The present invention provides a system and method for forming a side branch on a hollow vessel, such as the aorta. The side branch is preferably adapted to be connected to a connector conduit, but any other suitable use is also acceptable. The system comprises a graft including a side branch portion, and an applicator comprising a hole forming element adapted to form a hole in the wall of the vessel and an insertion element adapted to be inserted through the wall of the vessel, the insertion element comprising a retraction element adapted to enter into engagement with the graft. The hole forming element may comprise a cutting element adapted to cut a hole in the wall of the vessel, and a positioning element adapted to hold the position of the applicator relative to the vessel. The system further comprises a graft protection element adapted to prevent the graft from being damaged by the cutting element. In this case, the clamping element and the graft protection element may be the same element, for example, an expansion element, which may be expandable from an unexpanded state to fully expanded state and to a partially expanded state. The expansion element may be a balloon, which may be in the shape of a circular toroid, and may include a tension member that restricts the dimensions of the balloon. In addition, the expansion element may be an umbrella mechanism.

Apparatus and method for connecting a conduit to a hollow vessel

An apparatus and method for connecting a first conduit to the heart without the need for cardiopulmonary bypass. The first conduit may then be attached to a second conduit that has a prosthetic device interposed. The second conduit may then be connected to the aorta. The prosthetic device may be a prosthetic valve or a pump, for example. The apparatus of the present invention includes an implantable connector with first conduit component, a retractor expansion component, a coring component, and a pushing component. The retractor expansion component is slide-ably coupled to the coring component. The retractor expansion component serves to seat against and separate the inside apical wall of the left ventricle so that the coring component may cut cleanly through the myocardium to form a tissue plug without leaving any hanging attachments to the inside walls. By remaining seated against the inside wall, the retractor expansion component follows the tissue plug into the coring component. The surgeon applies force and rotary motion to the pushing component sufficient to cut the tissue plug and implant the prosthetic component.

Novel component devices for urine management systems including a novel collection device, a novel conveyance tube, and a novel storage container. The collection device, a novel male catheter, comprises a waterproof, thin-walled conduction tube surrounding the penis, having wettable internal walls and containing a spacing wick. At one end, the conduction tube is connected to, or surrounded by, an elastic compression tube that provides a uniform compressive force around the girth of the penis for attachment and liquid seal to said penis, and at the other end is attached to a fitting that connects to the conveyance tube. The elastic compression tube is radially expanded prior to donning and, when in place over the penis, is allowed to elastically retract, providing radial compression for comfortable, and leak-free fit and use. The conveyance tube, which carries urine from collector to storage container, contains a spacer throughout its length to prevent the tube lumen from being completely closed and sealed off by kinks or twists in the tube. Said tube may be a thin-wall flat tube that can conform to the body shape of the wearer, can expand in cross-section as flow rate increases, and can shrink and flatten as flow rate drops off. Urine is retained as immobilized material in a storage container that can be either replaced and disposed of or emptied and reused with cleaning as needed. The storage container's internal structure also provides a means for unique fluid transfer and retention capabilities. A system comprised entirely of said novel devices, serially and contiguously connected, forms a continuous liquid pathway that enables removal of residual pools of urine, as well as transport and storage of urine at locations that are gravitationally higher than the source.

A device for retracting edges of an incision in a surface to form an opening including: a flexible, tubular skirt having an upper end, a lower end, and a channel therebetween; a ring connected to the lower end of the skirt for maintaining the lower end in an open configuration and defining an exit opening to the channel; and an inflatable collar connected to the skirt and surrounding the upper end. The ring is designed to fit through the incision and remain under the surface when it is oriented parallel to surface. The collar, when inflated, maintains the upper end in an open configuration and defines an entry opening to the channel. During use, the ring is inserted through the incision and the collar is inflated while remaining outside of the incision, thereby drawing the skirt against the edges of the incision and retracting the edges of the incision to form the opening. The retracting device can be included in a surgical access port, which further includes a flexible sleeve connected to at least one of the inflatable collar and the skirt, extending the channel from the exit opening of the skirt to an open end of the flexible sleeve distal to the skirt. The device can include a light source in the vicinity of the exit opening.
