A needle-injection catheter includes a catheter body having a distal end, a proximal end, a stiff proximal portion, a flexible distal portion, and a delivery lumen extending therethrough. In a first embodiment, a straight injection needle extends coaxially from a distal tip of the flexible portion of the catheter body, and a plurality of penetration limiting elements positioned circumferentially about a base of the straight injection needle and configured to fold radially inwardly against a shaft of the needle when constrained in a tubular lumen and to extend radially outwardly when unconstrained. In a second embodiment, a helical needle extends from the distal tip of the flexible portion of the catheter body. The helical needle has at least one helical delivery lumen connected to receive an injectable substance from the delivery lumen of the catheter body.

Radial and trans-endocardial delivery catheter

A bi-directional steerable catheter adapted for delivery into a patient's vasculature. The pull wires which are used to tension the deflectable segment of the steerable catheter are wound in parallel around the axis of the steerable catheter on opposite sides of the steerable catheter.

Multi-directional steerable catheter

A method for inserting an implant into a cavity in a periosteum region of a patient's palate. The method includes cutting the periosteum region with a sharp surgical tool to create a cavity, inserting a distal end of a sleeve comprising a substantially flat pouch and an implant housed within the substantially flat pouch into the cavity, and pulling a handle extending proximally from the sleeve in a proximal direction while holding a stylet disposed with the handle in a fixed contact with the implant, thus deploying the implant inside the cavity.

A body fluid sampling device is provided. A mesh () may be used to guide blood or fluid to travel directly form the wound to an analyte detecting port on the cartridge (). Thus the volume of blood or body fluid produced at the wound site irregardless of its droplet geometry can be reliable and substantially completely transported to the analyte detecting member () for measurement.

Method and apparatus for an improved sample capture device

A system for inserting an implant into a cavity in a periostrum region of patient's palate including a sheath and a pusher. The sheath has a substantially flat portion, a distal end, and a proximal end. The sheath has a hollow collar on the proximal end, an insertion depth mark near the distal end, and a slit on the distal end. The slit is in fluid communication with the hollow collar. The substantially rigid pusher configured to be disposed within and in slidable engagement with the sheath. The pusher has a distal end and a proximal end. The pusher has a rigid body having an outside diameter for slidably engaging with the hollow collar of the sheath, a tip on the distal end, and a lumen extending from said proximal end to said distal end of the rigid body and configured for fluid communication with a syringe and the sheath.

Cavitation depth, perforation confirmation and implant delivery tool

A body fluid sampling device is provided. A mesh may be used to guide blood or fluid to travel directly from the wound to an analyte detecting port on the cartridge. Thus the volume of blood or body fluid produced at the wound site irregardless of its droplet geometry can be reliable and substantially completely transported to the analyte detecting member for measurement.

A valve for a needleless syringe fitting is disclosed. The valve has a receptacle fitting for releasable attachment to the syringe fitting, a valve chamber, a valve seat adjacent the chamber, and elastomeric sealing bowl within the chamber. The bowl is deformed and partially inverted when the syringe fitting is attached to the receptacle fitting, causing the valve to open. Also disclosed is a valved container in which a vial is sealed by a valve of this type.

A dispenser apparatus for use in dispensing disposable stethoscope diaphragms for removable attachment to a stethoscope head is disclosed. The apparatus operates by removing a diaphragm from a stack, and presenting it for attachment to a stethoscope, when a dispensing plate is shuttled between retracted and extended positions. Also disclosed is a method for reducing the risk of infection by stethoscope use.
