Abstract
A medical device system includes an elongate sheath defining a lumen extending within the elongate sheath. A coupler mechanism is slidingly disposed within the lumen, the coupler mechanism including a proximal coupler and a distal coupler. An elongate member is secured to and extends proximally from the proximal coupler. An implantable medical device (IMD) is secured to and extends distally from the distal coupler. The distal coupler remains secured to the proximal coupler while the coupler mechanism remains within the lumen, and the distal coupler releases from the proximal coupler, thereby releasing the IMD, when the coupler mechanism is exterior to the lumen.
Claims20
A medical device system, comprising:
- an elongate sheath defining a lumen extending within the elongate sheath;
- a coupler mechanism slidingly disposed within the lumen, the coupler mechanism including a proximal coupler and a distal coupler;
- an elongate member secured to and extending proximally from the proximal coupler;
- an implantable medical device (IMD) secured to and extending distally from the distal coupler;
- wherein the distal coupler remains secured to the proximal coupler while the coupler mechanism remains within the lumen;
- and
- wherein the distal coupler releases from the proximal coupler, thereby releasing the IMD, when the coupler mechanism is exterior to the lumen.
A system for delivering an embolic coil, the system comprising:
- an elongate sheath defining a lumen extending within the elongate sheath;
- an elongate member extending through the lumen;
- and
- a coupler mechanism slidingly disposed within the lumen and releasably coupling an embolic coil to the elongate member;
- the coupler mechanism adapted to prevent the embolic coil from separating from the elongate member while the coupler mechanism is radially constrained by the elongate sheath;
- the coupler mechanism adapted to allow the embolic coil to separate from the elongate member when the coupler mechanism is no longer radially constrained by the elongate sheath.
An embolic treatment system, comprising:
- an elongate sheath defining a lumen extending within the elongate sheath;
- a coupler mechanism slidingly disposed within the lumen, the coupler mechanism including a proximal coupler and a distal coupler;
- an elongate member secured to and extending proximally from the proximal coupler;
- an embolic coil secured to and extending distally from the distal coupler;
- wherein the distal coupler remains secured to the proximal coupler while the coupler mechanism remains within the lumen;
- and
- wherein the distal coupler releases from the proximal coupler, thereby releasing the embolic coil and the proximal coupler, when the coupler mechanism is exterior to the lumen.
