Device detachment systems with indicators
First Claim
1. A medical device detachment system for placement of a medical implant in a patient'"'"'s vasculature, the system comprising:
- a housing configured to receive a proximal end of an elongate delivery member and a proximal end of an elongate core member slidably disposed within the delivery member;
a grasping mechanism disposed within the housing and configured to grasp a portion of the core member in response to receiving an input signal;
a user input mechanism configured to receive the input signal and permit movement of the grasping mechanism to grasp the proximal end of the core member;
a first sensor configured to provide an output signal confirming placement of the proximal end of the core member at a determined position within the housing;
a second sensor configured to provide an output signal indicative of a proximity of the grasping mechanism relative to the delivery member; and
an indicator connected to the first and second sensors and configured to receive one or more output signals from the first and second sensors and to provide corresponding indication signals to a user when one or more output signals are received from the first or second sensors.

Abstract
A medical device detachment system receives an elongate delivery member, having a lumen, and an elongate core member. The system includes a housing, a user input mechanism for receiving a user input to effect detachment of a medical device, such as an embolic coil, from a distal end of the delivery member, and a grasping mechanism for grasping and moving a proximal end of the core member relative to a proximal end of the delivery member. The system also includes a first sensor detecting positioning of the proximal end of the core member within the housing, and a second sensor, detecting movement of the grasping mechanism. An indicator is connected to the first and second proximity sensors and provides feedback to a user.
