Stents generally can include a tubular structure having circumferentially positioned undulating wires that extend over a majority of a length of the stent such that the undulations oscillate circumferentially to define a circumference of the stent. The undulations can wrap over and under adjacent undulations to form an interwoven structure. Additionally, or alternatively, adjacent wires can be joined. Wires forming the stent can be cut from elastic tubing such that each wire has a three-dimensional shape.

DEVICE, KIT AND METHOD FOR CORRECTION OF SPINAL DEFORMITY
A device, kit and method for the correction of spinal deformity using an anterior approach. The device comprises a screw-head platform, wherein the screw-head platform comprises a primary recess for receiving a primary rod, and a main vertebral body screw rotatably connected to the screw-head platform .
A detachment system configured to deliver an implantable medical device to a target location of a body vessel includes a generally hollow distal tube and an engagement system. The distal tube can have an inner lumen having a first diameter therethrough and a narrowed portion positioned on at least a portion of the distal tube and having a second diameter lesser than the first diameter. The engagement system can be slidably disposed within the inner lumen and have a detachment feature connected to the implantable medical device and a locking member engaging the detachment feature and interfacing with the narrowed portion of the distal tube. The locking member is configured to deploy the implantable medical device when the locking member is displaced from the narrowed portion of the distal tube.

TECHNOLOGIES FOR DETERMINING SEATING OF AN ORTHOPAEDIC IMPLANT DURING AN ORTHOPAEDIC SURGICAL PROCEDURE
Technologies for determining seating of an orthopaedic implant during an orthopaedic surgical procedure includes an impaction sensor and an impaction analyzer. The impaction sensor produces sensor data, in response to an impaction between an orthopaedic mallet and a surgical tool indicative of an initial impact and a secondary impact of the impaction. The impaction analyzer analyzes the sensor data to determine a temporal length between the initial and secondary impacts and determines whether the orthopaedic implant is sufficiently seated into the bone based on the temporal length,
The disclosure relates to an endoscopic light source that includes a first emitter. The first emitter may emit light of a first wavelength at a dichroic mirror which reflects the light of the first wavelength to a plurality of optical fibers. The endoscopic light source further comprises a second emitter. The second emitter may emit light of a second wavelength at a second dichroic mirror which reflects the light of the second wavelength to the plurality of optical fibers. In one embodiment, the first dichroic mirror may be transparent to the light of the second wavelength, allowing the light of the second wavelength to pass through the first dichroic mirror.
