Abstract

Embodiments of the present disclosure include medical apparatus, and related methods thereof. The apparatus may include a longitudinally extending lead, at least one electrode, an anchor component, and a control module. The lead may include a distal end and a proximal end. The at least one electrode may be coupled to the lead, wherein the at least one electrode may be disposed on the distal end of the lead. The anchor component may be disposed in the lead proximate of the at least one electrode. The anchor component may include solder. The control module may be operably coupled to the proximal end of the lead and may be configured to deliver energy to the at least one electrode.

First claim

1 . An apparatus, including:
a longitudinally extending lead having a distal end and a proximal end; at least one electrode coupled to the lead, wherein the at least one electrode is disposed on a distal end of the lead; an anchor component disposed on the lead proximate of the at least one electrode, the anchor component comprising solder; and a control module operably coupled to the proximal end of the lead, the control module being configured to deliver energy to the at least one electrode.

2 . The apparatus of claim 1 , wherein the solder includes at least one of polypeptides, nano-peptides, albumin, collagen, elastin, fibrin, protein derivatives, polysaccharides, or chitosan.

3 . The apparatus of claim 1 , wherein the solder includes two or more of polypeptides, nano-peptides, albumin, collagen, elastin, fibrin, protein derivatives, polysaccharides, or chitosan.

4 . The apparatus of claim 1 , wherein the solder includes at least one of an energy absorber, a photosensitizing dye, or a synthetic polymer.

5 . The apparatus of claim 1 , wherein the anchor component includes a mesh.

6 . The apparatus of claim 1 , wherein the anchor component includes at least one radial extension comprising at least one of a fin, a perforated fin, or a sectioned fin.

7 . The apparatus of claim 1 , wherein the lead includes a central lumen extending therethrough.

8 . The apparatus of claim 7 , further comprising:
a longitudinally extending energy transmission element having an energy transmitter positioned at a distal end thereof, the energy transmission element sized for insertion through the central lumen, and wherein the energy transmitter is configured to emit energy at a wavelength sufficient to bond the solder to tissue.

9 . The apparatus of claim 8 , wherein the lead is comprised of material configured to pass the wavelength of emitted energy therethrough.

10 . The apparatus of claim 1 , wherein the at least one electrode is an electrode array comprising between two and twelve electrodes.

11 . A method of electrical stimulation, comprising:
delivering a longitudinally extending lead into a body of a patient, the lead comprising at least one electrode and an anchor component disposed on the lead proximate of the at least one electrode, the anchor component comprising solder; positioning a distal end of the lead such that the at least one electrode is proximate a target tissue site; activating an energy transmitter to emit energy therefrom; directing the emitted energy toward the solder; and bonding the lead adjacent to the target tissue site via the solder.

12 . The method of claim 11 , wherein the lead includes a central lumen, and directing the emitted energy toward the solder includes passing the energy transmitter within the central lumen.

13 . The method of claim 11 , further comprising:
delivering a sheath with a central lumen over the lead, the sheath including an energy transmitter therein, wherein directing the emitted energy toward the solder includes positioning the energy transmitter of the sheath adjacent the solder.

14 . The method of claim 11 , further comprising:
after the bonding, transmitting electrical stimulation to the at least one electrode from a control module, wherein the control module is implanted in the body of the patient.

15 . The method of claim 11 , wherein the solder includes at least one of an energy absorber, a photosensitizing dye, or a synthetic polymer.

16 . The method of claim 11 , wherein the anchor component includes a mesh.

17 . The method of claim 11 , wherein the anchor component includes at least one radial extension comprising at least one of a fin, a perforated fin, or a sectioned fin.

18 . The method of claim 13 , further including:
injecting solder through at least one solder lumen of the sheath.

19 . An apparatus, including:
a longitudinally extending lead having a distal end and a proximal end; at least one electrode coupled to the lead; an anchor component coated or embedded directly onto the lead proximate of the at least one electrode, the anchor component comprising solder; wherein the solder includes at least one of an energy absorber or a photosensitizing dye, and wherein the solder is configured to bond to tissue upon excitation via a bonding energy source.

20 . The apparatus of claim 19 , further including:
a control module operably coupled to the proximal end of the lead, the control module being configured to deliver stimulation energy to the at least one electrode, the control module configured for implantation into a body of a patient;
wherein the bonding energy source includes at least one of a laser, a light-emitting-electrode, a radio-frequency generator, a microwave generator, a radiation generator, and a cold-plasma source.
