A balloon expandable anchor for a medical device. The anchor barb is contained within the device compacted delivery profile and is balloon expanded to rest outside of the expanded device profile.

Medical device fixation anchor suited for balloon expandable stents

An insect dissuasion device that incorporates a miniature fly swatter adapted to be fixed onto an end of a human finger. An insect can be discouraged by simply flexing, slowly encroaching upon and then 'flicking' the finger with the attached device to strike the insect. Devices of the present invention are designed to be removably attached to a finger by a ring-like structure. The ring-like structure is tailored to slip onto and engage a finger in various positions and remain attached to the finger when the finger is flicked. Joined to the ring-like structure is an extension shaft that terminates in an insect engagement head. The length and/or cross-sectional profile of the extension shaft can be altered as well as the shape of the head portion or ring-like structure.

Finger mounted insect dissuasion device and method of use

A buttress for use with circular surgical staplers that does not require adhesive to securely fasten the buttress to the stapler. Following cutting and stapling by the circular stapler, the buttress has an adaptive opening through its central region with a diameter smaller than the outer diameter of the stapler anvil. Because of relief features built into the buttress, the stapler anvil may be pulled through the buttress material without causing permanent alteration to the buttress. These relief features may be provided regardless of whether the buttress is made of inelastic or elastic materials. The buttress is generally circular in shape with an outer diameter sized to coincide with the outer diameter of the stapler body staple compression surface and the outer diameter of the anvil compression surface of a circular stapler with which it is used. Prior to surgical use, the buttress is attached to the stapler with disruptable portions extending from outer perimetal areas of the buttress.

A method of making a left ventricular assist device (LVAD) using muscle wrapped around a mandrel to form a muscle pouch, the open end of which is sewn to a circular sheet of patch material having connections to one end of each of a pair of vascular grafts, or alternatively to one end of a single vascular graft. The second ends of these vascular grafts are used to connect the LVAD to the aorta. After the muscle pouch has been formed around the mandrel, the mandrel is removed and replaced by a balloon which is inserted into the muscle pouch and inflated to maintain the desired shape of the muscle pouch during healing and stimulation of the pouch. The balloon is subsequently removed preceding activation of the LVAD to allow it to begin pumping blood. Alternatively, various other shape-maintaining forms which are expandable and collapsible may be used in place of the balloon. In an alternative embodiment, an additional strip of latissimus dorsi or other appropriate muscle or a mechanical clamping device may be used to synchronously compress the aorta between the ends of the vascular grafts anastomosed to the aorta.

Method of maintaining a left ventricular assist device

A surgical pledget dispensing system wherein a pledget is affixed to at least one other object whereby the pledget is tearably releasable from the at least one other object. Preferably a multiplicity of pledgers are affixed to the at least one other object in a tearably releasable fashion. The at least one other object is preferably at least one runner, a portion of a suture package or at least one other pledget.

The assembly is for use with closures located in top and bottom tracks, wherein at least one of the closures is slidable in the tracks between an open and a closed position. The assembly includes an elongated rod member which is swingably attached to the top track and has up and down positions. The assembly is designed such that when the rod member is in the down position, it extends between the edge of the slidable closure and the side of the opening in which the closures are located. This prevents the slidable closure from being moved from the closed to the open position. The security latch assembly also includes a latching assembly which is attached to a wall adjacent to the closures. There is an extension member which is attached to the rod member and extends beyond the closures to the latching assembly. The extension member engages the latching assembly and holds the rod member in either the up or down position. In certain embodiments, if the invention is employed with two slidable closures, the rod member has an end member attached thereto which interfaces with the second slidable closure when the rod member is in the down position and prevents the second closure from being slid within the tracks. In yet other embodiments, the assembly is employed with a pair of security doors which can be placed adjacent and parallel to a pair of sliding glass doors.
