  • Publication number: 20130041390
    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.

  • Patent number: 8318195
    Abstract: The resorption of a medical implant can be controlled with the use of particles embedded in a resorbable bulk material forming the implant or portion thereof. The implant can be removed from a body of a mammal by natural biological mechanisms after use. The resorption of the implant can involve swelling and/or hydrolyzing of the particles within the implant upon contact with a body fluid such that porosity and flow of fluid within the bulk material of the implant is increased. Resorption of the implant may also involve the use of particles with magnetic properties embedded within the implant such that an applied magnetic field causes the particles to vibrate within the bulk material thereby increasing the porosity and thus the flow of fluid, hence facilitating resorption of the implant. The resorption rate of the implant can be controlled by modulating swelling, hydrolysis, or movement of the embedded particles.
