Abstract
A prosthetic or orthotic sleeve includes a distal portion, a proximal portion, and a center portion extending between the distal and proximal portions. An external surface of the sleeve includes at least one peripheral profile portion having an undulating wall thickness defined as a plurality of projections arranged in a pattern.
Claims19
An orthotic or prosthetic sleeve, comprising:
- a tubular shaped body having open ends and the entire body defining a solid wall thickness that extends along an axis, the body having a distal portion, a proximal portion, and a center portion extending between the distal and proximal portions, the body adapted and sized for receiving a residual limb;
- wherein an external surface of the body defines at least one peripheral profile portion having an undulating solid wall thickness;
- wherein an internal surface of the body forms at least one ring projecting towards the body axis, the internal surface defining a generally continuous even surface outside the at least one ring;
- wherein the at least one peripheral profile portion and the at least one ring are formed independently from one another, and from the thickness of the body.

An elasticized sleeve having internal and external surfaces, comprising:
- a tubular shaped body, open at both ends, extending along an axis, and formed of an elasticized fabric layer and an elastomer polymeric layer that is discretely secured to the fabric layer, the body having a distal portion, a proximal portion, and a center portion extending between the distal and proximal portions, the elasticized fabric defining the external surface of the body;
- wherein an internal surface of the tubular sleeve is entirely coated with the elastomer polymeric layer that defines the internal surface of the body, the elasticized fabric layer being secured to the elastomer polymeric layer and coextensive therewith;
- wherein an external surface of the body defines at least one peripheral profile portion having an undulating solid wall thickness;
- wherein the elastomer polymeric layer forms at least two rings of solid wall thickness defined along the internal surface of the body, and the at least two rings projecting towards the body axis;
- wherein the at least one peripheral profile portion and the at least two rings are formed independently from one another;
- and
- wherein the at least two rings includes a first ring located within the proximal portion of the body, and a second ring located within the distal portion of the body.
