摘要： The invention relates to a device for the trans-anal insertion of an infusion into the rectum or colon of a patient, comprising an inflatable balloon which has a predefined waisted shape, in particular a shape of a dumbbell or an hour glass, and two terminal balloon sections having a larger radius and an interposed balloon section that has a reduced radius and is placed in a trans-anal manner, such that the distally adjoining, radially enlarged balloon section is placed in an intra-rectal manner and the proximally adjoining, radially enlarged balloon section is placed in an extra-corporal manner, both balloon ends tapering to the dimension of the shaft of the catheter shaft supporting the balloon and being fixed in a simple reversed manner on the jacket surface of the catheter shaft so that both radially enlarged balloon sections displace each other in opposite axial directions toward each other when the balloon is filled. Both radially enlarged balloon sections are enlarged relative to the tapered, central balloon section such that the two radially enlarged balloon sections of the balloon, which was placed in a trans-anal manner, are put over the radially tapered balloon section when the balloon is filled and, in the limiting case, come into direct contact with each other, thereby limiting their relative movement and preventing the distal end of the catheter shaft to exceed the apex point of the intra-rectal balloon radius in the event of a maximum deflected position of the shaft body. The invention also relates to a method for filling the catheter balloon of such a device by means of a filling device, wherein the filling volume or the filling pressure in the balloon is increased in two or more steps until occurs a gradual, pneumatically initiated expansion of portions of the bowel wall, which is controlled by the user, thus leading to the triggering of a coordinated defecation reflex, whereby the timing and intensity of the triggered stimulus can be determined to the greatest possible extent by the user.

摘要： A balloon catheter device (20) comprises a catheter (26) having a proximal end (28), a distal end (30), and catheter walls (32) defining a catheter lumen (34). The device (20) further includes a base (36) located at the proximal end (28) of the catheter (26) defining an opening to the catheter lumen (34). An inflatable balloon (24) having a predetermined fill volume is located at a distal end (30) of the catheter. The inflatable balloon (24) contains a fluid under pressure upon inflation to its predetermined fill volume and after inflation further containing a reserve volume of fluid that is less than the predetermined fill volume when the fluid is no longer under pressure. An inflation valve (46) is located on the base (36); the inflation valve (46) is in fluid communication with the balloon (24). A pre-biased pressure indicator (22) is in fluid communication with the balloon (24). The pre-biased pressure indicator (22) comprises a non-electrical indicator responsive only to pressure communicated from the balloon (24) crossing a predetermined threshold pressure and providing only a first discrete visual signal when the balloon (24) is inflated to its predetermined fill volume and a second discrete visual signal when the fluid in the retainer balloon (24) is no longer under pressure, with no signal of other inflation states therebetween. The second discrete visual signal provides warning that the retainer balloon volume has reached the reserve volume.

摘要： An inflation device includes a syringe body containing a bore. The bore holds a fluid that is used to inflate a separate device such as a dilation balloon. A plunger assembly slides within the syringe bore and contains a sealing member that forms a fluid tight seal with the syringe body. A shut-off valve is disposed within the distal end of the syringe body. The distal end of the syringe body has a fluid bypass channel fluidically coupled to the aperture of a connector. The shut-off valve has a spring-biased moveable piston with a bypass lumen contained therein, wherein the bypass lumen forms a fluid path between the bore and the fluid bypass channel when the pressure of the fluid is below a threshold value. The fluid path between the bore and the fluid bypass channel is interrupted when the pressure of the fluid is above the threshold value.

摘要： A device (10) for treating esophageal target tissue comprises a catheter (18), a balloon (16) and a refrigerant delivery device (20). The catheter has a distal portion (38) and a refrigerant delivery lumen (22). The balloon is mounted to and the refrigerant delivery device is coupled to the distal portion. The refrigerant delivery device comprises a chamber with the refrigerant delivery lumen opening into the chamber, a refrigerant delivery opening (65) fluidly coupled to the balloon interior (30), and a distribution passageway (59) fluidly coupling the chamber and the refrigerant delivery opening. A refrigerant (24) is deliverable through the refrigerant delivery lumen, into the chamber, through the distribution passageway, through the refrigerant delivery opening and into the balloon interior so to place the balloon into an expanded, cooled state to press against and cool esophageal target tissue. The medical device may include means for sensing a leak in the balloon.

摘要： A method for performing an in-vivo calibration of a blood pressure sensor 40 that is associated with an in-vivo balloon system. The method involves monitoring a patient's blood pressure by observing the system gas pressure while at the same time monitoring the patient's blood pressure through the sensor. The blood pressure measurements obtained by monitoring the system gas pressure are used as reference, or 'true, ' blood pressure measurements, and an 'offset' is determined between the reference blood pressure measurements and the blood pressure measurements obtained through the sensor. The offset can be stored in a memory 42, which may also store sensor sensitivity data. The offset and/or sensitivity data may be used to adjust future measurements obtained from the sensor, thereby generating calibrated sensor measurements.

摘要： The invention relates to an inflation device (1) for inflating an expansible surgical implant (2), wherein said implant (2) is to be positioned inside the body of a human or an animal and is capable of changing, by supplying a filling fluid, from a deflated configuration to an inflated configuration in which it assumes a predetermined volume, said inflation device (1) being characterised in that it comprises a cartridge (3) adapted to be connected with the implant (2) for inflating the same, said cartridge (3) containing a predetermined amount of inflating fluid that does not exceed the amount of inflating fluid to be contained in the implant (2) for the latter to reach its predetermined volume, and in that it comprises an inflation end piece (4) including a means for adjusting the flow (5) of the filling fluid fed into the implant (2). The invention can be used in devices for inflating surgical implants.
