Method of using interventional medical device system having an elongation retarding portion
First Claim
1. A method of using an interventional medical device system in a body vessel, comprising:
- providing a generally hollow tubular system comprising;
(a) a distal end portion, (b) a proximal end handle portion, (c) an intermediate portion between the distal end portion and the proximal end handle portion, said intermediate portion comprising a spiral having a plurality of turns and at least one bridge member between two adjacent turns, and (d) an actuation member fixedly connected to the proximal end handle portion and extending generally from an interior of the proximal end handle portion of the system to an interior of the distal end portion of the system;
introducing a portion of the distal end portion of the system into a body vessel;
positioning the distal end portion of the system generally adjacent to a target location within the body vessel;
moving the proximal end handle portion proximally with respect to the distal end portion; and
thereby breaking the bridge member and proximally moving the actuation member.

Abstract
Use of an interventional medical device system operable while within a body vessel is provided with a generally hollow tubular proximal portion, distal portion, and intermediate portion. The proximal portion and at least part of the distal portion remains outside of the body in use, with the remainder of the distal portion positioned within the body. The intermediate portion includes a spiral ribbon having adjacent turns, with at least one frangible bridge member between two adjacent turns. The proximal and distal portions are movable away from each other by elongating the spiral ribbon and, eventually, breaking the frangible bridge member. According to the method of using such a system to deploy an implantable medical device, such as an embolic coil, an actuation member is moved proximally with the proximal portion to disengage a bond or joint between the actuation member and the implantable medical device.

7. A method of using an interventional medical device system in a body vessel, comprising:
-
providing a generally hollow tubular system comprising;
(a) a distal end portion, (b) a proximal end handle portion, (c) an intermediate portion between the distal end portion and the proximal end handle portion, said intermediate portion comprising a spiral-cut section of a hypotube having a plurality of turns and with an interrupted spiral-cut section having a plurality of frangible bridge members between two adjacent turns, and (d) an actuation member fixedly connected to the proximal end handle portion and extending generally from an interior of the proximal end handle portion of the system to an interior of the distal end portion of the system;said providing further including providing bridge members out of axial alignment with a bridge member immediately adjacent thereto; introducing a portion of the distal end portion of the system into a body vessel; positioning the distal end portion of the system generally adjacent to a target location within the body vessel; moving the proximal end handle portion proximally with respect to the distal end portion; and thereby breaking bridge members and proximally moving the actuation member, and the bridge members retard axial extension of the spiral ribbon thereat in response to application of a force applied to the intermediate portion from the proximal portion. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
