  • Patent number: 9566124
    Abstract: A medical robotic system has a robotic arm holding a medical device, and a control system for controlling movement of the arm according to operator manipulation of an input device. If the medical device is being commanded to a state exceeding a limitation by a threshold amount, then the control system disengages control of the medical device by the input device, servos the arm so that it remains in its current state, servos the input device so that it is set at a position such that a force being applied on the input device remains at its current level, requests the operator to lighten hold of the input device, sets a parameter associated with the input device upon detecting such lightened hold so that the medical device is commanded to a different state that does not exceed the limitation, and reengages control of the medical device by the input device.

  • Patent number: 9561074
    Abstract: A catheter is adapted to ablate tissue and provide lesion qualitative information on a real time basis, having an ablation tip section with a generally omni-directional light diffusion chamber with one openings to allow light energy in the chamber to radiate the tissue and return to the chamber. The chamber is irrigated at a positive pressure differential to continuously flush the opening with fluid. The light energy returning to the chamber from the tissue conveys a tissue parameter, including without limitation, lesion formation, depth of penetration of lesion, cross-sectional area of lesion, formation of char during ablation, recognition of char during ablation, recognition of char from non-charred tissue, formation of coagulum around the ablation site, differentiation of coagulated from non-coagulated blood, differentiation of ablated from healthy tissue, tissue proximity, and recognition of steam formation in the tissue for prevention of steam pop.

  • Patent number: 9486220
    Abstract: A surgical instrument includes an end effector assembly having first and second jaw members moveable relative to one another between a spaced-apart position and an approximated position for grasping tissue therebetween. In the approximated position, the jaw members cooperate to define a cavity that is configured to house tissue grasped between the jaw members. An injectable material configured for injection into the cavity defined by the jaw members is also provided. The injectable material is configured to substantially surround tissue housed within the cavity. The injectable material is transitionable from a first state, facilitating injection of the injectable material into the cavity, to a second state, wherein the injectable material forms about tissue housed within the cavity to occlude tissue.

  • Patent number: 9445871
    Abstract: An apparatus has a pump module providing pump energy, a resonator and a controller. The resonator includes a gain medium receiving the pump energy from the pump module and producing light; reflective surfaces reflecting light produced by the gain medium back toward the gain medium; and a variable light attenuator receiving light produced by the gain medium. The controller controls the amount of light attenuated by the variable light attenuator such that the apparatus emits windows of pulses of laser light at spaced time intervals, each window containing a plurality of pulses of laser light and each interval between windows being larger than an interval between pulses within a window. The emitted windows of pulses of laser light heat tissue to a temperature that causes coagulation without vaporization.

  • Patent number: 9440046
    Abstract: The method of treating varicose veins and other vascular diseases provides sclerosant fluid through a catheter into the body vessel to be treated. The catheter has a lumen and a plurality of sidewall exits. The sclerosant fluid is provided under sufficient pressure so that it comes out of each exit as a jet of fluid with sufficient velocity to impinge on the vessel wall substantially orthogonal to the wall and thus minimize dilution of the sclerosant fluid and optimize coverage. A movable sheath on the catheter permits selecting a portion of the exits to be uncovered and thus create an infusion zone for the jets of sclerosant fluid which approximately match a desired treatment zone.

  • Patent number: 9427602
    Abstract: A system and method are disclosed for stimulating activation of heat shock proteins and facilitating protein repair in cells and tissues in order to take advantage of the remediative and restorative nature of the increased heat shock protein activation or production and the facilitation of protein repair, while not damaging the cells and tissues. This is accomplished by treating a specified target area with an ultrasound or electromagnetic radiation source which is pulsed and applied or focused to one or more small areas in order to achieve the necessary temperature rise or sufficiently stress the cells and tissue to stimulate heat shock protein production or activation and facilitate protein repair, while allowing the temperature to decay sufficiently quickly so as not to damage or destroy the treated tissue.
