Title (EN) INTERVENTIONAL MEDICAL SYSTEMS AND RETRIEVAL TOOLS THEREOF
(FR) SYSTÈMES D’INTERVENTION MÉDICALE ET OUTILS DE RÉCUPÉRATION ASSOCIÉS
Abstract:
(EN) A tool (600) operable with a catheter (400) in an interventional medical system retrieves a medical device (300) from an implant site, wherein the device (300) includes an attachment feature (310) that forms an annular recess (31) to be engaged by a lasso (620) of the tool (600) for snaring the device (300), and a distal-most sidewall (420) of the catheter (400) defines a receptacle (420R) into which the snared device (300) is retrieved. A guide (610) of the tool (600) includes a sidewall (610S) defining a lumen (601) in which the lasso (620) extends for deployment out from a distal opening (62) thereof, to snare and retrieve the implanted device (300). The sidewall (230, 420, 61, 710S) establishes a radial offset between the guide lumen distal opening (62) and the distal-most sidewall (610S) of the catheter (400), when the guide lumen distal opening (62) and a distal opening (42) of the receptacle (420R) are located in close proximity to one another, which radial offset is greater than a length of the annular recess (31) formed by the device attachment feature (310).
(FR) La présente invention concerne un outil (600) pouvant fonctionner avec un cathéter (400) dans un système d’intervention médicale qui récupère un dispositif médical (300) d’un site d’implant, le dispositif (300) comprenant un élément de fixation (310) qui forme un renfoncement annulaire (31) à venir en prise avec un lasso (620) de l’outil (600) destiné à attraper le dispositif (300), et une paroi latérale la plus distale (420) du cathéter (400) qui définit un réceptacle (420R) dans lequel le dispositif attrapé (300) est récupéré. Un guide (610) de l’outil (600) comprend une paroi latérale (610S) définissant une lumière (601) dans laquelle le lasso (620) s’étend pour le déploiement à l’extérieur depuis une ouverture distale (62), pour attraper et récupérer le dispositif implanté (300). La paroi latérale (230, 420, 61, 710S) établit un décalage radial entre l’ouverture distale guide de la lumière (62) et la paroi latérale la plus distale (610S) du cathéter (400), lorsque l’ouverture distale guide de la lumière (62) et une ouverture distale (42) du réceptacle (420R) sont situées en étroite proximité l’une de l’autre, lequel décalage radial est supérieur à une longueur du renfoncement annulaire (31) formé par l’élément de fixation du dispositif (310).
