Suture-free clamp and sealing port and methods of use
First Claim
1. A clamp for introduction of a medical device, comprising:
- a housing having an outer surface, a proximal end, a distal end, and a lumen therebetween, the lumen adapted to receive a medical device for introduction through body tissues; and
a collar that releasably engages the proximal end of the housing, the collar having a central opening aligned with the lumen of the housing for passage of the medical device, and a surface operable to clamp tissue between the collar and the housing.

Abstract
A suture-free clamp for sealing body tissue during introduction of medical devices, such as a cannula, aspirator, stent, endoscope, and pressure monitor. The clamp may be used in a patient'"'"'s vascular tissues, such as the right atrium and the aorta. The clamp comprises a generally cone-shaped housing which includes a lumen for receiving a medical device, and a collar having a central opening for passage of a medical device, the collar connected to a proximal end of the housing by a plurality of struts. The proximal end of the housing and the collar each has an annular surface. The two surfaces are opposed, and are operable to clamp tissue therebetween, and to thereafter release the tissue by releasing the clamp. Methods are also disclosed for using the suture-free clamp for sealing body tissues during introduction of a medical device.

12. A method for introduction of a medical device, comprising the steps of:
-
providing a clamp comprising a housing having a proximal end, a distal end, and a lumen therebetween, the clamp further comprising a collar that is connectable to the proximal end of the housing, the collar having a central opening aligned with the lumen of the housing;
making an incision in the tissue;
introducing the distal end of the housing through the incision;
operating the collar to engage tissue between the collar and the housing; and
introducing a medical device through the lumen of the housing into the body. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
