Abstract
A device (110) for insertion into a human or animal body has a surface (610) which at least partially bears a surface structure (140, 140′), wherein the coefficient of static friction between the surface structure (140, 140′) and an interface within the body is anisotropic.

A device (110) for insertion into a human or animal body, the device including an outer surface (610) at least partially bearing a surface structure (140, 140′), wherein the coefficient of static friction between the surface structure (140, 140′) and an interface within the body is anisotropic, the device (110) further including control means mounted on the outer surface (610) for controlling a direction of displacement (150, 150′) of the device (110), the control means having a length extending from the surface (610) which is greater than a maximum diameter of the device, the maximum diameter being measured between the furthermost opposing points on the outer surface (610) of the device.
A device (110) for insertion into a human or animal body wherein:
- a. the device is defined by one of:
- (1) an implant, or
- (2) a carrier device configured to transport an implant within a body;
- b. the device includes a surface (610) having elements (620, 630, 640, 650, 660, 710, 720) extending therefrom at an incline relative to the surface, the elements:
- (1) providing an anisotropic coefficient of static friction between the surface structure (140, 140′) and an interface within the body, and
- (2) being configured to cancel the anisotropic coefficient of static friction after insertion within the body, without deformation of the device's surface.
A device (110) for insertion into a human or animal body wherein:
- a. the device is defined by one of:
- (1) an implant, or
- (2) a carrier device configured to transport an implant within a body;
- b. the device includes a surface (610) having elements (620, 630, 640, 650, 660, 710, 720) extending therefrom at an incline relative to the surface, the elements:
- (1) providing a coefficient of static friction between the surface structure (140, 140′) and an interface within the body wherein the coefficient is:
- (a) minimal in a first direction of displacement (160) of the device (110) with respect to the interface, and
- (b) greater than the minimal coefficient of static friction in directions of displacement oriented at greater than 90 degrees from the first direction of displacement;
- and
- (2) being removable from the device (110).
