A third orientation indicator is formed on the body, and the third orientation indicator disposed relative to the second orientation indicator such that when the distal tip is viewed in a second side view, the third orientation indicator and the second orientation indicator overlap and visually contrast with the body. The second side view and the first side view are substantially 90 degrees apart about the longitudinal axis. | 2018-09-27 |
20180271599 | LASER ENERGY DELIVERY DEVICES INCLUDING DISTAL TIP ORIENTATION INDICATORS - A laser ablation catheter includes a distal tip, and the distal tip includes a body that defines a longitudinal axis. A first orientation indicator is formed on the body, and the first orientation indicator has an alphanumeric shape. A second orientation indicator is formed on the body. The second orientation indicator is disposed relative to the first orientation indicator such that when the distal tip is viewed in a first side view, the second orientation indicator and the first orientation indicator overlap, appear as the alphanumeric shape, and visually contrast with the body. The second orientation indicator is configured such that when the distal tip is viewed in a second side view, the second orientation indicator appears as the alphanumeric shape and visually contrasts with the body, the second side view and the first side view being substantially 90 degrees apart about the longitudinal axis. | 2018-09-27 |
20180271600 | TISSUE AND STONE REMOVAL DEVICE AND RELATED METHODS OF USE - Embodiments of a medical device and related methods of use are provided for extracting tissue. The device may include an elongate member having a proximal end and a distal end. Two or more channels may extend through the elongate member from the proximal end to the distal end, and a morcellating device may be included in one of the channels. In addition, one of the channels may be configured as a return channel for extracting the morcellated tissue. | 2018-09-27 |
20180271601 | METHOD FOR IMPLANTING A HIP PROSTHESIS AND RELATED SYSTEM - A method of implanting a hip joint prosthesis into a patient can include obtaining image data of hip joint anatomy of the patient. Physical activities that the patient desires to participate in subsequent to implanting the hip prosthesis can be determined. A size and an initial placement of the hip joint prosthesis based on the image data can be determined. A desired range of motion of the hip joint prosthesis based on the determined physical activities can be determined. A plan can be created comprising a desired implanted location of the hip joint prosthesis and based on the desired range of motion. The plan can be incorporated onto a guide. The plan can be executed with the guide thereby implanting the hip joint prosthesis into the patient at the desired implanted position. | 2018-09-27 |
20180271602 | PATIENT-MATCHED APPARATUS AND METHODS FOR PERFORMING SURGICAL PROCEDURES - A system and method for developing customized apparatus, such as guides, for use in one or more surgical procedures is disclosed. The system and method incorporates a patient's unique anatomical features or morphology, which may be derived from capturing MRI data or CT data, to fabricate at least one custom apparatus or guide. According to a preferred embodiment, the customized apparatus comprises at least one patient-specific surface and or contour, which may be derived from MRI or CT data. Apparatus may be matched in duplicate and oriented around the patient's own anatomy, and may further provide any desired axial alignments or surgical instrument insertional trajectories.
