Object capture device

A medical device for collecting objects from a body vessel, including:

• a catheter provided with a proximal end, a distal end and a lumen therethrough;
• an elongate basket provided with a first end and a second end;
• and
• an actuator connected to the first end of the basket and extending through the lumen of the catheter to the proximal end of the catheter;
• wherein the catheter and the basket are movable relative to one another between a first configuration in which the first end of the basket is located within the distal end of the catheter and the second end of the basket extends radially out of the catheter and is everted over the first end of the basket, the second end being constrained in position, and a second configuration in which the first end is withdrawn into the catheter and the everted second end is at least partially inverted, the second end being free from constraint;
• and
• wherein, the medical device is operable so as to release the second end from constraint, and move the catheter and the basket from said first configuration to said second configuration, said movement in use causing objects in a body vessel to be drawn into the basket.

A method of collecting objects from a body vessel, including:

• providing a medical device including a catheter provided with proximal end, a distal end and a lumen therethrough, and an elongate basket provided with a closed first end and an open second end;
• and an actuator connected to the closed first end of the basket and extending through the lumen of the catheter to the proximal end of the catheter;
• wherein the catheter and the basket are moveable relative to one another between a first configuration and a second configuration, wherein in the first configuration the first end of the basket is located within the distal end of the catheter and the second end of the basket extends radially out of the catheter and is everted over the first end of the basket, and in the second configuration the first end and at least part of the second end of the basket is withdrawn into the catheter and the everted second end is at least partially inverted;
• inserting the medical device into a body vessel;
• and
• operating the medical device so as to move the catheter and the basket from said first configuration to said second configuration thereby causing objects in a body vessel to be drawn into the basket.
