Medical inflation systems and methods
Devices used to pressurize, depressurize, or otherwise displace fluid are disclosed. The devices may be configured to displace fluid in order to inflate or deflate a medical device, such as a balloon. The devices further include a crank member for providing a mechanical advantage when pressurizing or otherwise displacing fluid.
Balloon dilator
A dilator system for arterial and venous cannulas, where there is a smooth transition between the dilator and the outer wall of the cannula. One aspect of the subject technology provides a blunt-tip cannula that is used as a dilator for insertion of an arterial or venous cannula. The balloon might either be a single diameter or may have a larger diameter at the distal portion such that the diameter of the distal portion of the balloon dilator matches the diameter of the cannula at the tip. Another aspect of the subject technology is a balloon dilator for cannulae that may be positioned over a guidewire, for guidewire-directed placement of a cannula within a vessel, duct, lumen or heart structure of the body. Another aspect of the subject technology is an inflation system for the balloon dilator, such that the balloon dilator may be deflated and quickly removed from the cannula after the cannula has been positioned and secured within the vessel, duct, lumen or heart structure. Another aspect of the subject technology includes a stiffening element in the balloon dilator along its shaft to increase the rigidity of the combined balloon dilator and cannula to provide improved ease of insertion. Another aspect of the subject technology is an improved curvature of the shape of the right angle dilator that achieves more uniform flow within the dilator and ease of insertion and more even flow within the cannula, and ease of insertion of and retraction of the balloon dilator. Another aspect of the subject technology is a gel-filled balloon dilator that improves ease of insertion of the cannula within the vessel, duct, lumen or heart structure, and can be removed without deflation.
IMPLANTABLE MEDICAL SYSTEM
A system includes a lead with a balloon, wherein the lead defines an inflation lumen in fluid communication with the balloon. The system further includes an implantable medical device with a housing defining a fastener opening and a lead lumen. The lead lumen is configured to receive a proximal portion of the lead. The system further includes a fastener defining a fastener lumen. The fastener is configured to engage the fastener opening and the proximal portion of the lead to retain the proximal portion within the lead lumen. The fastener lumen is in fluid communication with the lead lumen and the inflation lumen, such that a pump in fluid communication with the fastener lumen inflates the balloon when the proximal portion of the lead is within the lead lumen.
ADVANCED ACTUATING MECHANISM AND METHOD OF OPERATION FOR FLUID DISPLACEMENT AND PRESSURIZING DEVICE
A fluid displacement and pressurizing device which includes a housing, a first piston in the housing, a plunger which extends from the housing and has a second piston thereon, and an actuator that works to selectively lock the piston to either the housing or the plunger depending on the position of the second piston in the housing. Effectively, the actuator includes a first locking mechanism that locks and unlocks the first piston relative to the housing and a second locking mechanism that locks and unlocks the plunger relative to the piston. As such, the first locking mechanism is not only a locking mechanism but is also an actuating mechanism with regard to actuating the second locking mechanism.
Systems and Methods for Sinus Access
This application is generally related to systems and methods for accessing the paranasal sinuses and other passages of the nose, ear, and throat. The systems and methods generally employ devices capable of maintaining a fixed handle orientation with respect to the patient while generating the appropriate applicator deflection angle required to rotationally align or orient the applicator tip to the intended target tissue/anatomy for treatment. Methods are also described for deploying drug delivery devices within these body structures using the systems to treat medical conditions associated therewith.
Urinary Catheter-Insertion Kits
Urinary catheter-insertion kits can include an upper tray fixed to a lower tray and a separator wall positioned over at least a portion of the urinary catheter assembly. The upper tray can include a preformed catheter section configured to accommodate a urinary catheter of a urinary catheter assembly, and a cutout formed through an end portion of the catheter section. A drainage system of the urinary catheter assembly can be disposed in the lower tray, the drainage system including drainage tubing and a drainage receptacle. The drainage tubing can be connected to the urinary catheter through the cutout in the catheter section of the upper tray. Methods of urinary catheterization include use of the urinary catheter-insertion kits.
PRESSURE RELIEF FOR A CATHETER BALLOON DEVICE
A method of limiting an inflation system pressure for dilating a region of a patient’s nasal sinus passageways. The method includes grasping an inflation device. The inflation device includes a syringe including a plunger slidably disposed within a barrel, a connector for fluidly connecting an outlet of the syringe with a surgical instrument balloon, and a mechanical pressure indicator associated with the syringe, the mechanical pressure indicator including a housing and an indicator body disposed within the housing. The method also includes delivering the surgical instrument balloon to a patient’s paranasal sinus target area, operating the plunger within the barrel of the syringe to deliver pressurized fluid to the surgical instrument balloon, and transitioning the indicator body to extend outside of the housing when a predetermined inflation pressure of the surgical instrument balloon is reached.
Kyphoplasty system and method
A kyphoplasty system disclosed herein includes various instruments which can be selectively used to perform a kyphoplasty operation on a patient. For example, in some embodiments the kyphoplasty system includes an inflation plunger that is used to deliver a balloon inflation medium to enlarge an implantable balloon device. Further, some embodiments described herein include a connection system between the implantable balloon device and its delivery shaft that is simple to construct and easy to use. For example, in some embodiments one or more sutures are used to releasably connect the implantable balloon device to its delivery shaft.
