Abstract:
1. A medical device for fixing a component to body tissue in a human body, the medical device comprising: a) a flexible, controllably bendable tube having a lumen therethrough and extending from a bendable tube distal region to a bendable tube proximal region; b) a first handle extending from a first handle proximal region to a first handle distal region operably coupled to the controllably bendable tube, wherein a handle lumen extends from a handle lumen proximal end at the first handle proximal region to a handle lumen distal end in communication with the controllably bendable tube lumen, and wherein the handle lumen in communication with the controllably bendable tube lumen have a combined first length; c) a lead body having a second length and comprising an electrical conductor extending from a lead proximal portion to a lead distal portion with at least the lead distal portion having a first longitudinal axis; d) a lead head comprising an annular sidewall extending from a lead head proximal end spaced from a lead head distal end, wherein the annular sidewall surrounds a lead head aperture extending along a second longitudinal axis from the lead head proximal end to the lead head distal end, and wherein the lead distal portion is connected to the lead head proximal end at a point of attachment where the first longitudinal axis of the lead distal portion is radially offset from the second longitudinal axis of the lead head aperture leaving the aperture through the lead head along the second longitudinal axis unobstructed; e) an electrode electrically connected to the lead head to conduct electricity from the electrical conductor to body tissue; and f) a drive shaft having a third length extending from a proximal drive shaft handle to a drive shaft distal portion that is releasably attachable to the lead head to thereby provide the lead body and the drive shaft in a side-by-side relationship with the lead distal portion and the drive shaft distal portion extending through the handle lumen and the controllably bendable tube lumen, and g) wherein the first handle proximal region is manipulatable to position a distal opening of the controllably bendable tube lumen adjacent to a body tissue, and h) wherein the second and third lengths of the respective lead body and drive shaft are longer than the first length of the handle lumen in communication with the controllably bendable tube lumen, such that the drive shaft handle is manipulatable from a position proximate the first handle proximal region to impart rotational movement to the drive shaft and the lead body including the lead head extending out beyond the distal opening of the controllably bendable tube lumen to thereby secure the electrode into body tissue, and i) wherein the drive shaft is then releasable from the lead body and movable in a proximal direction through the controllably bendable tube lumen and the handle lumen to remove the drive shaft therefrom, and j) wherein the first handle and controllably bendable tube are then movable in a proximal direction to slide and separate the handle lumen and the controllably bendable tube lumen over and from the lead body.
