Abstract
An introducer sheath for use in hybrid procedures on the heart includes a shaft having a distal balloon which is inflated inside the heart wall. A proximal collar is slidable along the shaft and locked to anchor the sheath to the wall of the heart. The sheath has markings visible to both the naked eye and under fluoroscopy to aid in judging the depth of insertion.

1-37. (canceled)
An introducer sheath comprising:
- a tubular shaft having a proximal end and a distal end;
- a balloon adjacent to the distal end of the shaft;
- and
- a proximal anchoring element having a release configuration in which the anchoring element is movable along the shaft and an anchoring configuration in which a tissue bridging gap between the anchoring element and the balloon is reduced and the anchoring element is locked to the shaft.
1 more element
A hybrid method for accessing a heart comprising the steps of:
- providing an introducer sheath having a shaft and a balloon at the distal end of the shaft;
- making an opening to provide an access point into the heart;
- with the balloon in a deflated configuration, inserting a distal portion of the introducer sheath through the incision;
- inflating the balloon to provide a safety bumper at the distal end of the sheath;
- and
- carrying out a procedure by passing devices through the sheath.
