摘要： Implantable devices formed of materials which are not readily imageable, and which may shift from a delivery configuration to a deployment configuration upon deployment, are delivered and deployed with a deployment/delivery device having sensors generating a signal indicating contact of the delivery/deployment device with tissue to guarantee purchase of the implantable device with tissue upon deployment. The implantable device may be a tissue anchor with talons which shift from a delivery configuration to a deployed configuration. The sensors may be positioned along a distal end of the delivery/deployment device to indicate purchase of the device with tissue, to ensure purchase of the talons with tissue upon deployment. The sensors may include at least three sensors, which may be spaced apart from one another, to indicate full contact of the distal end of the delivery/deployment device with tissue. The sensors may optionally be aligned with the talons.

摘要： Devices, systems, and methods for delivery and deployment of an implantable device. The implantable device may be an anchor. The device includes an anchor garage configured to deliver the anchor, therein, to a target site, and an atraumatic shield movable with respect to the anchor garage. A biasing element biases the atraumatic shield into position with respect to the anchor garage. In some embodiments, the distal end of the anchor garage is a sharp tissue-penetrating end, and the atraumatic shield is biased distally over such sharp end. A limit stop may be provided to limit the extent to which the anchor garage extends distally, thereby limiting tissue penetration by the anchor garage and the depth of deployment of the anchor. An indicator may be positioned and/or configured to provide an indication of the relative positions of the anchor garage and the atraumatic shield.

摘要： A delivery/deployment system for delivering an implantable device within an implantable device housing and for deploying the implantable device from the implantable device housing. A stylet may be used to longitudinally advance or retract the implantable device with respect to the implantable device housing, such as to extend and deploy the implantable device from the implantable device housing. The delivery/deployment system has an implantable-device-extension-limiter arrangement configured to limit the distance which the implantable device may be extended from the implantable device housing. The delivery/deployment system optionally also has an implantable-device-rotation-limiter arrangement configured to limit rotation of the implantable device with respect to the implantable device housing.

摘要： An introducer assembly is adapted for deploying a medical device. The introducer assembly includes an introducer body that is adapted to accommodate a volume of blood therein. An antechamber is coupled with the introducer body. A first hemostasis valve is disposed proximal of the antechamber and fluidly couples the introducer body with the antechamber. A second hemostasis valve is disposed distal of the antechamber and is adapted to allow the medical device to pass therethrough.

摘要： Implantable devices formed of materials which are not readily imageable are delivered and deployed with a deployment/delivery device having one or more sensors generating a signal indicating a condition of the implantable device relative to the deployment site. For instance, the signal indicates at least one or more of the following: purchase of the implantable device with tissue, level of purchase of the implantable device with tissue, the position of the implantable device relative to the deployment site, seating of tissue with respect to the implantable device, extent of contact of the implantable device with tissue, or further information about the implantable device and/or the delivery/deployment device. As such, the implantable device need not be imaged to determine the relationship of the implantable device relative to the deployment site.
