20100286485 | Adaptable tissue retractor with plurality of movable blades - An adjustable multi-bladed tissue retractor capable of producing an incrementally variable or fine-tunable retracted opening in a surgical incision, or a body cavity. The adjustable tissue retractor comprises an actuator coupled to a retractor housing and a movable linkage arrangement capable of moving the plurality of tissue-engaging blades attached thereto, between a closed-blade configuration and an open-blade configuration. Through the application of a predetermined input to the actuator, a controlled, or selectable spaced apart spatial relationship of the plurality of tissue retracting blades results, and whereby, in use, the tissue retractor may be customized, or individually tailored to suit the specific anatomy of the patient. | 11-11-2010 |
20110046448 | Cardiac tissue retractor with associated valve cusp depressor - A tissue retracting apparatus for use in cardiac surgery having a first tissue retracting member configured and sized to retract a cardiac tissue of the patient's heart in a manner to obtain surgical access to a target heart valve located within an internal heart cavity, and a second tissue retracting member configured and sized to retract, depress or displace a valve cusp tissue of the target heart valve in a manner to obtain surgical access beyond the target heart valve. In use, the second tissue retracting member is operatively couplable to the first retracting member, so that the first and second retracting members cooperate together to collectively allow the simultaneous retraction of both (i) a cardiac tissue of the patient's heart, and (ii) a valve cusp of the target valve while a surgical intervention can be carried out on either the target heart valve or a subvalvular structure of said target heart valve. | 02-24-2011 |
20110144450 | Tissue retractor with movable blades and articulating wrist joint - A surgical retractor for retracting a body tissue comprising a plurality of cooperating tissue-retracting blades connected to a retractor housing through a linkage arrangement. The tissue-retracting blades are movable between a closed-blade configuration wherein said blades are in proximity to one another and an open-blade configuration wherein said blades are in a spaced apart spatial relationship. The blade spatial relationship being variably selectable by the degree of actuation input applied to a first actuator that is coupled to both the retractor housing and the linkage arrangement. The tissue-retracting blades are also movable, together as a blade assembly in a selected blade spatial relationship, when a second actuation input is applied to a second actuator to articulate a pivoting wrist joint configured in the retractor housing. Actuating the wrist joint through the second actuator allows the surgeon to vary the orientation of the spaced apart blades relative to the housing through an angular displacement of the blades about a wrist pivot axis. | 06-16-2011 |

20100217092 | Surgical tool for measurement of valve annulus and cusp geometry - A surgical tool for visually assessing or measuring the aortic structures contained within a generally tubular aortic root. The surgical tool is appropriately configured and sized to be insertable within an aortic root during surgery. The surgical tool comprises a handle portion and a cylindrical portion connectable thereto. The cylindrical portion defines an external cylindrical surface and extends in height along a tool axis between a base portion and a top portion. The cylindrical portion being optically clear or having at least a section thereof that is sufficiently transparent whereby, in use, when the surgical tool is placed within the aortic root and the aortic structures are in contact with the external cylindrical surface, the aortic structures are visible through said optically clear or sufficiently transparent section. The cylindrical portion preferably further comprises an array of reference datum and measurement increments visible through the optically clear section such that the visualization and measurement of the aortic structures may be effected with reference to the array. | 08-26-2010 |
20110144438 | SURGICAL APPARATUS AND METHOD FOR PERFORMING TRANSABDOMINAL CARDIAC SURGERY - The invention provides a surgical apparatus and method for performing less-invasive, closed chest cardiac surgery through a transabdominal approach, without cardiopulmonary bypass. In a preferred embodiment, the invention provides a heart manipulator and a coronary stabilizer which are deployed through an access cannula and secured relative to a stationary support through a surgical arm. Heart manipulator and coronary stabilizer cooperate together to enable access to all the coronary artery territories of the heart through a single access cannula. Also provided is a diaphragm tissue retractor. | 06-16-2011 |
20110270283 | SUTURE RETENTION DEVICE - A tissue retractor for displacing body tissue during surgery includes a tissue piercing member such as a surgical needle, a wire-like filament such as a suture line affixed to the surgical needle, a fixed element such as an anchoring port being associated with a stable surgical platform such as a sternum retractor and a movable element such as an anchoring plug cooperating with anchoring port to engage a portion of suture line after the suture line is threaded through the body tissue with the surgical needle and after the suture wire is tensioned to effect a predetermined displacement of the body tissue. The predetermined displacement of body tissue is maintained by retention of the engaged portion of suture line by the fixed anchoring port and the movable anchoring plug. | 11-03-2011 |
20120010701 | AORTIC ANNULOPLASTY RING - An annuloplasty ring to resize a dilated aortic root during valve sparing surgery includes a scalloped space frame having three trough sections connected to define three crest sections. The annuloplasty ring is mounted outside the aortic root, and extends in height between a base plane and a spaced apart commissure plane of the aortic root. At least two adjacent trough sections are coupled by an annulus-restraining member or tether that limits the maximum deflection of the base of the annuloplasty ring. In use, the tether is preferably located in proximity to the base plane of the aortic root. The annuloplasty ring is movable between a first, substantially conical configuration occurring during a diastolic phase of the cardiac cycle, and a second, substantially cylindrical configuration occurring during a systolic phase of the cardiac cycle. | 01-12-2012 |

20130073033 | EXPANDABLE ANNULOPLASTY RING AND ASSOCIATED RING HOLDER - Devices and methods are provided for surgical repair of dilated aortic root to restore aortic valve competence while preserving native leaflets. In one aspect of the invention an expandable annuloplasty ring is provided for external placement at the base of a dilated aortic root. The expandable ring is capable of elastically expanding between a first diastolic diameter and a larger second systolic diameter to provide a physiologically representative surgical repair of the aortic root. In a further aspect of the invention, is provided a holder assembly for aortic annuloplasty ring and suitable for other cardiac valve prosthesis. The holder assembly consists of a holder body pivotingly coupled to a handle member through a ball-and-socket arrangement. | 03-21-2013 |
