Publication number: 20240066219Abstract: A fluid management and medical device system may include a fluid management system and a medical device having one or more sensors proximate the distal end of the elongate shaft of the medical device. The controller of the fluid management system may be configured to calculate a fluid deficit when the distal end of the elongate shaft is disposed within a patient and configured to automatically pause fluid deficit calculation when the distal end of the elongate shaft is removed from the patient. In some instances the controller is configured to calculate the fluid deficit using rotational speed of the inflow pump in combination with a difference between a change in weight of a fluid supply source supplying fluid to the fluid management system and a change in weight of a collection container collecting fluid from the fluid management system.Type: ApplicationFiled: November 8, 2023Publication date: February 29, 2024Applicant: BOSTON SCIENTIFIC LIMITEDInventors: PAUL BYRNE, LEE SMITH, LEAH FANNING, NIRAJ PRASAD RAUNIYAR, NISHANT KHATTAR, VIVEK SHAH, DIPEN ARUN TASGAONKAR

Patent number: 10111607Abstract: A method and apparatus that utilizes a force-time integral for real time estimation of lesion size in catheter-based ablation systems. The apparatus measures the force exerted by a contact ablation probe on a target tissue and integrates the force over an energization time of the ablation probe. The force-time integral can be calculated and utilized to provide an estimated lesion size (depth, volume and/or area) in real time. The force-time integral may also account for variations in the power delivered to the target tissue in real time to provide an improved estimation of the lesion size. In one embodiment, the force metric can be used as feedback to establish a desired power level delivered to the probe to prevent steam popping.Type: GrantFiled: December 22, 2015Date of Patent: October 30, 2018Assignee: ST JUDE MEDICAL INTERNATIONAL HOLDING S.À R.L.Inventors: Giovanni Leo, Dipen Shah, Hendrik Lambert

Publication number: 20170007323Abstract: A method and apparatus that utilizes a force-time integral for real time estimation of steam pop in catheter-based ablation systems. The apparatus measures the force exerted by a contact ablation probe on a target tissue and an energization parameter delivered to the ablation probe. The exerted force and energization parameter can be utilized to provide an estimation of the probability of steam pop. In one embodiment, the force and energization metrics can be used as feedback to establish a desired contact force and energization level combination to prevent steam popping.Type: ApplicationFiled: July 14, 2016Publication date: January 12, 2017Inventors: Giovanni Leo, Dipen Shah, Hendrik Lambert
