A prosthetic interface includes an orientation assembly, a mounting plate and a load bearing assembly. The orientation assembly includes an anterior frame portion and a posterior frame portion. The anterior frame portion extends over an anterior portion of a torso of a wearer of the prosthetic interface. The posterior frame portion extends over a posterior portion of the torso. The mounting plate is disposed at an intersection of the posterior frame portion and the anterior frame portion. The mounting plate forms a structure to which a prosthetic limb is attachable. The load bearing assembly includes breathable fabric forming a load distribution matrix to distribute a load on the mounting plate over portions of the torso with which the fabric is in contact.

Breathable microframe prosthetic interface

A grinder pump with a self aligning cutter assembly, the grinder pump having an inlet port, a drive shaft and a cutter assembly, the cutter assembly comprising a rotary cutter and a stationary, annular cutter. The rotary cutter is supported for rotation by the drive shaft, and the annular cutter is supported in the inlet port. The rotary cutter has a pair of primary knife members with knife edges, and the annular cutter is supported in the inlet port, the annular cutter having a central bore in which a plurality of internal cutting edges are formed. The rotary cutter is supported in the central bore so its primary knife members are rotated in operational cutting engagement with the internal cutting edges by the drive shaft. The annular cutter is provided a limited range of radial movement and is positioned within the range of movement by the rotary cutter.
