Filed:

Jul 29, 2003

Appl. No.:

10/630219

Inventors:

Michael Schrom - Wyoming Township MN, US
Charles Lehman - Minneapolis MN, US
Mark Schrom - Hugo MN, US

Assignee:

MICRONET MEDICAL, INC. - White Bear Lake MN

International Classification:

A61N001/05

US Classification:

607116000

Abstract:

An implantable lead and lead body, method of manufacturing the same, and a system and method for stimulating a portion of a body is disclosed. In one advantageous embodiment, a lead body assembly is formed by placing an inner layer of extrusion material on a mandrel, wrapping a plurality of conductors coated with extrusion material around the inner layer, and placing an outer layer of extrusion material over the plurality of conductors. Heat shrink tubing is placed over the lead body assembly and the lead body assembly is heated to melt the extrusion material. The melted extrusion material is compressed around the plurality of conductors. The assembly is then cooled and the heat shrink tubing is removed. The solidified extrusion material forms a protective wall that encapsulates the plurality of conductors in the lead body.

Abstract:

An implantable medical lead and lead body, method of manufacturing the same, and a system and method for stimulating a portion of a body is disclosed. In one advantageous embodiment, a lead body assembly is formed by preparing a first layer unitary body comprising a first plurality of conductors. An inner layer of extrusion material is placed on the first layer unitary body. A second plurality of conductors coated with extrusion material is placed on the inner layer. An outer layer of extrusion material is placed over the second plurality of conductors. Heat shrink tubing is placed over the assembly and the assembly is heated to melt the extrusion material. The extrusion material is compressed around the conductors. The assembly is cooled and the heat shrink tubing is removed. The solidified extrusion material forms a protective wall that encapsulates the first and second plurality of conductors in the lead body.

Abstract:

An implantable medical lead and lead body, method of manufacturing the same, and a system and method for stimulating a portion of a body are disclosed. A lead body assembly is formed by preparing a first layer unitary body comprising a first plurality of conductors wound in a first direction. An inner layer of extrusion material is placed on the first layer unitary body. A second plurality of conductors coated with extrusion material is placed on the inner layer. The second plurality of conductors is wound in a second opposite direction. An outer layer of extrusion material is placed over the second plurality of conductors. Heat shrink tubing is placed over the assembly. The extrusion material is heated and melted and compressed around the conductors. When the heat shrink tubing is removed, the solidified extrusion material forms a protective wall that encapsulates the conductors in the lead body.

Charles Lehman - St. Louis Park MN, US

International Classification:

A61M 16/06

US Classification:

12820621, 12820525

Abstract:

Composite mask apparatus for providing positive pressure airway therapies are disclosed. The composite mask apparatus include an upper body and a lower body. The lower body is secured to a lower portion of the upper body. The upper body supports at least a portion of the lower body. A first branch of the upper body may be secured to a first tube of the lower body and a second branch of the upper body may be secured to a second tube of the lower body. An airway interface may be in fluid communication with a first lumen of the first tube and may also be in fluid communication with a second lumen of a second tube.
