Drug delivery methods having an occluding member

Drug depot delivery devices and methods for delivering a drug depot to a site beneath the skin of a patient are provided. In various embodiments the device has a housing having a top housing end, and a bottom housing end. The housing defines a housing channel. The device has a drug cartridge defining a depot channel aligned with the housing channel and configured to slidably accept the drug depot. The drug cartridge has at least a first occluding device configured to occlude the depot channel at a first position such that the drug depot cannot pass through the depot channel without force applied to the drug depot sufficient to deflect the first occluding device. The bottom end of the housing has a coupling configuration for engaging a cannula. A plunger has a push rod to expel the drug depot through the occluding device and the cannula.

System and method for delivering a catheter

A method of delivering a catheter to a location of interest in the vasculature, the method including positioning a self-expanding sheath within a lumen of the catheter; advancing the catheter and the self-expanding sheath in tandem over a guidewire; and distally moving a distal end of the self-expanding sheath out from the lumen of the catheter thereby causing the self-expanding sheath to move from a collapsed state within the catheter to an expanded state outside the catheter, wherein when the self-expanding sheath is in the expanded state both the self-expanding sheath and the catheter are distally advanceable in tandem.

20230139854 · 2023-05-04 ·

A urinary catheter may include a catheter shaft and a connector coupled with the proximal end of the catheter shaft. The connector may have a first arm ending in a fluid outlet configured to allow urine to flow out of the urinary catheter and a second arm with an aperture and ending in an inflation inlet used for introducing inflation fluid into the urinary catheter. The catheter may further include a primary lumen, an inflation lumen, a retention balloon mounted to the catheter shaft proximal to a fluid inlet and over a distal filling hole, and a pilot balloon mounted on the second arm of the connector over the aperture. The pilot balloon inflates at an inflation pressure that is higher than the inflation pressure of the retention balloon and lower than a predetermined pressure threshold.

BALLOON CATHETER WITH CENTRALIZED VENT HOLE
20170361073 · 2017-12-21 ·

A system and method providing a catheter assembly for engaging a stenosis. The assembly includes a catheter defining a first lumen and a second lumen spaced apart and disposed about a longitudinal axis. The catheter includes an opening in communication with the first lumen to define a flow path having an angle incident to the longitudinal axis. A first marker; and a second marker disposed on the catheter are spaced equidistantly from the opening. The assembly includes a balloon having a first end and a second end each sealed about the catheter and equidistantly from the opening to define a holding volume therebetween. The opening is disposed within the holding volume thereby placing the first lumen in sealed fluid communication with the holding volume. In a preferred embodiment, the catheter assembly includes a stem disposed about the balloon, and the balloon is configured to engage the stent with a stenosis.

Cardiac treatment system and method

Devices and methods for providing localized pressure to a region of a patient's heart to improve heart functioning, including: (a) a jacket made of a flexible biocompatible material, the jacket having an open top end that is received around the heart and a bottom portion that is received around the apex of the heart; and (b) at least one inflatable bladder disposed on an interior surface of the jacket, the inflatable bladder having an inelastic outer surface positioned adjacent to the jacket and an elastic inner surface such that inflation of the bladder causes the bladder to deform substantially inwardly to exert localized pressure against a region of the heart.

Microcatheter system
