Publication number: 20240076599Abstract: An electroporation apparatus has an electroporation probe terminals for linking with electrodes. A foam is injected at the treatment site to displace blood rather than mixing with it, increasing the contact time of a higher concentration of active agent with the tissue and thus resulting in greater efficacy. With foam solutions, a lower concentration of agent can be used to obtain the same therapeutic effect as in their liquid counterpart, reducing the prevalence of side effects associated with higher concentrations. A foam solution compared to an equivalent liquid solution enables more efficient cell electroporation particularly where bipolar pulses have been employed by mitigating an increase in tissue conductivity as would normally be observed with a comparable liquid solution. A more efficient cell permeabilisation would result in better results where electroporation is being delivered alone or as a tool to aid in the uptake of molecules into the cell.Type: ApplicationFiled: October 18, 2023Publication date: March 7, 2024Applicant: MIRAI MEDICAL LIMITEDInventors: Declan SODEN, Colin FORDE, Sean KINSELLA, Tony MOORE

Patent number: 8795329Abstract: The present invention provides systems and methods for occluding or closing a patent foramen ovale of a patient (PFO). The invention includes a catheter carrying an energy delivery element. The catheter introduces the energy delivery element into the patent foramen ovale of a patient's heart. Once appropriately positioned, the energy delivery element applies energy, such as radiofrequency energy, to the tissues surrounding the patent foramen ovale. The application of energy causes the tissues to join together, occluding the patent foramen ovale. The energy delivery element may be removable or permanently implanted in the patent foramen ovale.Type: GrantFiled: August 15, 2010Date of Patent: August 5, 2014Assignee: W.L. Gore & Associates, Inc.Inventors: Sean Forde, James Scutti, David J. Callaghan, Erik Glaser, Carol A. Devellian, Steve W Opolski

Patent number: 7232421Abstract: The present invention provides a system for delivering a therapeutic agent into tissue in combination with an implant device (2). Preferably the therapeutic substance is contained within a pellet form (14) that is deliverable into the interior of the device (2) after it has been implanted. In a preferred embodiment the implant device (2) comprises a flexible coiled spring body, the coils (4) of which have the proper diameter and spacing to contain the pellet (14) within the interior of the device (2) to contact the therapeutic agent. In treatment of ischemic tissue such as that of the myocardium of the heart, the mechanical irritation of the tissue caused by the implanted device (2) can help to provide an angiogenic effect. Additionally, the cavity (18) provided by the interior of the device (2) permits blood to pool around the pellet (14) and mix with the therapeutic agent. Several delivery systems have provided for delivering the implant and pellet (14) sequentially or simultaneously.Type: GrantFiled: May 12, 2000Date of Patent: June 19, 2007Assignee: C. R.
