    Abstract: An injectable composition having dermal filling and tissue expanding activity comprises: (1) a quantity of elastin sufficient to bring about dermal filling and tissue expansion when injected into a subject in need of dermal filling and tissue expansion; and (2) a pharmaceutically acceptable carrier. The composition can further comprise collagen; in other alternatives, the composition can further comprise hyaluronic acid; and one or more of the elastin, the collagen, and the hyaluronic acid, if present can be cross-linked, either intramolecularly or intermolecularly. The elastin, however, is the primary filler, even if collagen or hyaluronic acid are included in the composition.

  • Patent number: 10314645
    Abstract: Surgical end effectors with increased stiffness are described herein. Increased stiffness can be accomplished in a variety of manners, including by increasing a height of each jaw member of an end effector. For example, end effector jaw members can include tapered heights that decrease from a proximal end of the jaw member to a distal end thereof. In one embodiment, first and second jaw members can each have a height measured at a proximal end thereof that is greater than half of an overall height of the end effector, while at a distal end thereof a sum of heights of the first and second jaw members can approximately equal the overall height of the end effector. Overlapping or otherwise fitting such jaw members together can create an end effector with greater stiffness that can be used to apply greater compression force to tissue during operation.

    Abstract: A bipolar electrosurgical instrument has a handle and an operation tool. The operation tool is mounted on a front end of the handle and has multiple holes densely formed in and spread over at least one working surface of the operation tool. With the multiple holes formed on the at least one working surface of the operation tool, tissues of a surgical site can be heated uniformly and adhesion of the surgical site is minimized. Moreover, since the multiple holes are directly formed on the at least one working surface, the multiple holes do not become shallow under long-term use and no toxic gas would be released when the operation tool is heated to high temperature. Accordingly, anti-adhesion effect of the operation tool and health of medical staffs can be assured.

  • Patent number: 9155587
    Abstract: Visual electrode ablation systems are described herein which include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. An electric current may be passed through the fluid such that it passes directly to the tissue region being imaged and the electrical energy is conducted through the fluid without the need for a separate ablation probe or instrument to ablate the tissue being viewed.

  • Patent number: 9149327
    Abstract: A method and device for determining the transmuriality and/or continuity of an isolation line formed by a plurality of point contact ablations. In one embodiment, a method for determining the size of a lesion (width, depth and/or volume) is disclosed, based on contact force of the ablation head with the target tissue, and an energization parameter that quantifies the energy delivered to the target tissue during the duration time of the lesion formation. In another embodiment, the sequential nature (sequence in time and space) of the ablation line formation is tracked and quantified in a quantity herein referred to as the “jump index,” and used in conjunction with the lesion size information to determine the probability of a gap later forming in the isolation line.
