Abstract
In one embodiment, the invention is directed to an implantable medical lead comprising a lead including a proximal end, a distal end, and an electrode. The lead may also include tissue fixation structures on the lead a distance from the electrode, wherein the tissue fixation structures exploit acute and chronic fibrous tissue growth with respect to the lead to enhance fixation of the lead to tissue and thereby secure the electrode in an implanted position. In some cases, the tissue fixation structures may include fibrous growth holes to exploit acute and chronic fibrous tissue growth and advantageously anchor the lead within tissue.
Claims57
An implantable medical lead comprising:
- a lead including a proximal end, a distal end, and an electrode;
- and
- tissue fixation structures on the lead a distance from the electrode, wherein the tissue fixation structures promote fibrous tissue growth with respect to the lead to enhance fixation of the lead to tissue.
An implantable medical device comprising:
- a medical lead including a proximal end, a distal end, and an electrode, and tissue fixation structures defined on the lead a distance from the electrode, wherein the tissue fixation structures increase fibrous tissue growth with respect to the lead to enhance fixation of the lead to tissue and thereby secure the electrode in an implanted position;
- and
- a puncture needle that substantially encapsulates the lead.
An implantable medical device comprising:
- a medical lead including a proximal end, a distal end, and an electrode, and tissue fixation structures on the lead a distance from the electrode, wherein the tissue fixation structures exploit fibrous tissue growth with respect to the lead to enhance fixation of the lead to tissue;
- and
- a control unit coupled to the proximal end.
An implantable medical lead comprising:
- a lead having a proximal end, a distal end, and an electrode;
- and
- means for tissue fixation on the lead a distance from the electrode, wherein the
- means exploits fibrous tissue growth with respect to the lead to enhance fixation of the lead to tissue and thereby secure the electrode in an implanted position.
A method comprising:
- puncturing a hole in an interventricular septum with a puncture needle that encapsulates a medical lead including tissue fixation structures on a lead a distance from an electrode on the distal end of the lead;
- retracting the puncture needle from the punctured hole;
- and
- retracting the medical lead such that the tissue fixation structures are positioned within the interventricular septum.
An implantable medical lead comprising:
- a lead including a proximal end, a distal end, and an electrode;
- and
- tissue fixation structures that extend a distance radially from the lead, wherein the tissue fixation structures exploit fibrous tissue growth with respect to the lead to enhance fixation of the lead to tissue.
