Abstract
Disclosed is an implant intended to be introduced into a human or animal body cavity, and includes two walls intended to grip between them a biological protuberance present in the cavity in order to attach the implant to the biological protuberance. Each wall includes a structural element having corrugations such that the structural element is folded up on itself several times, enabling the wall to be folded up before the introduction of the implant, then deployed inside the cavity.
Core Innovation
The invention relates to an implant for medical use intended to be introduced into a cavity of a human or animal body. The implant includes at least one clip with two parallel planar walls whose planes extend substantially facing each other so the two parallel planar walls are configured to grip a biological protuberance present in the cavity in order to attach the implant to the biological protuberance.
Each of the two parallel planar walls includes a structure element having longitudinal undulations so that the structure element is folded up more than one time on itself. This configuration allows each wall to be folded up before the introduction of the implant, and then deployed inside the cavity, including embodiments where the deployment is based on shape memory material and/or superelasticity activated above a predetermined temperature threshold.
The disclosed embodiments further include optional stabilizers with a meshed, flattenable structure and fluid permeability, as well as anti-inflammatory and/or antimicrobial and therapeutic coatings. A sensor may be provided for monitoring a biological parameter, with wireless communication and alerting, and the clip may include wall height profiles and structural reinforcement elements along wall edges.
Claims Coverage
The document provides one independent claim, clm-00001, describing the implant clip and multi-folded longitudinally undulated structure elements that enable pre-folding and deployment inside a cavity. Dependent refinements specify particular undulated structure constructions, material types, surface coatings, and optional quantitative and sensor-related features.
Parallel planar-wall clip gripping a biological protuberance in a body cavity
The implant for medical use intended to be introduced into a cavity comprises at least one clip comprising two parallel planar walls configured so that the planes extend substantially facing each other to grip therebetween a biological protuberance present in the cavity to attach the implant to the biological protuberance.
Longitudinally undulated multi-folded structure element for pre-folding and in-cavity deployment
Each of the two parallel planar walls includes a structure element having longitudinal undulations so that the structure element is folded up more than one time on itself, allowing each of the two parallel planar walls to be folded up before the introduction of the implant, then deployed inside the cavity.
Temperature-threshold deployment using a shape memory material
Each of the two parallel planar walls includes a structure element in which the structure element uses a shape memory material configured to deploy when exposed to a temperature above a predetermined temperature threshold.
Meander-linked rod/parallel-bar construction enabling multi-folding
The structure element is a rod comprising parallel bars whose ends are connected by meanders and arranged so that each parallel planar wall can be folded up more than one time onto itself by bringing the parallel bars closer to one another.
Superelastic and/or resorbable material for the structure element
The structure element includes a superelastic and/or resorbable material.
Across the independent claim and its main refinements, the inventive subject matter is centered on a clip with two facing parallel planar walls that grip a biological protuberance in a cavity, combined with longitudinally undulated structure elements folded multiple times for pre-folding and then deployment inside the cavity. Further refinements include temperature-threshold deployment with shape memory material, specific meander-linked rod/parallel-bar multi-fold construction, and material options including superelastic and/or resorbable materials.
Stated Advantages
Allows the two parallel planar walls to be folded up before introduction and then deployed inside the cavity.
Provides attachment to a biological protuberance by gripping it between substantially facing parallel planar walls.
Enables deployment based on shape memory and/or superelasticity activated above a predetermined temperature threshold.
Documented Applications
Use as a medical implant introduced into a cavity of a human or animal body, including described use in the nasal cavity with two vertically stacked clips to secure the middle and inferior nasal conchae and rationale related to reducing concha lateralization.
