AN ELECTROPORATION APPARATUS AND METHOD
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 permeabilization 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.
Conductive Member For Use In Radiofrequency Ablation
A conductive member such as conductive pad (1) for use in radiofrequency ablation, the conductive member being flexible so as to conform to a subject's skin, the conductive member comprising a conductive skin contact layer (5) arranged for contact with the subject's skin and a conductive layer (4) over the conductive skin contact layer, in which the conductive skin contact layer (5) and the conductive layer (4) are both conductive to DC electrical signals.
Adjustable end effector structure for tissue ablation
An adjustable, structure providing an ablation apparatus, having a preformed structure made from compliant material such as rubber like material, foam or gel, with particles made of electromagnetic energy absorbing material. An antenna for radiating emitted microwave energy to generate heat and thus cause cavity ablation is located inside of the conformable adjustable structure. When end effector portion is inserted into the body cavity, the compliant adjustable structure is compliant to conform to a profile of the cavity to be ablated, and microwave energy is received to heat the adjustable structure resulting in heat energy that will ablate the cavity tissue in contact with the compliant end effector. Additionally, the shape of the end-effector compliant structure can be differently formed, depending of shape of tissue cavity to be ablated.
Electrosurgical instrument having multiple treatment modalities
An electrosurgical instrument which is capable of selective operation in any of (i) a plasma-generating mode for surface coagulation, (ii) a non-ionising radiation mode for deeper coagulation, e.g. using microwave energy, and (iii) a liquid administration mode for conveying liquid to a treatment site, e.g. to constrict a bleeding vessel so that a clinician can get control of the bleed. These operating modes may be provided in an electrosurgical instrument that is physically configured to be suitable for applying pressure to a tissue vessel, e.g. to act as a tamponade to stem bleeding.
