Problems solved by technology

The main concerns when using the AMS800 are: tissue erosion around the urethra due to constant pressure; tissue atrophy and irritation at the site of the expandable cuff; and for emergency procedures for repair, the device should remain closed in case of mechanical failure Location
[0022] As a result, currently no good solution exists, either commercially or in the literature, for the implantation of battery-operated devices that frequently press on the organ, whereby the battery can run for two years without recharging

example

[0157] refer to figure 1 and 2 , one embodiment of the medical device of the invention for treating urinary incontinence comprises a contractile element 100 designed, for example, to partially surround a hollow part of the urethra. To simplify the drawing, only one retractable element 100 is shown. But the medical device of the present invention may comprise a collapsible structure comprising at least two collapsible elements 100, for example adapted to be placed around the hollow part of the urethra, and coupled by a connecting element.

[0158] The contractile element 100 comprises a strap 102 designed to surround at least simultaneously the hollow part of the organ to be contracted. The strap 102 is made of silicone, PTFE, PLA, PUR, PMMA, (POM), HDPE LDPE or combinations thereof to reduce friction when the strap is tightly wrapped around the organ. Other suitable materials can be used, such as metal.

[0159] The medical device also includes an actuator, which is placed...

Abstract

The present invention relates to a medical device comprising an artificial contractile structure which may be advantageously used to assist the functioning of a hollow organ. Said medical device comprises an artificial contractile structure comprising at least one contractile element (100) adapted to contract an organ, in such way that said contractile element (100) is in a resting or in an activated position, at least one actuator designed to activate said contractile structure, and at least one source of energy for powering said actuator. The ratio 'current which is needed to maintain the contractile element in its activated position / current which is needed to change the position of the contractile element' is less than 1 / 500, preferably less than 1 / 800, and more preferably less than 1 / 1000.

Description

technical field [0001] The present invention relates to a medical device comprising an artificial contractile structure activated by an actuator, which can advantageously be used to assist the work of an organ such as a sphincter or the heart. More specifically, it can be used to move or shrink a hollow or tubular portion of the body so as to reduce its diameter. Background technique [0002] It is known to use man-made structures to assist muscle contraction. This structure is adapted to assist the atria or ventricles to contract, or to assist or replace the natural sphincter. The use of this artificial sphincter has increased in recent years, as fecal and urinary incontinence now affects more than 10% of people over the age of 60, and increases significantly in patients over the age of 80. To treat urinary and fecal incontinence, several medical or surgical solutions have been developed. Overall, the outcomes of surgical treatment of urinary and fecal incontinence are c...
