Abstract

A valve insertion unit for holding a heart valve or like prosthetic device to be inserted within the body, for engaging and spreading an expansible valve-receiving ring previously implanted in the body, for moving the valve into position within the ring, releasing the ring over the valve and releasing the valve from the holder. The valve holder is normally biased opened, fingers are used to spread the ring and are biased to a normally closely spaced-apart position, and movement of the holder along the fingers while portions of the holder engage the fingers expands the ring. When the holder, in an extreme axial position of travel, leaves the ends of the fingers, the ring automatically snaps into position to hold the valve in place within the body and the valve holder releases it grip on the valve so the entire instrument may be removed from the body.

SURGICAL INSTRUMENT FOR IMPLANTING A PROSTHETIC HEART VALVE OR THE LIKE BACKGROUND OF THE INVENTION The present invention is directed generally to surgical instruments, and more particularly to a surgical instrument or tool adapted to facilitate insertion of a prosthetic device such as a replacement heart valve or the like into position within a person or animal in a simple, rapid and accurate manner. More particularly, in one embodiment, the invention is directed to a tool for use during surgery to insert an atrio-ventricular into the annulus fibrosis of the heart of a person.

Recently, as extensive and complex surgery becomes more common, many attempts have been made to insure that a person or animal being surgically operated upon undergoes the least exposure to damage which is consistent with performing the steps necessary to an operation. For example, as open heart surgery has become more common, there has been a need not only for improved surgical techniques and prosthetic devices to bring about the results desired, such as methods of implanting improved synthetic heart valves and the like, but also a need for means of assuring that the surgical patient is exposed to potentially dangerous and damaging conditions for the least possible time.

Thus, although it is now somewhat common to replace a damaged heart valve, such as the atrio-ventricular heart valve, this surgery requires that the heart be open and the blood of the patient be circulated by artificial means. Artificial blood circulation pumps, although satisfactory in general sense, are known by those skilled in medicine to cause some measurable damage to the blood of the patient, and therefore increase the likelihood that the patient will suffer either immediate or eventual adverse affects from such exposure.

Therefore, there has been a need for minimizing the time during which the heart of a patient must remain open during surgery, and attempts to satisfy this need have included the provision of heart valves having improved means for implantation thereof. For example, copending application Ser. No. 721,360 filed Apr. 15, 1968, discloses a heart valve which is held in place by a resilient snapring sewn into the annulus fibrosis of a patient before the valve is inserted, and which then supports the valve in position within the heart. This construction has significantly simplified the suturing techniques heretofore, used, and as a result, has decreased the time during which the heart must remain open during surgery. This construction eliminates the time consuming formerly used method of suturing the valve in place by a sewing cuff attached thereto. The present invention is directed to providing an instrument for spreading or stretching such a snapring to facilitate insertion of a heart valve in place within the patient, and thereby to reduce even further the time during which the patients heart must remain open during surgery.

Accordingly, an object of the present invention is to provide a surgical instrument which is particularly useful in heart surgery.

Another object is to provide a surgical instrument adapted to grip a prosthetic device to support it during positioning, and to release it in a desired position within the body.

Another object is to provide a surgical tool which is adapted to engage and spread apart a snapring or the like to facilitate insertion therein of a prosthetic device and to release the device in a position to be engaged by the snapring when the ring is released from a spread apart position.

A further object of the invention is to provide a device which includes means thereon for engaging a snapring disposed within a portion of a patient, and which is remotely operable to spread said ring apart, and to move a valve held therein to a position of engagement while simultaneously expanding the portions of the tool'engaged with the ring and holding together the valve receiving or supporting element until a position of engagement between the valve and the ring is reached.

In general, these objects are achieved by providing an instrument comprising a valve holder element supported on resilient fingers from a frame, ring spreading fingers attached to a second frame unit, and means for providing engagement and release between the spreading fingers and the holder so that moving the valve into position spreads the ring for valve reception, and further movement allows the ring to engage the valve just as the holder releases the valve so the instrument may be withdrawn from the patient.

The exact manner in which this invention achieves its objects will become more clearly apparent when reference is made to the following detailed description of the preferred embodiments of the invention, to the appended claims, and to the accompanying drawings, in which like reference numerals indicate corresponding parts throughout.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION Although the surgical tool of the present invention is useful with a number of different prosthetic devices and the like, the invention will be described in reference to a preferred embodiment in which a heart valve, for example, an atrio-ventricular heart valve of the Edwards type, is held therein and disposed within an expansible snapring previously sewn in position in the annulus fibrosis of a human or animal heart.

Referring now in particular to FIG. I, the surgical tool is shown to comprise means for engaging and spreading an expansible ring in the form of a ring spreader assembly 12 and means for receiving a synthetic heart valve in the form of a valve holder assembly 14. The ring spreader assembly ll2 includes a generally ring-shaped frame unit 16, and a plurality of means in the form of rods or fingers 18 for engaging and spreading apart an expansible snapring 20, such as a silicone rubber or stainless steel snapring. The remote ends 22 of the fingers l8 engage the ring 20 while the proximate ends 24 of the fingers 18 are fixedly attached to the frame 16. A valve 26 is removably held between an upper semicircular collar 28 and a lower circular collar 30, which combine to form valvereceiving means in the form of a holder 32. Preferably, the collars 28, 30 are biased apart by a pair of valve holder rods 34 which terminate at the proximate ends 36 thereof in an annular ring 38 which serves as a frame for the valve holder 32.

An alignment ring 40 having a plurality of openings 42 therein, may be disposed between the frame 16 and the holder 32 for receiving the fingers 18, in a manner and for purposes which will be described in further detail herein.

Referring now to FIGS. 2 and 3, it can be seen that the ends 22 of the fingers 18 are normally biased to a closely spacedapart position by the inherent resiliency of the fingers 18, but that the ends 22 thereof may be urged to a spaced-apart position such as that shown in FIG. 2 by moving the upper and lower semicircular collars 28, 30 which comprise the holder 32 axially of the fingers 18. This is accomplished because the openings 42 in the collars 28, 30 receive the fingers l8 and act as means for spreading them apart upon axial holder movement which occurs when the frame 38 of the valve holder assembly 14 is moved axially of the instrument 10 toward the ends-22 of the fingers 18.

In FIG. 3, it is shown that, when the entire holder assembly 14 is moved to a sufficient axial extent, such as to the extreme right hand position shown in FIG. 3, the collars 28, 30 move free of the rod ends 22, thereby enabling the resilient, outwardly biased rods 34 to move the collars 28, 30 radially apart, and the ends 22 of the fingers 18 to return to a closely spaced-apart position.

Referring now to FIGS. 4 and 5, a silicone rubber ring 20 is shown as being sewn in place within the annulus fibrosis 44 of the atrio-ventricular heart wall 46 by a plurality of sutures 48. The interior of the ring 20 is engaged by the remote ends 22 of the fingers 18, and this serves to spread the expansible ring 20 apart a preset distance as the collars 28, 30 are moved toward the axially remote ends 22 of the fingers 18. As shown in FIG. 4, the valve 26 includes a nose portion 50, partially defined by a plurality of supporting members 52 which also serve to cage a ball 54, which is the operational portion of the valve 26. Around the exterior of the valve seat 56 is a ring-retaining groove 58, partially defined by a shoulder portion 60 which is adapted to engage the ring 20 to insure proper registry of the ring 20 in the groove 58. A land 62 in the holder 32 releasably engages a second shoulder 64 on the valve 26. Thus, the land 62 on the collars 28, 30 engages the valve 26 and holds it in position as long as the collars 28, 30 are held closed by engagement between the openings 42 therein and the fingers 18.

FIG. shows that, in operation of the device, as the extreme axial movement limit of the collars 28, 30 is reached, the shoulder portion 60 of the valve has engaged the ring 20 so that it is in a position of registry with the groove 58 and the ring 20 cannot move past the desired position. As the ends 22 of the fingers 18 undergo relative movement with respect to the holder 32, and are withdrawn into the openings 42, the ends 22 no longer engage the ring which snaps into the groove 58 to support the valve 26 in a desired position within the heart. Slight further movement of the collars 28, 30 with respect to the rod ends 22 allows the collars 28, 30 to release the valve, and the entire unit is then withdrawn.

When it is desired to repeat the operating cycle for another operation, a valve is placed between the collars 28, 30, the collars are then closed, and the alignment ring 40 is moved towards the remote ends 22 of the fingers 18, thereby spacing the ends 22 apart a distance equal to their spacing when engaged with the openings 42. This allows the collars 28, 30 to be placed over the fingers 18 in a simple operation and enables the entire valve holder assembly, including a valve 26 held therein, to be moved to the left as shown in the drawings. This permits the ends 22 of the rods or fingers 18 to return to their closely spaced-apart position for entry into the center of the ring. This action is illustrated in FIG. 7, which shows a valve 26 held in the collars 28, 30, the frame 38 moved to an extreme left-hand position, and the ends 22 of the fingers l8 closely spaced apart.

In use, when the heart wall or membrane is open, the flexible rubber or expansible steel snapring 20 is rapidly sewn directly into place within the annulus fibrosis in the place from which the natural atria-ventricular valve has been removed. Since the ring 20 and the valve 26 to be inserted therein are separate pieces, the valve does not interfere with the sewing operation. Immediately after the ring is located and sewn in the desired position, the ends 22 of the rods or fingers 18 are placed within the snapring 20 and the ring 38 is manipulated so as to move the valve into position within the split ring 32 and subsequently released therefrom in one operation, while the ring 20 is in registry with the groove 58. The surgical instrument of the present invention thus makes it possible to simplify heart surgery and greatly reduce the time required for implantation of a valve within the heart, thereby reducing the time during which the heart must remain open and during which the blood of the patient is being circulated by artificial means.

In a preferred embodiment, the unit is made of a stainless steel construction for corrosion resistance, and ease of sterilization even though the construction is such that other materials may be used, particularly if a lower cost disposable unit is desired to be made.
