Patent number: 9078735Abstract: An external orthotic device increases comfort, stability, and motion control of the ankle and/or foot. An outer shell comprises separate medial and lateral portions, attached to each other only by a flexible/hinge connector that extends between and is preferably anchored to each of the portions in an under-the-foot region of the shell. This connector retains the bottom end of the shell portions together, but allows the shell portions to pivot or otherwise move relative to each other with the bottom-of-the-foot connector as the pivot axis. This pivoting allows the shell to open wide for donning and doffing of the orthotic device and for adjusting the closeness of the two portions to tighten the two portions on the wearer. Strap(s) or other retainer may tighten the medial and lateral portions together around a liner into which the wearer inserts his/her foot.Type: GrantFiled: January 25, 2013Date of Patent: July 14, 2015Assignee: COYOTE DESIGN & MANUFACTURING, INCInventor: Dale Perkins

Patent number: 8409298Abstract: An attachment system secures a residual limb to an artificial limb in a comfortable and substantially non-rotational manner. The attachment system offers proximal anchoring of the residual limb in a hard socket, by connecting a side surface of a residual limb liner to the side surface of the socket. Preferably, this connection is accomplished using an extension member extending from the liner through a portion of the socket interior, through the socket wall, and attaching to a latch mechanism. The preferred attachment system requires no clearance in the bottom of the socket well because neither the extension member nor the latch mechanism is located between the distal end of the residual limb/liner and the bottom of the well. The attachment system is preferably disposed entirely along the side of the limb and the side of the socket.Type: GrantFiled: December 14, 2010Date of Patent: April 2, 2013Inventors: Dale Perkins, Matt Perkins

Patent number: 8343233Abstract: A valve system for a prosthetic hard socket includes an elastomeric valve member that rests in a closed position that seals against a valve housing surface, and opens at a low “crack” or “pop” pressure, for example, when the pressure inside the distal region of the socket well is 1-3 psi above the air pressure outside the hard socket. The elastomeric valve member exhibits a very accurate and reproducible response at the low crack pressure, and, in addition, sound dampening and/or filtration pads further reduce sound and fouling of the preferred elastomeric valve member. The valve may be installed without leaks even on highly-curved thin-walled sockets, as the broad base of the valve is adhesively attached to the outside of the socket, and optionally a rearward protrusion extends into a hole in the socket without protruding into the socket well.Type: GrantFiled: June 29, 2010Date of Patent: January 1, 2013Inventors: Matt Perkins, Dale Perkins

Publication number: 20120143352Abstract: A prosthetic hard socket has a modified curvature and/or shape that improves rotational control, comfort, and range of motion including even full extension or hyperextension. The hard socket eliminates or de-emphasizes the patellar bar, to eliminate or reduce pressure on the wearer's patellar tendon, and enhances support of the anterior tibial condyle and/or tibial tubercle. Thus, the patellar tendon preferably is not weight-bearing. A lowered socket edge and/or a gap in the socket wall in the region of the patellar tendon prevents the hard structure of the socket from directly supporting or pressing upon the patellar tendon. Inwardly-protruding regions on each side of the lowered edge/gap help “capture” or otherwise press on a portion of the tibia. A flexible and/or cushioning member may be placed in the gap/trough.Type: ApplicationFiled: December 13, 2011Publication date: June 7, 2012Applicant: COYOTE DESIGN & MANUFACTURING, INCInventor: DALE PERKINS

Publication number: 20110295386Abstract: A valve system regulates the air pressure in the space(s) between a residual limb, or liner-covered limb, and a hard socket of an external prosthesis, for example, for improving donning and doffing the prosthesis, and/or during walking and other normal use of the prosthesis. The valve system may include a manually-controlled air outlet and inlet valve that may be installed on a distal region of a hard socket, and/or an automatic one-way outlet valve. The manually-controlled valve is preferably opened and closed by twisting of a handle portion of the valve system, wherein partial rotation of the handle portion relative to the base portion of the valve system creates slight separation of the handle and base portions to form a gap through which may pass air from the well of the socket. This simple twisting, or partial rotation, provides a valve that stays open hands-free, so that the wearer may open the valve and then use his/her hands to don or doff the prosthesis.Type: ApplicationFiled: August 9, 2011Publication date: December 1, 2011Applicant: COYOTE DESIGN & MANUFACTURING, INCInventors: MATT PERKINS, DALE PERKINS

Patent number: 7993413Abstract: A valve system regulates the air pressure in the space(s) between a residual limb, or liner-covered limb, and a hard socket of an external prosthesis, and may include a manually-controlled air outlet and inlet valve on a distal region of a hard socket, and/or an automatic one-way outlet valve. The manually-controlled valve is opened and closed by partial rotation/twisting of a handle portion, which creates slight separation of the handle and base portions through which may pass air. The handle and base are prevented from becoming entirely separated during normal use by a snap-fit of the base onto the handle that retains the ability of the handle and base to rotate relative to each other by means of a ramp system, and a stop(s) that limit(s) the amount of relative rotation of the handle and base portions of the valve.Type: GrantFiled: February 2, 2009Date of Patent: August 9, 2011Inventors: Matt Perkins, Dale Perkins

Publication number: 20110022182Abstract: A valve system may attach to the distal area of a prosthetic hard socket without leaks, in spite of the high amount of curvature of the distal area. The valve stem/member of the valve system slides to, or rests in, a closed position that seals against a valve housing surface. The valve is adapted for a low “crack” or “pop” pressure, for example, when the pressure inside the distal region of the socket well is 1-3 psi above the air pressure outside the hard socket. An elastomeric valve member is preferably used that exhibits a very accurate and reproducible response at the low crack pressure, and, in addition, sound dampening and/or filtration pads may be used to further reduce sound and fouling of the preferred elastomeric valve member. The preferred valve gives repeated, consistent, and quiet performance, which helps prevent uncomfortable and/or high-noise-producing swings in the pressure inside the socket well.Type: ApplicationFiled: June 29, 2010Publication date: January 27, 2011Applicant: COYOTE DESIGN AND MANUFACTURING, INC.Inventors: MATT PERKINS, DALE PERKINS
