  • Medical implant delivery system and method of use
    Patent number: 10751208
    Abstract: An implant delivery system includes a delivery catheter and a delivery mechanism slidably disposed in a lumen of the delivery catheter. The delivery mechanism includes an annular channel and a compressible annular bushing disposed within the annular channel. The annular bushing is configured for being placed between a compressive profile and an expanded profile. The implant delivery system further includes an implant coaxially disposed between the delivery catheter and the delivery mechanism. The delivery catheter lumen is sized to maintain an engagement element of the implant within the annular channel and to urge the annular bushing into the compressive profile. The implant constrains a distal tip of the delivery mechanism to assume a straight geometry. The distal tip is configured for assuming a curved geometry when the implant is deployed from the delivery catheter.
    Type: Grant
    Filed: October 4, 2018
    Date of Patent: August 25, 2020
