Abstract
An apparatus includes a shaft and an inflatable sleeve catheter. The shaft is configured for insertion through a sheath into a cavity of an organ of a patient. The inflatable sleeve catheter is fixed to a distal end of the shaft, with the inflatable sleeve catheter including (i) a resilient inner end section, which is fixed to the distal end of the shaft and is formed so as to assume a predefined shape when unconstrained, (ii) an inflatable sleeve that envelopes the inner end section, and a plurality of electrodes that are disposed over the inflatable sleeve and are configured to contact tissue.
Claims20
A method, comprising:
- inserting into a cavity of an organ of a patient, through a sheath, an inflatable sleeve catheter fixed to a distal end of a shaft, the inflatable sleeve catheter comprising:
- a resilient inner end section, which is fixed to the distal end of the shaft and is formed so as to assume a predefined shape when unconstrained;
- an inflatable sleeve that envelopes the resilient inner end section;
- and
- a plurality of electrodes that are disposed over the inflatable sleeve and are configured to contact tissue;
- after the inflatable sleeve catheter exits the sheath in the cavity and the resilient inner end section assumes the predefined shape, inflating the inflatable sleeve;
- making contact between the plurality of electrodes and tissue;
- and
- performing a medical procedure using the electrodes.
A method of manufacturing an inflatable sleeve catheter, the method comprising:
- fixing to a distal end of a shaft a resilient inner end section, which is formed so as to assume, when unconstrained, a predefined shape;
- enveloping the resilient inner end section with an inflatable sleeve;
- and
- disposing over an outer circumference of the inflatable sleeve a plurality of electrodes that are configured to contact tissue.
