Bladder rolling machine

An apparatus for rolling a bladder includes a support structure, a rolling pin, and a bladder-mounting pin. The apparatus optionally includes a rolling initiator Rolling a bladder includes inserting the bladder while unrolled into an apparatus for rolling a bladder, inserting the bladder between a rolling pin and a bladder-mounting pin of the rolling machine, and rotating the rolling pin to (a) advance a portion of the bladder between the rolling pin and the bladder-mounting pin, (b) roll the portion of the bladder around the bladder-mounting pin, and (c) drive the bladder-mounting pin to rotate in an opposite direction from that of the rolling pin.

Drug eluting balloon

The present invention is an inflatable balloon which is enclosed by an expandable cover which becomes increasingly porous/permeable during expansion. The balloon is coated or enclosed with a matrix which contains a pharmaceutically active agent. During expansion of the balloon, the pharmaceutically active agent is released or extruded through the expandable cover into a body cavity such as an artery or vein. The present invention also provides for a method of treating a disease or condition by delivering the inflatable balloon to a particular body cavity.

Medical Device Insertion Apparatus, System and Method

An insertion device is disclosed. The insertion device includes a base portion, a top portion slidably connected to the base portion, an introduction needle, a catheter in slidable relation to the introduction needle, and a substantially cylindrical flash chamber, the flash chamber having an inlet in fluid communication with the introduction needle. The flash chamber is connected to the base portion, the top portion slidably engages with the flash chamber, and the catheter and the top portion slidably advance with respect to the introduction needle and the base portion.

Multi-balloon instrument for dilating eustachian tube via middle ear
11559673 · 2023-01-24 · ·

A dilation catheter includes a shaft, a distal tip sized and configured to pass through an isthmus of a Eustachian tube (ET), and an expandable element moveable along an exterior of the shaft between a proximal position and a distal position. The expandable element is operable to transition between an unexpanded state in which the expandable element is configured for insertion into the ET via the isthmus, and an expanded state in which the expandable element is configured to dilate the ET.

Cannula delivery catheter and procedure method

The medical device may comprise an elongate body having a proximal portion, a distal portion, and defining a lumen therethrough. Also, the medical device may include an expandable element coupled to the distal portion of the elongate body and in fluid communication with the lumen. The expandable element may define a first end and a second end, the second end being proximal to the first end. The medical device may further include a cannula surrounding at least a portion of the elongate body and the cannula may define a proximal end and a distal end. The distal end of the cannula may be disposed proximal and adjacent to the second end of the expandable element. An outer dimctcr diameter of the cannula may be substantially equal to or lesser than an outer diameter of the expandable element when inflated. The medical device may be maneuvered through a patient's body.

Urinary catheter-insertion kits can include a working tray, a storage tray, a protective paperboard, and a urinary catheter assembly, including a urinary catheter and a drainage system. The working tray can be nested on top of the storage tray. The working tray includes preformed sections configured to accommodate components of the urinary catheter-insertion kit. Methods of urinary catheterization include use of the urinary catheter-insertion kits.

Drug-elution control sleeve for drug-eluting balloon and method

An apparatus, assembly and method for controlling release of a drug from a drug-eluting balloon during delivery of a drug-eluting balloon to a situs within a body. More particularly, the present invention relates to a diametrically expandable sleeve having a first non-diametrically unexpanded state in which drug retained on or in a drug-eluting balloon is protected from release by a sleeve and a second diametrically expanded state in which drug retained on or in the drug-eluting balloon is exposed for focal release in the body by diametric expansion of the sleeve, exposing openings in the sleeve during diametric expansion and closing the openings in the sleeve when the sleeve is in its diametrically unexpanded state.
