Abstract
The present invention provides for implant device delivery apparatuses and related methods of use. The delivery systems of the present invention incorporate a stretch resistant tube that advantageously makes the implant device, such as an embolic coil, stretch resistant while a delivery system is being used to position the implant device at a desired target site.
Claims34
An implant delivery system comprising:
- a. a delivery pusher;
- b. an implant connected to said delivery pusher;
- c. a tether connecting said implant to said delivery pusher;
- d. a heater;
- e. wherein said tether is in a pre-tensioned state such that said implant device is released from said delivery pusher less than 1 second after activation of said heater.
2 more elements
A method of releasing an implant from a delivery device comprising:
- a. providing a delivery device having an implant connected to said delivery device with a tether;
- b. positioning said implant at a target location within a lumen of a patient;
- c. activating a heater of said delivery device such that said implant is released from said delivery device in less than about 1 second after activation of said heater.
An implant delivery system comprising:
- a. a delivery pusher having an outer surface;
- b. an implant connected to said delivery pusher;
- c. a tether connecting said implant to said delivery pusher;
- d. a heater;
- wherein said tether is in a pre-tensioned state such that said implant device is released from said delivery pusher after activation of said heater and prior to a temperature of said outer surface of said delivery pusher exceeding about 50° C.
2 more elements
An implant delivery system comprising:
- a. a delivery pusher;
- b. an implant connected to said delivery pusher;
- c. a tether connecting said implant to said delivery pusher;
- d. a heater;
- wherein said tether is pre-tensioned so that release of said implant from said delivery pusher occurs by releasing potential energy thereby applying a force on said implant.
