An introducer system having an elongate shaft with proximal and distal ends. A flexible sleeve is mounted on the distal end of the shaft and is adapted to circumferentially cover the outer surface of a distal end of a cannula when the shaft is positioned within a lumen of the cannula. The introducer system has dilation capabilities which facilitates insertion of a medical device into a vessel or organ. Methods of using the devices herein are also disclosed.

Introducer/dilator with balloon protection and methods of use

A cannula system having an internally slidable elongate tubular member frictionally anchored within a trocar, and optionally including a flange which acts as a positive stop against the trocar, that can be deployed for various treatments, including aortic cannulation during cardiopulmonary bypass, for example during CABG surgery. The tubular member has a proximal end, a lumen, and a flexible distal end which carries a preformed angled configuration relative to its proximal region and is bendable to a substantially linear configuration. The rigid trocar maintains the cannula in a substantially linear configuration. When the cannula is advanced through the lumen beyond the distal end of the trocar, the tubular member regains its angled configuration. Methods for using the devices herein are also disclosed.

Slideable cannula and method of use

The invention provides devices and methods for endoscopically cannulating the aorta, right atrium, and other body tissues to establish cardiopulmonary bypass for minimally invasive coronary artery bypass grafting surgery, and for other surgeries. After inserting the suction support through a minimal access port, the suction support having an arcuate member with suction ports provides countertraction to the aorta by creating a vacuum seal between its suction ports and the aorta, therefore facilitating aortic incision and cannulation. In one embodiment, the suction support allows aorta stabilization, incision, and insertion with an introducer to be achieved sequentially. Methods for using the devices herein are also disclosed.
