Abstract
A medical apparatus includes a shaft and a basket assembly. The shaft is configured for insertion into a cavity of an organ of a patient. The basket assembly is connected distally to the shaft and includes electrodes, which are configured to apply electrical energy to tissue within the cavity. The basket assembly further includes a flexible porous sheath, which is fitted over the basket assembly and is configured to contact the tissue within the cavity while simultaneously (i) preventing the electrodes from indenting the tissue and (ii) allowing electrical energy applied from the electrodes to be delivered to the tissue.
Claims18
A medical apparatus, comprising:
- a shaft configured for insertion into a cavity of an organ of a patient;
- a basket assembly connected distally to the shaft and comprising electrodes, which are configured to apply electrical energy to tissue within the cavity;
- and a flexible porous sheath, which is fitted over the basket assembly and is configured to contact the tissue within the cavity while simultaneously (i) preventing the electrodes from indenting the tissue and (ii) allowing electrical energy applied from the electrodes to be delivered to the tissue, the flexible porous sheath comprising a minimal given thickness that is configured to provide cushioning to prevent the electrodes from indenting the tissue.
A medical method, comprising:
- inserting a basket assembly connected distally to a shaft into a cavity of an organ of a patient;
- applying electrical energy to tissue within the cavity using electrodes comprised in the basket assembly;
- and contacting the tissue within the cavity using a flexible porous sheath, which is fitted over the basket assembly and is configured to simultaneously (i) prevent the electrodes from indenting the tissue and (ii) allow electrical energy applied from the electrodes to be delivered to the tissue, the flexible porous sheath comprising a minimal given thickness that is configured to provide cushioning to prevent the electrodes from indenting the tissue.
A method for producing a medical probe, the method comprising:
- producing a basket assembly, comprising:
- electrodes, which are configured to apply electrical energy to tissue within a cavity;
- and a flexible porous sheath, which is fitted over the basket assembly and is configured to contact the tissue within the cavity while simultaneously (i) preventing the electrodes from indenting the tissue and (ii) allowing electrical energy applied from the electrodes to be delivered to the tissue, and connecting the basket assembly to a shaft configured for insertion into the cavity of an organ of a patient, the flexible porous sheath comprising a minimal thickness that is configured to provide cushioning to prevent the electrodes from indenting the tissue.
