  • Patent number: 10687844
    Abstract: An improved catheter atherector for shaving, cutting, and emulsifying accumulated plaque into fine particles, and removing the particles from blood vessel walls without cutting or permanently stretching the walls, and without substantially blocking the blood flow through the vessel during plaque removal operation. The catheter atherector includes an emulsification reduction sphere and extraction wire that rotate and move axially inside the vessel to engage the occlusive material. Emulsified occlusive reduced plaque material and blood only flow in a proximal direction into a catheter lumen. The operation of the device does not substantially disrupt blood pressure within the blood vessel.

    Abstract: A method of aspirating a vascular occlusion from a remote site is provided. The method includes the steps of advancing a first elongate tubular body through a vascular access site and into a body vessel, advancing a second tubular body distally to extend beyond the first elongate tubular body to reach the remote site, and aspirating thrombus from the site into the lumen by applying pulsatile vacuum to the first elongate tubular body. The second tubular body has a lumen and a length that is shorter than the first elongate tubular body. The pulsatile application of vacuum may cause the distal tip of the second tubular body to open and close like a jaw, which facilitates reshaping the thrombus or biting or nibbling the thrombus material into strands or pieces to facilitate proximal withdrawal under negative pressure through the lumen of the second tubular body.

The plastic needle is connected at the distal end of the metal connection body, and the metal connection body is connected to the distal end of an ultrasonic hand piece. The ultrasonic phacoemulsification needle employing a design of splitting the connection body and the needle alleviates the difficulties for manufacturing otherwise caused by the conventional phaco tip designs. It reduces the surgical costs from patients. In addition, the ultrasonic phacoemulsification needle using a plastic body reduces the likeliness of punctuating the capsule bag, which otherwise easily occurs in the metal needle case due to the extremely sharp rigid tip at the end of the needle, thus the risks of surgery are reduced and safety is improved.

  • Patent number: 10561487
    Abstract: There is described a method, a system, and a device for the anchoring of and into a corpus disposed distally in a conduit by engaging a stranded tube with the corpus and unwinding the wound threads of the stranded tube into unwound threads. Engagement includes the use of handling and manipulation shaft to dispose the stranded tube proximally, distally, or in the interior to the corpus. Unwinding, of the stranded tube is achieved by rotating a tube tool against the stranded tube. Unwinding liberates the helically coiled unwound strands in “corkscrew” rotation into the corpus. Proximal retrieval of a corpus is achieved by proximal retrieval of the stranded tube anchoring the corpus. An unwound stranded tube is operable as a fastener, as an electrical lead, and as a support for a device.

  • Patent number: 10548655
    Abstract: Aspects of the present disclosure include an attachable power and control system to supply energy to electrodes of a wiping electrode coagulation system of a surgical device. A surgical device includes electrodes at an end of effector to aide in sealing during various surgical procedures. During the procedure, the surgeon may wipe the surgical site with the end effector, causing the electrodes to touch the fractured area. Electrosurgical energy may be applied to the electrodes during the wiping, causing coagulation of smaller vessels. The attachable power and control system may be configured to slide over the shaft of the surgical device. The power and control system also may be configured to supply power to the electrodes and to control when energy is applied to the electrodes, based in part, for example, on measuring a distance or angle of the opening of the jaws at the end effector.

  • Patent number: 10524769
    Abstract: A vein harvesting assembly for harvesting a vein in a body comprises: a dissecting member, with the dissecting member being insertable into the body and moved along a vein to dissect tissue surrounding the vein. A covering member possesses a proximal end portion and a distal end portion, with the covering member possessing a covered space extending from the proximal end portion to the distal end portion, and the covering member being mountable on and movable along the dissecting member when the dissecting member is positioned in a living body. A cutting member is comprised of an elongated member and a blade member so that rotation of the elongated member results in turning of the cutting member to cut tissue surrounding the vein. The cutting member is insertable into the space in the covering member and is movable in a distal direction along the space.

  • Patent number: 10500319
    Abstract: A surgical hand piece has a source of ultrasonic energy provided to a connecting body having a first passage with one end to receive fluid from a first source and the other end at the connecting body distal end. A work tip has first and second tubes each having at least one opening at its distal end and the proximal end of one or both of the tubes connected to the connecting body distal end to receive the ultrasonic energy and to selectively receive or discharge fluid from either the first or second source as controlled by a valve. A cannula is provided which is adapted to be placed in an opening in the cornea through which the work tip extends during the removal of cataracts from the eye by phacoemulsification. The cannula may be equipped with channels that permit additional infusion of fluid into the eye during the procedure, which infusion also cools the surrounding corneal tissue to protect against heat generated by the ultrasonic vibration of the work tip.
