The laser system may further include a laser energy delivery system having a first end which receives laser energy from the laser and a second end which delivers the laser energy to the environment. The laser system may further include a switch unit located remote from the base unit and including a switch controller, a second antenna operatively coupled to the switch controller, and a user operable switch. The switch unit may be connected to the base unit through a tether. The controller may determine when the laser energy is provided to the laser energy delivery system based on a signal from the switch unit, the signal being sent wirelessly to the controller from the second antenna of the switch unit to the first antenna of the base unit.Type: ApplicationFiled: June 15, 2018Publication date: October 11, 2018Inventor: Kenneth Chalfant

Publication number: 20180289421Abstract: Methods for treating dermal infection in an appendage of a mammal can include removing, such as by grinding off, a first nail portion of an appendage a mammal to expose a second nail portion of the appendage. A laser absorbing compound can be applied to the second nail portion of the appendage. The second nail portion can be irradiated with a laser of a treatment system to selectively heat the laser absorbing compound. Methods can also include applying a system for treating dermal fungal infection. A system can include a laser, an imaging unit for obtaining infection image data, and/or an alignment stage for receiving an infected portion of a mammal including the dermal fungal infection and aligning the infected portion of the mammal with the laser. A system can also include a control unit for controlling relative movement between the laser and the alignment stage.Type: ApplicationFiled: April 5, 2017Publication date: October 11, 2018Inventor: Iouri Poutivski

Publication number: 20180289422Abstract: A method and system for determining a measure of a risk of a patient developing cardiac conduction abnormalities as a result of transcatheter cardiac treatment. The method includes providing a patient-specific anatomical model representing cardiac region and an implant model representing a finite element representation of a cardiac implant. The method includes virtually placing said implant model into said patient-specific anatomical model. A measure of mechanical interaction between the implant model and the patient-specific anatomical model is determined and a measure of risk of the patient developing cardiac conduction abnormalities is determined on the basis of the determined mechanical interaction.Type: ApplicationFiled: April 29, 2016Publication date: October 11, 2018Inventors: Peter Eddy J Mortier, Gianluca De Santis, Matthieu Robert Anna Firmin De Beule

Publication number: 20180289423Abstract: Described herein are systems and methods in which a surgeon can use computer-implemented deformity assessment and correction tools to create 3D models of a bone. To ensure adequate healing, a surgeon may choose to use a prefabricated bone plate, a semi-customized bone plate, or a fully-customized bone plate to hold first and second bone portions in a corrected position. To select the appropriate prefabricated bone plate, the surgeon may identify three landmark locations on the first and second bone portions corresponding to desired fixation hole locations on the bone plate. The surgeon can then use a software application to evaluate multiple bone plate designs in a library and compare the average proximity of the landmark locations to fixation hole locations on each of the bone plate designs. Then, the surgeon can determine which bone plate design best fits the patient anatomy based on his comparison.Type: ApplicationFiled: March 2, 2018Publication date: October 11, 2018Inventors: Manoj Kumar Singh, Anup Kumar

Publication number: 20180289425Abstract: Systems and methods for determining position and orientation of a bone of an anatomical feature are described. These include the use of a wearable holder configured to be mounted about an outer-skin surface of the anatomical feature, such that the anatomical feature and the bone are positioned in fixed relation with respect to the wearable holder when the wearable holder is mounted about the anatomical feature. Reference marker arrays are fixedly mounted to the wearable holder, each being positioned on the wearable holder to identify a landmark of the bone within the wearable holder when the wearable holder is mounted to the anatomical feature. The position and orientation of the reference markers are trackable to determine position and orientation of the wearable holder in a reference coordinate system, thereby enabling position and orientation of the landmarks on the bone to be determined.Type: ApplicationFiled: April 6, 2018Publication date: October 11, 2018Inventors: Di LI, Louis-Philippe AMIOT, Pierre COUTURE

Publication number: 20180289427Abstract: A system and method of registering a surgical table and a computer-assisted device includes an articulated arm and a control unit coupled to the articulated arm. The articulated arm has a distally mounted instrument configured to be inserted into a patient at a body opening. The control unit is configured to detect a first motion of a surgical table coupled to the control unit via a communications connection. The first motion of the surgical table causes a corresponding second motion of a control point of the articulated arm. The control unit is further configured to determine a first angular direction of the first motion in a surgical table coordinate frame, determine a second angular direction of the second motion in a computer-assisted medical device coordinate frame, and determine a third angular relationship between the surgical table and the computer-assisted medical device based on the first and second angular directions.Type: ApplicationFiled: October 27, 2015Publication date: October 11, 2018Inventors: Paul G.
