  • Renal monitor
    Patent number: 8715254
    Abstract: A continuous Glomerular Filtration Rate (GFR) estimation system may include a Foley catheter, a continuous urine creatinine sensor, and a urine output monitor. The continuous GFR estimation system computes creatinine clearance as CrCl=(Ucr×Uvol)/Pcr×Tmin), where Ucr is urine creatinine in mg/dL, Uvol is urine volume in mL, Pcr is plasma (serum) creatinine in mg/dL, and Tmin is time in minutes. A Foley catheter may be used to withdraw urine from the bladder. The urine may be delivered to a urine output monitor that provides the Uvol value over a time Tmin. Attached to the catheter is the flow-through continuous urine creatinine sensor for providing the Ucr value. The remaining parameter is Pcr. Because serum creatinine levels do not change rapidly over time, a blood sample may be withdrawn prior to the start of the continuous GFR to obtain the Pcr value.

  • Catheter Delivery System to Release a Self-Expanding Implant
    Publication number: 20140121753
    Abstract: A percutaneous trans-luminal catheter delivery system for an implant. The system includes a catheter shaft with a distal end to carry the implant and an elongate housing at a proximal end that an operator can grasp when deploying the implant. The shaft has an inner push component which can push on the implant in a distal direction and an outer sheath component which radially surrounds the implant until deployment of the implant into the bodily lumen. The outer sheath component is capable of being pulled proximally, from the housing, to deploy the implant, the housing being mounted on a proximal end portion of the push component and defining a channel. The housing may contain a sheath slitter that is fixedly mounted relative to the length of the channel that can slit the outer sheath as the outer sheath is caused to move proximally in the channel relative to the slitter.
