A jointless prosthetic foot having a leaf spring which has a distal footfall section, a connecting section and a proximal attachment section which extends in an anterior-posterior direction and to which an attachment adapter can be fixed. The attachment adapter is mounted such as to be movable along a convexly curved path in the anterior-posterior direction.

The invention relates to an orthopedic knee joint, comprising an upper part (2), on which upper connecting means (20) are disposed, a lower part (3) pivotally supported on the upper part (2), connecting means for orthopedic components (4), and a stop ( ) for delimiting an extension movement, wherein the stop (7) is configured displaceably and coupled to an adjusting device (64), which is coupled to a control device (6), which actuates the adjusting device (64) as a function of sensor data and changes the position of the stop (7).

The disclosure provides apparatus and methods of use pertaining to a bidirectional biomechanical prosthetic finger assembly. In one embodiment, the assembly includes an eccentric metacarpophalangeal (MCP) pivot configured for swivelable attachment to a hand of a user, a distal coupler, and an articulation assembly rotatively coupled therebetween. A ring configured to receive a user's residual finger is disposed upon the articulation assembly, and may be adjusted to a target location based on a length of the residual finger. The articulation assembly is configured to utilize vertical movements of the residual finger within the ring to articulate the distal coupler within a plane parallel to an x-z plane, and the MCP pivot is configured to utilize lateral movements of the residual finger within the ring to articulate the distal coupler within a plane parallel to an x-y plane. Other embodiments are also disclosed.

Various aspects of the present disclosure characterize apparatuses and/or methods as may be implemented with a variety of prosthetic components and applications. As may be consistent with one or more embodiments described herein, movement parameters pertaining to movement of a user of a prosthetic foot are sensed as the user travels along a surface, with the prosthetic foot having a front ball region and a rear heel region for respectively contacting the surface. A state of movement of the user, including a speed at which the user is travelling along the surface, is determined based on the sensed movement parameters. Utilizing a mechanical actuator, the prosthetic foot is dynamically positioned in response to the speed at which the user is travelling along the surface, by manipulating the mechanical actuator to move the rear heel region relative to the front ball region based on changes in the speed.

The present disclosure illustrates a prosthetic foot that may reduce snagging on external obstacles. In some embodiments, a prosthetic foot includes a symmetric wear member that is rotatable to allow a user to alter an orientation of the symmetric wear member for even wear. A cuff may couple to the symmetric wear member, and include the proximal end comprising a receptacle with an opening having an adjustable diameter. The receptacle may be sized and shaped to receive and selectively retain the prosthesis pylon by adjusting the diameter of the opening. The prosthetic foot may further include a vertical adjustment mechanism that selectively alters a depth of the receptacle of the cuff to vertically displace the prosthesis pylon.

An adjustable seal system, seal component for use in the system, and method are provided for forming a sealing interface between a residual limb and a prosthetic socket. The seal component is selectively placed over the outer surface of a suspension liner including a plurality of seal bands, which the seal component may removably and securely engage.

A control system for control of a prosthetic device having a plurality of actuators receives an orientation signal indicative of a desired movement. The control system evaluates whether the prosthetic device may move as desired with a current angle of rotation and commands at least one actuator to move the prosthetic device as desired by maintaining the current angle of rotation or by adjusting the angle of rotation if the prosthetic device cannot move as desired with the current angle. The control system may alternate between commanding a first subset of actuators and a second subset of actuators each time the orientation signal is indicative of a neutral position. The control system may include a position sensor and a compliance sensor and may command at least one actuator based on a combination of positional control using the position sensor and force control using the compliance sensor.

A prosthetic system includes a prosthetic foot having an upper foot element with a concave-forward facing portion and foot portion extending forwardly therefrom. An intermediate foot element is disposed below the upper foot element and has a front portion coupled to the foot portion of the upper foot element. A lower foot element is disposed below the intermediate foot element. A pump system is coupled to the prosthetic foot and comprises a pump mechanism including a housing defining a cavity, and a membrane situated in the cavity. The pump mechanism is movable between an original configuration and an expanded configuration. An arm member is connected to the pump mechanism and operatively coupled to the intermediate foot element. The arm member is arranged to move the pump mechanism toward at least the expanded configuration upon movement of the intermediate foot element relative to the upper foot element.

A prosthesis or orthosis for a joint, such as an ankle, which includes a first body, a second body, and an articulated joint between the first and second bodies, the articulated joint allowing the rotation of the first and second bodies with respect to one another around a joint rotation axis. It further includes a locking mechanism configured to selectively lock the rotation between the first and second bodies in one direction, when it is in a locked configuration, and a transmission mechanism such that a rotation of the joint rotation axis generates a movement of a lockable part of the locking mechanism. The axis of the movement of the lockable part is shifted relative to the joint rotation axis and the transmission mechanism includes a reducer configured to reduce effort to lock the rotation of the first body with respect to the second body.

A percutaneous collar is made up of a central rigid ring and a flexible mesh inside a microporous silicone disc. The volume of the disc has a three-dimensional network of interconnected micropores forming microchannels connecting both external faces of the disc through the external micropores to the internal flexible mesh wherein the flexible mesh is formed by crossed longitudinal and radial elements or plates which form a plurality of holes.
