Abstract: Anchor delivery systems include anchors having a generally cylindrical body with a rail on top for positioning within a delivery device slot. The rail incorporates a side-bulge as a retaining feature which axially extends along a majority of the length of the rail. The bulge interferes with a corresponding hourglass cutout in the delivery device slot to prevent the anchor from stripping out of the delivery device when the delivery device is retracted through tissue. The anchors are symmetrical along a length and width to facilitate loading within the delivery device. The distal portion of the delivery device includes a series of distally-extending barbs that intentionally change the penetration force required to push the device tip through tissue.

Abstract: Systems for fusing arthroscopic video data are described. A system comprises an arthroscopic assembly, an inertial measurement unit (IMU) mounted on the arthroscopic assembly, a processor, and a processor-readable storage medium. An arthroscopic surgical plan, images from the arthroscopic assembly, and measurements from the IMU may be obtained. The images and the measurements may be combined to form a data combination.

Abstract: The invention relates to a method of determining the sagittal rotation of a patient's pelvis based on a standard anterior posterior X-ray-image with known image parameters and a calibration of the image, for example by using at least one King-Mark calibration object. The angle of the pelvic rotation is determined between a pelvic plane which is orthogonal to the midsagittal plane of the pelvis, and the image plane of the X-ray-image. Assuming the patient's position shown on the X-ray-image represents a standard neutral position, the X-ray-image plane can be used as a functional reference plane for further calculations, for example during hip-replacement surgery. The present invention further relates to a corresponding computer program and system.

Abstract: A suture passing device has a curved, slotted shaft with a piercing end and an integral suture grasper, allowing the surgeon to pierce through a first tissue portion with the device and extend a looped portion of monofilament loaded within the shaft into the repair site. The shaft is then rotated so that the monofilament is allowed to fall out of the shaft through the slot. The surgeon then pierces a second tissue portion with the device and extends the suture grasper to capture the looped portion of monofilament. The monofilament is retrieved through the second tissue portion and a suture is passed through the looped portion of the monofilament. Finally, the flexible member is used to pull the suture through the tissue and the suture can be tensioned to close the hip capsule.
