Abstract
An implantable intramuscular lead system, such as for use as a gastric lead, and method of use in which electrodes along the lead are imbedded in tissue. First and second anchors are mounted on an elongate lead. At least the second anchor is movable along the length of the lead relative to the first anchor to capture the tissue between the anchors so that the lead is retained in position. The system facilitates implantation of the lead in tissue, and may be particularly suited for minimally invasive implantation, such as laparoscopically.
Claims51
An implantable intramuscular lead system comprising:
- at least one elongate lead having a length, opposite ends;
- a first anchor mounted on the lead;
- and
- a second anchor mounted on the lead for movement along the length of the lead relative to the first anchor to capture the tissue between the anchors so that the lead is retained in position.
An implantable therapy delivery system, comprising:
- an implantable therapy delivery device;
- at least one elongate therapy delivery element coupled to the implantable therapy delivery device, the therapy delivery element having a length and opposite ends;
- a first anchor mounted on the therapy delivery element;
- and
- a second anchor mounted on the therapy delivery element for movement along the length of the therapy delivery element relative to the first anchor to capture the tissue between the anchors so that the therapy delivery element is retained in position for delivery of a therapy.
A method of implanting a therapy delivery system, comprising the following steps:
- providing an elongate therapy delivery element having a length and opposite ends, a first anchor mounted on the therapy delivery element;
- and a second anchor mounted on the therapy delivery element for movement along the length of the therapy delivery element relative to the first anchor;
- introducing therapy delivery element through tissue so that the first anchor engages the tissue;
- advancing the second anchor along the therapy delivery element to capture the tissue between the first and second anchors, thereby retaining the therapy delivery element in position for delivery of a therapy;
- and
- coupling and implanting an implantable therapy delivery device to the therapy delivery element.
A method of implanting an implantable medical lead, comprising the following steps:
- providing an elongate medical lead having a length and opposite ends, a first anchor mounted on the lead;
- and a second anchor mounted on the lead for movement along the length of the lead relative to the first anchor;
- introducing lead through tissue so that the first anchor engages the tissue;
- advancing the second anchor along the lead to capture the tissue between the first and second anchors, thereby retaining the lead in position for delivery of a therapy;
- and
- coupling and implanting an implantable pulse generator to the lead.
A method of implanting an implantable gastric lead in gastric tissue, comprising the following steps:
- providing an elongate medical lead having a length and opposite ends, a first anchor mounted on the lead;
- and a second anchor mounted on the lead for movement along the length of the lead relative to the first anchor;
- introducing lead through gastric tissue so that the first anchor engages the gastric tissue;
- advancing the second anchor along the lead to capture the gastric tissue between the first and second anchors, thereby retaining the lead in position for delivery of a therapy or sensing of gastric activity.
