal implant

A tunable implant, system, and method enables a tunable implant to be adjusted within a patient. The tunable implant includes a securing mechanism to secure the implant in the patient, a actuation portion that enables the implant to move and an adjustment portion that permits adjustment of the implant after the implant has been positioned within the patient. The method of adjusting the tunable implant includes analyzing the operation of the implant, determining if any adjustments are necessary and adjusting the implant to improve implant performance. The implant system includes both the tunable implant and a telemetric system that is operable to telemetrically receive data from the tunable implant where the data is used to determine if adjustment of the tunable implant is necessary. The system also includes an instrument assembly that is used for performing spinal surgery where the instrument assembly includes a mounting platform and a jig.

Integrated operating room lighting and patient warming system—design and components

A patient warming system for stabilizing and/or heating and cooling a patient includes a plurality of solid-surface sections arranged for attachment to a surgical table and a warming pad layer comprising a plurality of warming pads configured for removable connection to the plurality of solid-surface sections. At least one of the plurality of solid-surface sections includes a power connector for connection to an external power source.
