The devices utilized to deliver the implantable medical devices may be modified to reduce the potential for damaging the implantable medical device during deployment.

An anchoring system for securing a dialysis catheter to a patient comprises an anchor pad and a retainer. The anchor pad is attached to the skin of the patient by an adhesive layer on one side of the pad. The retainer is disposed upon the surface of the anchor pad opposite the adhesive layer and includes a base and a cover and a adhesive spot. A groove upon the base is arranged to receive a Y-site portion of a dialysis catheter where the lumens merge distal to the insertion site. A post also protrudes from the base to the cover at a position which will be disposed between the two distal branches of the dialysis catheter. The cover closes over the base, securing the Y-site between the groove and the post. Closing the cover also places at least a portion of the catheter in contact with the adhesive spot. This contact between the retainer, adhesive spot and catheter thereby inhibits inadvertent motion of the catheter upon the patient. A latch mechanism is disposed upon the retainer to maintain the cover in a closed position over the Y-site of the catheter on the base.

Methods of treatment using a gastrointestinal implant device removably anchored within an animal's gastrointestinal tract. For example, the implant device includes a collapsible anchor for anchoring the device coupled to a proximal end of a flexible sleeve. The implant device can be anchored within the stomach, within the pyloric orifice, and / or distal to the pylorus and extended into the duodenum. All partially-digested food, or chyme, exiting the stomach is funneled through the device. Methods of treatment include treating obesity by one or more of: limiting the absorption of nutrients within the duodenum; delaying the mixing of chyme with digestive enzymes; alter hormonal triggers; and providing negative feedback. Alternatively or in addition, the desired result includes treating a diseases, such as diabetes, or temporarily shielding a portion of the intestine to promote healing within the intestine.

An electrosurgical pencil includes an adjustable-length suction tube which surrounds a stationary electrode to evacuate smoke and electrosurgical byproducts from a surgical site. An electrode anchor unit is located within the interior of the suction tube to allow relative movement of the suction tube relative to a stationarily-retained electrode, and to receive and connect to different lengths of the electrodes. Adjusting the length of the suction tube relative to the different lengths of the electrode achieves effective evacuation, among other things.

An infant carrier and car seat combination is illustrated which provides releasable lockability between the carrier and its base, infant seat belt tensioning and height adjustment, improved handle movement which resists twisting and carrier base adjustment through a movable base within the carrier base.

A method of making a stent delivery system is provided in which a delivery catheter has a balloon that extends non-uniformly into interstices of a stent. In accordance with the method a balloon / stent / crimping tube assembly is placed in a crimping tool, the balloon is inflated, and the crimping tool is actuated to compress the stent on the outside of the balloon without application of heat or chemicals, thereby causing creases of the balloon to extend non-uniformly into the interstices of the stent. Optionally, pillows may be formed in the balloon to prevent longitudinal movement of the stent with respect to the balloon during intravascular delivery. One or more secondary crimpings also may be performed to achieve a smoother delivery profile.

A polymeric, surgical clip having first and second curved leg members joined at their proximal end by a hinge portion and movable from an open position to a closed position for clamping a vessel between curved opposing inner surfaces which are substantially parallel when the clip is closed. An interlocking mechanism is formed by a portion of the inner surfaces of the first and second legs. The interlocking mechanism may be a tongue-in-groove mechanism, formed by a lip or tongue protruding from a portion of the inner surface of one leg and a groove formed in a corresponding portion of the inner surface of the other leg, or a lock-step mechanism, formed by complementary L-shaped notches wherein a notch is provided in a portion of the inner surface of each leg. The interlocking mechanism acts to impede longitudinal movement of the clip relative to the vessel being clamped.

Method and apparatus for limiting absorption of food products in specific parts of the digestive system is presented. A gastrointestinal implant device is anchored in the stomach and extends beyond the ligament of Treitz. All food exiting the stomach is funneled through the device. The gastrointestinal device includes an anchor for anchoring the device to the stomach and a flexible sleeve. When implanted within the intestine, the sleeve can limit the absorption of nutrients, delay the mixing of chyme with digestive enzymes, altering hormonal triggers, providing negative feedback, and combinations thereof. The anchor is collapsible for endoscopic delivery and removal.

A modular flooring system includes a plurality of floor tiles situated about a ground surface, with each floor tile having a substantially-flat top surface and a connection interface with opposing engagement surfaces. The flooring system also includes a plurality of removable bridge connectors, with each of the bridge connectors having a plurality of tile interfaces, and with each tile interface having complimentary engagement surfaces configured to engage with the opposing engagement surfaces of the connection interfaces. The tile interfaces of the bridge connectors couple to the respective connection interfaces of any adjacent floor tiles to restrain the relative vertical movement between the adjacent floor tiles while facilitating controlled relative lateral movement between the floor tiles.

A rear peep sight for mounting to a string of a bow and having interchangeable sight ports for accommodating different user preferences. A mounting member mounts to the string of the bow and a sighting member is interchangeably attached to the mounting member so as to accommodate different user preferences of sight ports. The mounting member has a channel that slidably receives the sighting member so as to provide a dove-tail joint that prevents the sighting member from vertical movement, yet allows for horizontal movement so as to allow the sighting member to slide sideways into the channel. The sighting member has an auxiliary through bore and a pimple that align with, and engage with, respectively, a pair of through bores in the mounting member. A screw extends freely through one through bore in the mounting member and threadably into the auxiliary through bore so as to maintain prevention of the sighting member from horizontal movement.
