Abstract
According to one embodiment, a protective device for use in congestive heart failure treatments, and other treatments, includes a control mechanism, an elongate shaft, and a protective plate. The control mechanism is coupled with a proximal end of the elongate shaft and the protective plate is pivotably coupled with a distal end of the elongate shaft. The elongate shaft enables the protective plate to be inserted within a body and navigated distally of a heart wall. The protective plate has a relatively wide and thin body portion and is pivotable relative to the elongate shaft by operation of the control mechanism. Pivoting and/or navigating of the protective plate within the body allows the protective plate to be positioned adjacent the heart wall to shield body organs or tissue surrounding the heart wall from being damaged by surgical instruments inserted through the heart wall.
Core Innovation
The invention describes tissue/organ protecting devices and associated methods for treating congestive heart failure. A protective plate of a protective device is inserted within an incision of a body and is pivotably coupled with a distal end of an elongate shaft of the protective device. The protective plate is advanced within the body and positioned adjacent a rear wall of a heart, or adjacent a heart wall of a ventricle.
A control mechanism is operated to pivot the protective plate relative to the elongate shaft to position the protective plate adjacent the rear wall of the heart. With the protective plate positioned between a surgical needle or surgical instrument and body organs or tissue surrounding the rear wall, the protective plate shields the body organs or tissue from being damaged. The method also includes inserting an anchor through the rear wall of the heart, where the anchor is coupled at a distal end of a tension member extending through the rear wall.
The method tensions the tension member to engage the anchor with the rear wall and urge the rear wall toward another wall of the heart. In some embodiments, the protective plate may be positioned behind a right ventricle, and pivoting and locking of the protective element in a second position are described. The protective element shields body organs or tissue adjacent the heart wall from a surgical instrument inserted through a septum and into the ventricle.
Claims Coverage
The document includes two independent claims. Across these independent claims, four main inventive features are emphasized.
Pivotably coupled protective plate inserted and positioned adjacent a rear wall
A method for treating congestive heart failure comprising inserting a protective plate within an incision, where the protective plate is pivotably coupled with a distal end of an elongate shaft, advancing the protective plate within the body to position it distally of a rear wall of a heart, and positioning the protective plate adjacent the rear wall of the heart.
Control mechanism pivots the protective plate to shield organs during needle insertion
Operating a control mechanism to pivot the protective plate relative to the elongate shaft to position the protective plate adjacent the rear wall, inserting a needle through the rear wall with the protective plate positioned between the needle and body organs or tissue surrounding the rear wall to shield the body organs or tissue from being damaged by the needle.
Anchor insertion and tensioning to urge the rear wall toward another wall
Inserting an anchor through the rear wall of the heart, the anchor coupled at a distal end of a tension member extending through the rear wall, and tensioning the tension member to engage the anchor with the rear wall and urge the rear wall toward another wall of the heart.
Protective element shielding during surgical instrument insertion into a ventricle
A method for protecting body organs or tissue during a surgical procedure comprising inserting a protective element within an incision, advancing the protective element toward a heart wall of a ventricle of a heart, positioning the protective element adjacent the heart wall of the ventricle, inserting a surgical instrument through a septum and into the ventricle, and using the protective element positioned adjacent the heart wall to shield body organs or tissue adjacent the heart wall from the surgical instrument.
Independent claim coverage spans protective plate or protective element positioning adjacent a heart wall to shield organs during insertion of a needle or surgical instrument, and anchor insertion and tensioning to urge a rear wall toward another wall.
