A valve sizer having a movable element mounted to the distal end of a shaft. A valve sizing portion includes the movable element so that the valve sizing portion may be adjusted to correspond to a number of different available replacement valve sizes. An indicator mounted to the proximal end of the shaft indicates the valve size corresponding to the outer dimension of the valve sizing portion.

Valve sizer

Valve sizer and method of use

The invention provides devices and methods for suture placement while performing less invasive surgical procedures within a body cavity. In an exemplary embodiment, the invention provides for the placement of sutures within the heart or a great vessel that is accessed from outside the closed chest. According to one exemplary method, the patient's heart valve is accessed through an intercostal port in the patient's chest. At least one needle having a suture is then directed into the annulus while visualizing through the port placement of the needle into the annulus. The needle is then passed through the annulus.

Endoscopic suturing devices and methods

The invention provides a system and method for manipulating a tissue structure within a body cavity. In a preferred embodiment, the invention provides a system and method for retracting and supporting the heart wall to provide access into the heart during a cardiac surgical procedure. The system comprises a tissue supporting member (500) positionable through a first percutaneous intercostal penetration into the thoracic cavity. The tissue supporting member has a contact surface (502) configured for supporting a portion of the heart wall. A retractor (40a) includes a shaft (400) with a proximal end, a distal end configured for introduction through a second percutaneous penetration and a diameter less than the width and length of the contact surface. A hook (428) is slidably coupled to the distal end of the shaft for releasably holding the tissue supporting member such that the contact surface is arranged transversely to the longitudinal axis of the shaft. With this configuration, the shaft and tissue supporting member can be introduced through two separate percutaneous penetrations and connected together within the thoracic cavity for retraction of the heart wall.

A powered rotatable surgical tissue working tool for chucking in a powered rotating surgical handpiece includes a tubular elongate outer member having a distal tip portion angled off the central axis of the proximal portion of such tubular outer member, by reason of a angled portion therebetween. A rotatable elongate inner member extends coaxially and rotatably within the tubular outer member and has a rotatably drivable proximal portion, a distal tip portion for tissue working interaction with the distal tip portion of the outer member, and a flexibly bendable portion therebetween rotatably housed within the angled portion of the outer member. An annular space between the inner and outer member communicates between the distal tip portions thereof and the handpiece for permitting suction withdraw of flowable materials from a surgical site axially through such annular space and to a suction source. The annular space is maintained between the flexible portion of the inner member and the angled portion of the outer member despite rotation of the inner member.
