Abstract
The present disclosure sets forth a guiding tube for placing medical implants within body tissue. The guiding tube includes an elongated, dimensionally stable tubular body encompassing an inner channel adapted to receive a medical implant wherein the tubular body has at least one electromagnetic element, the element configured to exert an electromagnetic force on at least one magnetic element of the medical implant inserted into the inner channel of the guiding tube. The medical implant includes a stimulation lead having at least one directional electrode with an elongated body insertable into an inner channel enclosed by a tubular body of the guiding tube.
Claims12
A guiding tube for placing medical implants within body tissue, comprising:
- an elongated, relatively stiff tubular body encompassing an inner channel adapted to receive a medical implant;
- wherein the relatively stiff tubular body comprises at least one electromagnetic element at a distal portion of the guiding tube, which is configured to generate a directional field within the inner channel;
- wherein the relatively stiff tubular body connects the at least one electromagnetic element to at least one tracking marker coupled to the relatively stiff tubular body at a proximal portion of the relatively stiff tubular body, the at least one tracking marker being identifiable by a medical tracking system, thereby maintaining the directional field in a single predefined orientation with respect to the at least one tracking marker.
A guiding tube for placing medical implants within a patient's body, comprising:
- an elongated, relatively stiff tubular body having an inner channel adapted to receive a medical implant including at least a stimulation lead having at least one directional electrode;
- wherein the relatively stiff tubular body comprises at least one electromagnetic element, the at least one electromagnetic element generating a directional field within the inner channel;
- wherein the directional field has a predefined orientation to align the medical implant with respect to the relatively stiff tubular body;
- wherein the relatively stiff tubular body comprises a proximal interface section adapted to connect to a support structure for holding the electromagnetic element in a spatially fixed orientation with respect to the patient's body.
A guiding tube for placing medical implants within a patient's body, comprising:
- an elongated, relatively stiff tubular body having an inner channel adapted to receive a medical implant;
- wherein the relatively stiff tubular body comprises at least one electromagnetic element, the at least one electromagnetic element generating a directional field within the inner channel;
- wherein the directional field has a predefined orientation to align the medical implant with respect to the relatively stiff tubular body;
- the medical implant including at least a stimulation lead having at least one directional electrode;
- a medical tracking system and at least one medical tracking marker connected to the relatively stiff tubular body at a portion of the relatively stiff tubular body that is adapted to remain outside the patient's body, the medical tracking system identifying the orientation of the at least one medical tracking marker.
