DETAILED DESCRIPTION [0028] While this invention may be embodied in many different forms, there are described in detail herein specific preferred embodiments of the invention. This description is an exemplification of the principles of the invention and is not intended to limit the invention to the particular embodiments illustrated. [0029] A medical device delivery system is shown generally at 100 in FIG. 1. Medical device delivery system has a proximal end 102 and a distal end 104. Manifold 106 is provided at proximal end 102. Inner tube 108 extends distally from manifold 106. The inner tube includes a medical device receiving region 110, desirably towards the distal end of inner tube 108. Inner tube 108 terminates at the distal end in a tip 112. Tip 112 may be integrally formed with the inner tube or may be bonded to the inner tube using any suitable bonding technique including adhesive bonding, heat welding or laser bonding. A retractable sheath 114 is disposed about the distal end of inner tube 108. Pull wire 116 extends proximally from retractable sheath 114 to the region of manifold 106. Retractable sheath 114 may be retracted by pulling pull wire 116 in the proximal direction. [0030] Medical device delivery system 100 further comprises a shape memory metal bumper 118 disposed about the inner tube adjacent to medical device receiving region 110. Desirably, the shape memory bumper is adjacent the proximal end of the medical device receiving region. Shape memory metal bumper 118 may be affixed to inner tube 108 using any suitable adhesive or using any other suitable method for affixing a bumper to a tube. Shape memory metal bumper is transformable between a reduced profile configuration, as shown in greater detail in FIGS. 2-3 and an increased profile configuration, as shown in greater detail in FIGS. 4-7. In the embodiment of FIGS. 2-7, shape memory metal bumper 18 is in the form of a tube having a slotted portion 120 and a non-slotted portion 122. Shape memory metal bumper 118 is shown in FIGS. 4-5 as it transitions from the reduced profile configuration to the increased profile configuration. Slotted portion 120 of tube 118 is partially open. In FIGS. 6-7, slotted portion 120 of tube 118 is fully open. In the fully open configuration, the shape memory metal bumper may optionally extend radially outward from the inner tube to a distance in excess of the stent. [0031] Any of the medical device delivery systems disclosed herein may also be provided with two shape memory metal bumpers with one of the shape memory metal bumpers proximal to the medical device or stent and the other shape memory metal bumper distal to the medical device or stent. [0032] Shape memory metal bumpers having other shapes may also be used. For example, one or more arcuate shape memory metal bumpers which do not extend all the way around the inner tube may be used. More generally any shape memory metal bumper of any shape may be used as long as the bumper has a reduced profile configuration in which the bumper may be passed through the flow passage of a stent or other medical device and an increased profile configuration in which it cannot pass through the flow passage of a medical device such as a stent. [0033] Shape memory metal bumper 118 may be made of any suitable, biocompatible shape memory metal. Examples of shape memory metals which may be used include nickel-titanium alloy, generically known as nitinol, copper- aluminum- nickel, copper-zinc-aluminum and iron-manganese-silicon alloys. [0034] Desirably, the shape memory metal bumper will be made of Nitinol. Nitinol has two phase, a martensitic phase and an austenitic phase. A slotted tube of Nitinol may be formed to a desired shape such as that shown in FIGS. 6 and 7 and the shape heat set into position. The Nitinol may then be cooled while maintaining its shape and then plastically deformed to a new shape such as that shown in FIGS. 2 and 3. Upon subsequent heating, the metal will return to the shape it originally had prior to plastic deformation at the cold temperature. [0035] Medical device delivery system 100 may be used to deliver a variety of implantable medical devices including stents and vena cava filters. It is noted that for the purposes of this disclosure, the term stent is understood to refer to stents, grafts, stent-grafts and other expandable prostheses. As shown in FIG. 1, stent 124 is disposed about medical device receiving region 110 of inner tube 108. Stent 124 is desirably a self-expanding stent. An example of a suitable stent for use with the medical device delivery system is a shape memory metal stent such as the Scimed Radius™ stent disclosed in WO 96/26689. [0036] The inventive medical device delivery systems may also be modified for use with balloon expandable stents by providing an inflatable medical balloon in the medical device receiving region and an inflation lumen for supplying an inflation fluid to the balloon. An example of a medical device delivery system with a balloon is shown in commonly assigned U.S. Pat. No. 5,989,280. [0037] The inventive medical device delivery systems described above may be provided in an over-the-wire configuration, a rapid exchange configuration or a fixed wire configuration. Examples of catheters with such configurations are disclosed in U.S. Pat. No. 5,980,533 and U.S. Pat. No. 5,957,930. [0038] The present invention is also directed to a method of preparing a delivery system for delivering an implantable medical device. In accordance with the inventive method, as shown in FIG. 8a, a tube 108 having a proximal end and a distal end is provided. The distal end of tube 108 terminates in an enlarged tip 112. Tube 108 has a bumper 118 formed of a shape memory metal proximal to tip 118. Bumper 118 is expandable from a reduced profile state to an increased profile state. An implantable medical device having a flow passage therethrough sized to allow passage of the bumper in the reduced profile state therethrough, such as stent 124, is provided. As further shown in FIG. 8a, the implantable medical device is passed about the bumper in the reduced profile state 118 a and the implantable medical device disposed about the inner tube adjacent to the bumper, between the bumper and the tip. Finally, the bumper is caused to transition from the reduced profile state to a partially increased profile state 118 b as shown in FIG. 8b, and then to the fully increased profile state 118 c as shown in FIG. 8c. [0039] The transitioning of the bumper to the increased profile configuration may be caused by increasing the temperature of the bumper. Where the bumper is made of a shape memory metal having a martensitic state and an austenitic state with associated austenitic start and finish temperatures, the temperature of the bumper may be increased to a temperature exceeding the austenitic start temperature thereby causing the bumper to transition from the reduced profile state to the increased profile state. The specific type of Nitinol should be chosen such that the austenitic start or finish temperature is not so high that the tube would be damaged by heating the bumper. [0040] The inventive method may optionally further comprise the step of providing a manifold to the proximal end of the inner tube subsequent to disposing the medical device adjacent to the bumper. Moreover, the method may optionally include the step of providing a retractable sheath about the implantable medical device prior to or subsequent to disposing the implantable medical device about the inner tube adjacent to the bumper. [0041] The inventive method may be used in conjunction with a variety of implantable medical devices including stents. [0042] In another embodiment, as shown in FIGS. 1 and 9, the invention is directed to a medical device delivery system shown generally at 100 comprising a manifold 106 with an inner tube 108 extending proximally therefrom. A retractable sheath 114 is disposed about the distal end of inner tube 108. A pull wire 116 extends proximally from retractable sheath 114 to manifold 106. Manifold 106 includes a rack 158 and pinion 162. Rack 158 is movable in a proximal direction. Pinion 162, shown in greater detail in FIGS. 10 and 11, includes a gear portion 170 having a plurality of teeth 172 disposed about the periphery and a shaft portion 174 which serves as a spool for taking up the pull wire. Pinion 162 may optionally be provided with an enlarged end 176 to aid in retaining the pull wire on spool portion 174. Rack 158, as shown in FIG. 12, comprises a plurality of teeth 178 arranged linearly thereon. As rack 158 is moved in the proximal direction, rack 158 engages pinion 162 and pull wire 116 is wound around spool portion 174 of pinion 162 thereby retracting retractable sheath 114. [0043] As the diameter of the spool portion of the pinion increases relative to the diameter of the gear portion, the mechanical advantage of the rack and pinion assembly increases reducing the length of rack necessary to retract the sheath by a fixed distance. While reducing the length of rack is desirable in that it allows for a reduced length manifold, if the mechanical advantage is excessive, the device will become more difficult to control as small, unintended displacements in the rack will result in large displacements of the retractable sheath. Moreover, as the mechanical advantage is increased, the force necessary to move the rack increases. Desirably, the ratio of the spool diameter to the gear diameter will range from 1:2 to 8:1 and more desirably, from 1:1 to 4:1. [0044] Manifold 106 comprises a first part 164 and a second part 166. First part 164 is movably received in second part 166. Rack 158 is attached to second part 166 while pinion 162 is attached to first part 164. The invention also contemplates the use of manifolds with different designs. For example, the rack and pinion may be mounted within a one-piece construction manifold. In such an embodiment, the rack would be moved relative to the manifold itself to retract the retractable sheath. [0045] Manifold 106 may, optionally, also slide in the distal direction. As the manifold slides in the distal direction, pull wire 116 unwinds from pinion 162. Desirably, a pull wire that is flexible enough to be wound and yet rigid enough to exert a pushing force to push the retractable sheath back into place as the pull wire unwinds will be used. [0046] As shown in FIG. 13, the medical device delivery system may also be arranged, by altering the direction that the spool is wound, so that retractable sheath 114 is retracted by sliding rack 158 in the distal direction. [0047] The embodiments of FIGS. 9 and 13 employ a spool which has a radius larger than that of the pinion to achieve a force advantage. In another embodiment, as shown in FIG. 14, the invention is directed to a medical device delivery system which employs a spool 174 having a radius smaller than that of pinion 162 to achieve a distance advantage. Less force is required to retract the sheath, however, the rack must be moved a greater distance. [0048] In the above embodiments, the pinion is fixed in place and the rack is movable relative to the pinion. The invention also contemplates embodiments in which the rack is fixed in place and the pinion is movable relative to the rack. An example of such an embodiment is shown in FIGS. 15 and 16. FIG. 15 is a top view of a portion of a manifold 106 in which rack 158 is fixed in place and pinion 162 is movable relative to rack 158. FIG. 16 is a side view of manifold 106. Spindle 182 extends outward from pinion 162 through longitudinal slot 184 in manifold 106. Desirably, spindle 182 spins freely in pinion 162. As spindle 182 is moved in a proximal direction, pinion 162 moves in a proximal direction winding pull wire 116 around shaft portion 174 of pinion 162 thereby retracting in a proximal direction a retractable sheath (not shown) attached to the distal end of pull wire 116. The rack and pinion of FIGS. 15 and 16 may also be arranged such that retraction of the retractable sheath results from moving the spindle in a distal direction. The diameter of the shaft portion of the pinion may be altered relative to the diameter of the gear portion to increase or decrease the mechanical advantage of the device, as discussed above. [0049] Where the inventive rack and pinion based medical device delivery system includes a bumper, the inventive shape memory bumper disclosed above may be used or any other suitable bumper may be used. [0050] The above disclosure is intended to be illustrative and not exhaustive. This description will suggest many variations and alternatives to one of ordinary skill in this art. All these alternatives and variations are intended to be included within the scope of the claims where the term “comprising” means “including, but not limited to”. Those familiar with the art may recognize other equivalents to the specific embodiments described herein which equivalents are also intended to be encompassed by the claims. [0051] Further, the particular features presented in the dependent claims can be combined with each other in other manners within the scope of the invention such that the invention should be recognized as also specifically directed to other embodiments having any other possible combination of the features of the dependent claims. For instance, for purposes of claim publication, any dependent claim which follows should be taken as alternatively written in a multiple dependent form from all prior claims which possess all antecedents referenced in such dependent claim if such multiple dependent format is an accepted format within the jurisdiction (e.g. each claim depending directly from claim 1 should be alternatively taken as depending from all previous claims). In jurisdictions where multiple dependent claim formats are restricted, the following dependent claims should each be also taken as alternatively written in each singly dependent claim format which creates a dependency from a prior antecedent-possessing claim other than the specific claim listed in such dependent claim below (e.g. claim 3 may be taken as alternatively dependent from claim 2; claim 4 may be taken as alternatively dependent on claim 1 or on claim 2; claim 5 may be taken as alternatively dependent from claims 2, 3 or 4; etc.).
