Patent application number | Description | Published |
20120123402 | Method and Apparatus for Vascular Tissue Sealing with Reduced Energy Consumption - An end effector assembly for use with an electrosurgical instrument is provided. The end effector assembly includes a pair of opposing jaw members configured to grasp tissue therebetween. Each of the opposing jaw members includes a non conducting tissue contact surface and an energy delivering element configured to perforate the tissue to create an opening, extract elastin and collagen from the tissue and denaturize the elastin and the collagen in the vicinity of the opening. | 05-17-2012 |
20120123413 | Method and Apparatus for Vascular Tissue Sealing with Active Cooling of Jaws at the End of the Sealing Cycle - An end effector assembly for use with an electrosurgical instrument is provided. The end effector assembly has a first jaw member and a second jaw member. The second jaw member includes a channel defined therein and coupled to a cooling agent source and at least one venting port defined therein and fluidly coupled to the channel. During active cooling of the second jaw member, the cooling agent source is configured to supply a cooling agent to the channel. | 05-17-2012 |
20120296239 | Destruction of Vessel Walls for Energy-Based Vessel Sealing Enhancement - An end effector assembly for use with an electrosurgical instrument is provided. The end effector assembly includes a pair of opposing jaw members configured to grasp tissue therebetween, at least one jaw member adapted to connect to a source of electrosurgical energy to seal tissue disposed between jaw members during a sealing process. At least one of the jaw members includes an activator configured to selectively impart mechanical perturbations to the at least one jaw member during the sealing process. | 11-22-2012 |
20120296317 | Optical Energy-Based Methods and Apparatus for Tissue Sealing - Optical energy-based methods and apparatus for sealing vascular tissue involves deforming vascular tissue to bring different layers of the vascular tissue into contact each other and illuminating the vascular tissue with a light beam having at least one portion of its spectrum overlapping with the absorption spectrum of the vascular tissue. The apparatus may include two deforming members configured to deform the vascular tissue placed between the deforming members. The apparatus may also include an optical system that has a light source configured to generate light, a light distribution element configured to distribute the light across the vascular tissue, and a light guide configured to guide the light from the light source to the light distribution element. The apparatus may further include a cutting member configured to cut the vascular tissue and to illuminate the vascular tissue with light to seal at least one cut surface of the vascular tissue. | 11-22-2012 |
