    Abstract: A drive assembly for use with a delivery catheter for delivering an implantable medical device includes a drive motor configured to be operably coupled to an inner shaft of the delivery catheter such that operation of the drive motor causes the inner shaft to translate relative to the outer shaft and a controller. The controller is configured to receive a position signal from a position sensor indicating a position of the implantable medical device relative to the outer shaft as well as a motor signal indicating a rotational position of an output shaft of the drive motor. The controller is configured to output a control signal instructing operation of the drive motor based upon the indicated rotational position of the output shaft of the drive motor and the indicated position of the implantable medical device relative to the outer shaft.

  • Publication number: 20190223910
    Abstract: A lead-implantation tool for implanting a lead into a patient includes an elongated body having a distal portion with a tip configured to separate patient tissue to form, or extend through, a tunnel in the tissue when the body is advanced along the tissue. A lead-retention element is formed along the distal portion of the body and includes a cutout defined along the body with a cutout surface wall inset from the body's outer surface. A protrusion extends outwardly from the cutout surface wall with at least a portion of the protrusion extending towards the tip. The protrusion is entirely inset from, or flush with, the body's outer surface. The protrusion is configured to removably receive and retain a portion of the lead while the distal portion of the body is advanced along the tissue and to separate from the lead as the body is withdrawn from the tissue.

    Abstract: A cannula and instrument guide assembly includes a cannula with a proximal portion and a tube. An instrument guide is removably inserted into the proximal portion of the cannula and extends through the cannula to a distal end of the tube. The proximal portion of the cannula has an insufflation port. The instrument guide provides at least one interior passageway to support a shaft of a surgical instrument that passes through the instrument guide. One or more channels on an outer surface of the instrument guide provide a passage for insufflation gas received from the insufflation port to the distal end of the tube. The one or more channels have a first cross-sectional area at a proximal end and a second, larger cross-sectional area at a distal end. The one or more channels may have the first cross-sectional area along a majority of the length of the channels.

    Abstract: The present invention relates to reduction and fixation of bone fractures distal radius and wrist. The invention enables to mobilise the distal fragment in 3 planes and also to correct rotational deformity. The object of the present invention is to realize an external fixator which enables to reduce a fracture and at the desired position and fix the fracture. In case of unsuccessful reduction attempt for the second trial there is no need to dismount the fixator. Another object of the present invention is to realize an external fixator which enables to reduce a fracture in 3 dimensions and to correct the rotational deformity in a preferred degree. Another object of the present invention is to realize an external fixator which can practically be mounted to malunion zone and can be used for reducing in corrective osteotomy operations.
