Medical-device position adjusting method and medical device system
A medical device system includes a medical device that is configured to be delivered to a lesion area in a body lumen, a guide wire that is configured to guide the medical device, a port member that is configured to introduce the guide wire and the medical device into a living body, a proximal-end fixing member that is configured to fix the guide wire and the port member and is provided with an operation unit that is configured to cause the guide wire to move in an insertion/pulling-out direction from the fixed state, an anchor device provided with an anchor portion in a distal portion thereof, and an anchor-device guide wire that is configured to guide the anchor device.
1. A medical device system comprising:
a medical device that is configured to be delivered to a lesion area in a body lumen;
a guide wire that is configured to guide the medical device;
a port member that is configured to introduce the guide wire and the medical device into a living body;
a proximal-end fixing member that is configured to fix the guide wire and the port member and is provided with an operation unit that is configured to cause the guide wire to move in an insertion/pulling-out direction from the fixed state;
an anchor device provided with an anchor portion in a distal portion thereof; and
an anchor-device guide wire that is configured to guide the anchor device.
2. The medical device system according to claim 1 ,
wherein the proximal-end fixing member is provided with a port-member fixing portion to which the port member is fixed, a guide-wire fixing portion to which the guide wire is fixed, and a medical-device guiding portion that is configured to guide the medical device out in a direction different from the insertion/pulling-out direction of the guide wire.
3. The medical device system according to claim 2 ,
wherein the guide-wire fixing portion is provided with a holding portion that is configured to hold and fix the guide wire, and the operation unit that causes the holding portion to move in the insertion/pulling-out direction with respect to the port member.
4. The medical device system according to claim 1 , wherein the anchor portion comprises a balloon that is configured to be dilated to fix the position of a portion of the guide wire relative to the body lumen.
5. The medical-device system according to claim 1 , wherein the medical device comprises a bladed balloon.
6. A medical device system comprising:
a medical device that is configured to be delivered to an area in a body lumen;
a guide wire that is configured to guide the medical device in the body lumen to the area;
an anchor device provided with an anchor portion in a distal portion thereof;
an anchor-device guide wire that is configured to guide the anchor device in the body lumen;
a port member that is configured to introduce the guide wire and the medical device into the body lumen; and
a proximal-end fixing member that is configured to fix the guide wire and the port member and is provided with an operation unit that is configured to cause the guide wire to move in an insertion/pulling-out direction from the fixed state,
the anchor device being configured to fix an axial position of a distal portion of the guide wire relative to the body lumen.
7. The medical device system according to claim 6 ,
wherein the proximal-end fixing member is provided with a port-member fixing portion to which the port member is fixed, a guide-wire fixing portion to which the guide wire is fixed, and a medical-device guiding portion that is configured to guide the medical device out in a direction different from the insertion/pulling-out direction of the guide wire.
8. The medical device system according to claim 7 ,
wherein the guide-wire fixing portion is provided with a holding portion that is configured to hold and fixe the guide wire, and the operation unit that causes the holding portion to move in the insertion/pulling-out direction with respect to the port member.
9. The medical device system according to claim 6 , wherein the anchor portion comprises a balloon that is configured to be dilated to fix the position of a portion of the guide wire relative to the body lumen.
10. The medical-device system according to claim 6 , wherein the medical device comprises a bladed balloon.
