摘要： Catheters of the present disclosure include a catheter shaft and an expandable tip, which can retrieve materials slightly larger than an inner diameter of the catheter shaft. The tip may be expandable such that it can easily transform from a first size and shape to a second size and shape to aid in the retrieval of the materials (i.e., the thrombus, embolus, or foreign body). Catheter tips may be expanded by inflation, removal of a constraining member, or an input such as heat, light, or electrical energy.

摘要： A vaso-occlusive device delivery assembly includes a pusher assembly and a vaso-occlusive device detachably coupled to the pusher assembly by an attachment member is frictionally secured within a lumen of the pusher assembly. A heat generating member is disposed in the pusher assembly lumen, along with a pressure generating material, such that, when heat is generated by the heat generative device, the pressure generating material increases a pressure in the pusher assembly lumen, thereby dislodging the attachment member from the pusher assembly and detaching the vaso-occlusive device from the pusher assembly.

摘要： The invention provides intrafallopian devices and non-surgical methods for their placement to prevent conception. The efficacy of the device is enhanced by forming the structure at least in part from copper or copper alloy. The device is anchored within the fallopian tube by a lumen-traversing region of the resilient structure which has helical outer surface, together with a portion of the resilient structure which is biased to form a bent secondary shape, the secondary shape having a larger cross-section than the fallopian tube. The resilient structure is restrained in a straight configuration and transcervically inserted within the fallopian tube, where it is released. Optionally, permanent sterilization s effected by passing a current through there resilisent structure to the tubal walls.

摘要： The disclosed methods and devices utilize various techniques to detach the distal end of a catheter from an obstruction with minimal invasiveness and effort by the surgeon. As reflux of an embolic agent or hardening material over the catheter tip is a major causative factor in the increased morbidity/mortality of embolization procedures and also a technical limitation preventing a better cure rate, a method has been developed for the detachment of the distal end of catheters within the body, preferably with no regard to the amount of reflux, and preferably at the proximal edge of the reflux, in order to be able to make embolization procedures safer and more effective.

摘要： Apparatus for delivering a medical device to a location in a patient's body includes an elongate catheter body having a proximal end and a distal end, a pod coupled with the distal end of the catheter body and adapted to house the medical device during delivery to the location and to open to release the medical device, and at least one distal actuator coupled with at least one of the pod and the medical device. The distal actuator is adapted to promote opening of the pod. A method involves advancing a pod at the distal end of an elongate catheter to the location within the body and activating an actuator coupled with the pod and/or the medical device to cause the pod to open. Opening the pod releases the medical device.
