  • Patent number: 11890431
    Abstract: A flexible guide tube having a deflectable distal end is disclosed with at least first and second tensioning lines coupled to a deflectable distal end of the flexible guide tube. The first tensioning line is configured to deflect the distal end of the flexible guide tube in a first direction and the second tensioning line is configured to deflect the distal end of the flexible guide tube in a second direction that is opposite the first direction. A handle is coupled to flexible tube, the handle having a medial portion with a longitudinal axis substantially parallel with at least a portion of the flexible guide tube, a first actuator disposed proximal the medial section, and a second actuator disposed distal the medial section.
    Type: Grant
    Filed: September 28, 2020
    Date of Patent: February 6, 2024

  • Patent number: 9162017
    Abstract: A pump for inducing flow within a vascular system comprises a cannula having a first configuration for deployment within the vascular system and a second configuration for directing the fluid flow within the vascular system, where the second configuration has a greater diameter than the first configuration. An impeller is configured to induce the fluid flow by rotation about an axis. The impeller has a first radius in the first configuration and a second radius in the second configuration, where the second radius is greater than the first radius.

  • Publication number: 20070299439
    Abstract: A bipolar electrosurgical instrument comprises a handle (5), a body (1) joined to the handle, and a jaw assembly (12) joined to the body and arranged such that manipulation of the handle allows the opposed jaws of the jaw assembly to be opened and closed with respect to one another. A first of said opposed jaws (14) has at least a first coagulating electrode, and the other of said opposed jaws (13) has at least a second coagulating electrode and a cutting electrode (16) separated from the second coagulating electrode by an insulating member (17). The instrument is manipulated at the surgical site such that the jaws of the jaw assembly (12) are open with respect to one another, with the cutting electrode (16) and at least one of the first and second coagulating electrodes contacting tissue at the surgical site.

  • Publication number: 20060271042
    Abstract: A bipolar electrosurgical forceps comprises an elongated tubular barrel having a proximal end, a distal end and a lumen extending between these two ends. A handle is provided at the proximal end of the barrel and includes an actuating member for opening and closing a pair of forceps jaws that are mounted at the distal end of the barrel. The forceps jaws include cam slots in a proximal head portion thereof. A coupling member extends between the actuating member on the handle and the pair of forceps jaws. The coupling member includes drive pins that cooperate with the cam slots whereby squeezing of the actuating mechanism first effects pivotal rotation of the pair of forceps jaws over a first range of motion of the actuating member and translation without rotation of the forceps jaws over a second range of motion of the actuating member.
