Abstract: A total dose of a therapeutic agent to be delivered to a patient by an infusion device over a total period of time is automatically divided into a plurality of unit doses to be delivered to the patient over a plurality of unit periods of time. The infusion device is automatically programmed to deliver one of the unit doses of the therapeutic agent to the patient over its respective unit period of time, after which the one unit dose is delivered, and a determination is made of whether an error occurred in delivering the one unit dose to the patient. Delivery of the total dose of the therapeutic agent to the patient may include iteratively automatically programming the infusion device to deliver successive unit doses upon determining that no error occurred in delivering a previous unit dose to the patient. Accordingly, the risk of improperly dosing the patient with the therapeutic agent in an event of a software or hardware anomaly within the infusion device is prevented or reduced.

Abstract: Medical systems are described herein. More particularly, the disclosure relates to medical systems, methods, and kits useful in providing the diameter of a balloon during the performance of a procedure. An exemplary medical system comprises a balloon catheter, an inflation device, and a measuring device having one or more indicia. Each indicium of the one or more indicia has a form that corresponds to the nominal value of a balloon diameter.

Abstract: An apparatus provides feedback regarding the material in which tip of the apparatus is located as the tip is advanced into matter of varying resistances. The apparatus responds to a change in pressure, force, or other parameter such that when the tip reaches matter of a certain resistance, a change in the parameter is sensed. The apparatus provides a driving force to a penetrating medical device, such as a needle, when the apparatus tip encounters material of high resistance. When the apparatus tip encounters a low resistance material, no further driving force is applied to the apparatus. An inner core may be advanced into the low resistance material for deployment of a gas or a liquid as desired.

Abstract: A catheter can efficiently transmit an operator's pushing force to a distal end of the catheter with a reduced risk of getting caught at a curved region of a lumen (e.g., a blood vessel, bile duct, pancreatic duct or the like). The catheter includes a first core wire and a second core wire disposed between an inner tube and an outer tube. The second core wire can move to an optimal position depending on external forces exerted at a curved region of the lumen when the catheter is inserted into the curved region. Therefore, there is a reduced risk that the first core wire and the second core wire will interfere with each other, which would prevent the catheter from bending along the lumen and potentially break one or both of the first core wire and the second core wire.

Abstract: A trigger assembly for an automatic injection device which by its operation releases a biased element of the device for movement. The trigger assembly includes a button pressable by a user, and a lock member. Prior to the button being plunged, a blocking element on the button is abutted by a button-engaging surface of the lock member to prevent lock member rotation, thereby allowing an engagement surface on the lock member to remain in engagement with an engagement surface of the biased element so as to restrain motion of the biased element. When the button is plunged, the blocking surface moves clear of the button-engaging surface to allow the lock member to rotate, during which rotation the engagement surfaces disengage to release the biased element for movement.
