Abstract

A connector for connecting an implant device to tissue of a person's body. The connector including a frame having first and second arms. The first and second arms define an opening, where at least a portion of the implant device is inserted through the opening. After insertion, an additional securing member is connected to the frame. The securing member is adapted to receive at least one suture to secure the frame to the tissue. The connector includes an adjuster that is movably connected to the first and second arms, where the adjuster is operable to cause the first and second arms to move toward each other and engage the implant device.

First claim

The invention is claimed as follows:

1. A connector for connecting a heart pump to a cardiovascular system of a person's body, the cardiovascular system including a heart, the connector comprising:
a frame including a first arm and a second, the first and second arms defining a channel therebetween and a first opening configured to receive at least a portion of a heart pump inserted through the opening into communication with a cardiovascular system;
a positioner movably connected to the frame, the positioner defining a second opening that is coaxial with the first opening, at least a portion of the heart pump configured to be located in the first and second openings with the positioner between the frame and the heart pump, the positioner is rotatable and slidable relative to the frame to adjust the position of the heart pump relative to the frame;
a securing member connected to the frame, the securing member adapted to receive at least one suture to secure the frame to a tissue of a heart; and
an adjuster movably connected to the first and second arms, the adjuster is operable to cause the first and second arms to move toward each other and engage the heart pump,
the securing member forming a tight seal around the heart pump and is adapted to move the heart pump relative to the frame with the first and second arms in engagement with the heart pump.

2. The connector of claim 1 , wherein the connector includes an additional securing member positioned between the securing member and the frame.

3. The connector of claim 2 , wherein the securing member includes a lip substantially covering the additional securing member.

4. The connector of claim 2 , wherein at least one of the securing members includes one of a felt and a polyester.

5. The connector of claim 1 , further comprising a sealer removably connected to the frame.

6. The connector of claim 5 , wherein the sealer includes an o-ring.

7. The connector of claim 1 , wherein the adjuster is a screw which is threadingly engaged with at least one of the first and second arms.

8. The connector of claim 1 , further comprising a pin frictionally connected to one of the first and second arms to substantially minimize lateral movement of the adjuster.

9. The connector of claim 1 , wherein the frame defines at least one opening sized to accept at least one suture for securing the frame to the securing member.

10. The connector of claim 1 , wherein the frame defines a plurality of openings, each of the plurality of openings sized to accept at least one suture for securing the frame to the securing member.

11. The connector of claim 1 , wherein the positioner is made with a pliable material.

12. The connector of claim 1 , wherein the heart pump includes a shaft positioned through the positioner.

13. A connector for connecting an implant device to a cardiovascular system of a person's body, the cardiovascular system including a heart, the connector comprising:
a frame including a first arm and a second, the first and second arms defining a channel therebetween and a frame opening, at least a portion of an implant device, including a heart pump, configured to be inserted through the frame opening into communication with a cardiovascular system;
a positioner movably connected to the frame, the positioner defining a proximal opening and a distal opening, the proximal opening and the distal opening including a first position coaxial with the frame opening and a second position offset to the frame opening, at least a portion of the heart pump configured to be located in the frame opening and the proximal and distal openings with the positioner between the frame and the implant device, and the positioner movable to adjust the position of the implant device relative to the frame;
a securing member connected to the frame and adapted to secure the frame to a tissue of a heart; and
an adjuster movably connected to the first and second arms, the adjuster operable to cause the first and second arms to move toward each other and engage the implant device,
the positioner forming a tight seal around the implant device and movable between at least the first and second positions with the first and second arms in engagement with the implant device.

14. The connector of claim 13 , wherein the positioner is rotatable and slideable relative to the frame.

15. The connector of claim 13 , wherein a movement of the positioner from the first position to the second position moves the implant device from the first position to the second position.

16. The connector of claim 13 , wherein the positioner is made of a pliable material.
