    Patent number: 9060749
    Abstract: In some aspects, a surgical procedure for the removal of a prostate gland is provided. The procedure comprises: (a) positioning an implant material within the urethra, (b) removing the prostate, thereby creating a urethral stump and a bladder neck, wherein the implant material occupies the urethral stump, the bladder neck, or both, and (c) securing the bladder neck to the urethral stump in an anastomosis procedure to establish a path of urine flow from the bladder to an external urethral opening (e.g., the meatus). Subsequently, the implant material is removed from the urethra, for example, by natural urine voiding or by flowing a removal fluid through and/or around the implant material in the urethra. In other aspects, a medical kit is provided.

  • COMPUTED TOMOGRAPHY DEVICE BASED ON STRAIGHT TRAJECTORY AND X-RAY IMAGING DEVICE
    Publication number: 20150085973
    Abstract: A straight trajectory CT device can be used in radiation imaging. The device includes: a ray-generating unit that generates a ray within a specific range of field angle; a channel for an object to be inspected though which the object to be inspected passes; a first collimator; and a ray receiving unit provided on both sides of the channel for the object to be inspected. The ray beam is received by the ray receiving unit after penetrating the first collimator and the object to be inspected in order. The ray generating unit is static and the first collimator moves in the same direction as the ray receiving unit. This direction is parallel to the channel for the object to be inspected. The device can complete computed tomography with a minimum of one ray receiving unit, thereby simplifying the structure of the device and reducing its cost.
