Said lateral conduits have an angle in the range of 15° to 60° to the longitudinal axis of the catheter.

Drug delivery device

A drug delivery device includes a blunt cannula and a reservoir. The blunt cannula has a cylindrical wall that defines an axial passage between a first end and a second end of the blunt cannula. The wall has at least a first tapered region at the first end to define an opening in fluid communication with the axial passage and adapted at the first end to resist interruption of fluid flow through the axial passage and out of the first end of the blunt cannula. The reservoir is connected to the second end of the blunt cannula.

Boosting catheter and related systems and methods

Disclosed herein is a catheter for positioning through a conventional guiding catheter into the vasculature of a patient, the catheter having a distal tube and a proximal shaft coupled to a proximal portion of the distal tubular member. The distal tube can have a tubular wall, a tube lumen defined within the tube by the tubular wall, a proximal opening sized to allow a medical device to be positioned therethrough, and at least one opening defined within the tubular wall along a length of the distal tube.

A medical device configured to restrict medicament dispersion within a cerebrospinal fluid flow of the patient. The medical device including an implantable catheter having a distal end configured to be positioned within a flow of the cerebrospinal fluid, a proximal end, a body defining a lumen extending lengthwise along the implantable catheter configured to enable a flow of medicament from the proximal end to an infusion port located in proximity to the distal end, and a contoured surface defined by an exterior of the body in proximity to the infusion port configured to inhibit dispersion of the medicament within the cerebrospinal fluid.

Devices and Methods for Delivering Fluid to a Nasal Cavity

A delivery tube and cap are configured to be connected to a container that houses fluid to be delivered to a nasal cavity. The delivery tube includes an inner cannula that is positioned within an outer cannula. Each of the cannulas includes an outlet. The delivery tube and cap are configured to provide relative axial movement between the cannulas. The cannulas are positionable between a first axial position that aligns the outlets to deliver the fluid out of the device in a lateral direction and a second axial position that misaligns the outlets to impede the fluid from being delivered out of the device in the lateral direction.

DRAINAGE DEVICE FOR DRAINING FLUIDS AND/OR WOUND SECRETION FROM THE THROAT AREA, NOSE AREA OR EAR AREA OF A PATIENT, IN PARTICULAR FOR USE AFTER A SURGICAL INTERVENTION IN THE CERVICAL AREA OF THE PATIENT OR IN NEUROLOGY

A method for operating an elastically mounted forming machine which is path-bound or force-dependent, in which method a working stroke of a ram device operatively connected to the drive is initiated by means of a drive, and a predefined forming process is carried out on a workpiece by moving the ram device during said working stroke, in particular due to the interaction of an upper tool located on the ram device with a lower tool located on a tool table, wherein the inertial forces and/or moments of inertia occurring during operation owing to the initiation of the working stroke and/or owing to an imbalance in the drive are at least partially compensated. The method, wherein at least one kinematic variable (s(t),v(t),a(t)) of a rigid body motion of the elastically mounted forming machine is detected during the operation thereof, wherein the time at which the working stroke is initiated is adapted to an instantaneous phase position of the at least one kinematic variable (s(t),v(t),a(t)) of the rigid body motion in order to generate inertial forces and/or moments of inertia so as to counteract the rigid body motion of the forming machine.

Bypass catheter
11738172 · 2023-08-29 ·

An innovative medical device that permits rapid, minimally invasive restoration of blood flow across a vascular blockage. A method employing said device, allowing for lysis or removal of said blockage. Said device creates a temporary bypass using longitudinal structure configured for insertion into the blood vessel and adapted to deliver a side hole to a target area. The side hole defines a distal first segment and a proximal second segment with a lumen to allow blood flow therethrough to the distal end hole. In an alternate embodiment, a slidable outer sheath can cover the side hole to permit reversal of blood flow from the distal end hole to a proximal end hole located outside a patient's body by means of an aspiration controller. Alternate embodiments include an optional anchoring balloon, a macerating stent or wires, perforations for fluid delivery, and a backflow valve.

Urine Collecting System Interventions For Improving Kidney Function

Renal and urine collection system interventions are provided that improve kidney function by manipulating pressures and/or infusing therapeutic agents in the renal pelvis of the kidney or kidneys. Setting a vacuum and/or infusing therapeutic agents in the renal pelvis results in increased glomerular filtration rate, general solute clearance, and free water excretion via the kidney through the urinary tract and is useful for treatment of CHF, ADHF, AKI, CKD, and many other conditions characterized by fluid overload by reducing fluid buildup. The fluid drawn from the renal pelvis or pelvises is delivered to an external or implanted reservoir or to the bladder using flow manipulation mechanism such as one-way valves, occlusion balloons, multi-lumen catheters, and other mechanisms. Pumps are provided for use in establishing the vacuum pressures that are either manual or motorized.

HYDROGEL CO-INJECTION AND REAL-TIME OPTO-ELECTROMAGNETIC MODIFICATION DEVICE FOR TUNABLE IN-VIVO DELIVERY

Described herein are systems, devices and methods that enable dynamic modification of the physicochemical properties of a hydrogel during its in vivo formation and delivery by a catheter. In some example embodiments, an extended endoluminal hydrogel delivery device is employed for delivering a hydrogel within given body cavity, such as within the lumen of a blood vessels. In some example embodiments, a hydrogel precursor, as a non-viscous liquid, is injected through an intravascular catheter and crosslinking of the hydrogel precursor is initiated within a distal region of the catheter. The crosslinking process is controlled, by a control means associated with a distal region of the catheter, to control or modify one or more properties of the hydrogel. The properties may be controlled such that a hydrogel is suitable to embolize the specific target or deliver drugs or other materials beneficial to the site.
