Abstract: A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.

Abstract: A nosepiece for delivering substance to a nasal cavity of a subject, the nosepiece comprising a body part which comprises a base portion which defines a flow passage therethrough, and a projection at a distal end of the base portion which at least in part provides a tip of the nosepiece and confers a rigidity in the sagittal direction, which enables the tip to open fleshy tissue at an upper region of the nasal valve and thereby expand an open area of the nasal valve, and a flexibility in a lateral direction, orthogonal to the sagittal plane, which facilitates insertion of the tip into the nasal valve.

Abstract: A primer may be used with IV catheter systems. The primer may be positioned along the tubing of an extension set such that the primer divides the IV catheter system into a downstream portion and an upstream portion. The primer may vent air from both the upstream and downstream portions to allow blood to flow up to the primer while also allowing priming solution to flow down to the primer. As a result, the catheter may be inserted into the patient's vasculature without first priming the catheter. Once the air has been vented from the upstream and downstream portions of the IV catheter system, the primer may be actuated to open a fluid pathway through the primer. With the fluid pathway opened, the priming solution may commence flowing towards the patient's vasculature thereby flushing the blood from the IV catheter system.

Abstract: An enteral feeding tubing connector comprises a body, a bore extending through the body, and a collet slidably disposed in the bore at a first end of the body. The collet is dimensioned to receive and engage a portion of tubing inserted into the collet, and is configured to resist withdrawal of the tubing from the bore and body upon application of force to the tubing that moves the collet out of the bore. A lock is provided on the first end of the body, and is configured to selectively engage the collet and prevent movement of the collet outward relative to the body. A tubing connection is provided at a second, opposite end of the body, the tubing connection providing fluid communication between another portion of tubing, the bore extending through the body, and the portion of tubing inserted into the collet.

Abstract: An injection system includes a handle assembly with a handle body having an outer surface surrounding a handle body interior and a plunger extending therethrough. A tubular handle collar is telescopically received in the handle body exterior and is axially movable with respect to the handle body. A syringe housing assembly is selectively connectable to the handle assembly and includes a syringe housing and a tubular syringe sleeve telescopically received through a distal end of the syringe housing and axially movable with respect thereto. The syringe housing has an exterior side surface surrounding a syringe housing interior configured to receive at least a portion of a syringe. The syringe sleeve has a proximal end, a distal end with a skin contact surface, and a generally cylindrically-shaped outer surface.

Abstract: A neutral pressure split-septum luer access device is described for receiving a luer lock connector. The septum has a plurality of elastomeric columns projecting laterally within a chamber. Each elastomeric column is under sufficient compression so that the columns are bowed and the column strength is reduced by bowing, but the slit sealing force is high. This configuration places the lower portion of the slit in a tightly sealed configuration which is never-the-less receptive to penetration by the male luer which causes the columns to bow further and collapse precipitously with the elastomeric force of the collapsing mass of the columns being carried distally to displace and pop open the central slit distal the tip of the male luer. The septum further provides a transverse separation between the columns and a distal sealing portion so the force of the displacement force to the sealing portion is reduced.

Abstract: The present disclosure relates to a medicament delivery device comprising at least one microneedle for delivering a medicament to a patient, and a system configured to enhance the penetration of the medicament into skin of the patient.

Abstract: Tissue is resected and extracted from an interior location in a patient's body using a probe or tool which both effects resection and causes vaporization of a liquid or other fluid to propel the resected tissue through an extraction lumen of the resecting device. Resection is achieved using an electrosurgical electrode assembly including a first electrode on a resecting member and a second electrode within a resection probe or tool. Over a first resecting portion, radio frequency current helps resect the tissue and over a second or over transition region, the RF current initiates vaporization of the fluid or other liquid to propel the tissue from the resection device. In one embodiment, an extending element extends from a housing and into a channel in a resecting member as the resecting member moves toward a distal position.

Abstract: A self-retracting syringe has an injection assembly and a retraction assembly. The injection assembly has a housing, a spring rest, and a spring that is restrained initially in compression between the housing and the spring rest. A plunger rod is disposed inside the coil of the spring. A coupler in contact with the spring rest and the plunger rod releasably couples the plunger rod to the spring rest. When a latch is released, the plunger rod moves distally to urge a seal forward, which seal movement causes a hypodermic needle to extend and a medicament to be expelled through the hypodermic needle. A retraction assembly returns the hypodermic needle into the syringe body after the medicament is expelled. Embodiments of retraction assembly provide an inlet through which fluid may be introduced into the syringe through said hypodermic needle. Methods for filling the syringe are also described.

The catheter adapter body may include a compression resistant septum disposed toward the proximal end of the catheter adapter body. The compression resistant septum may have a lumen configured to receive an elongate object. The compression resistant septum may also be coupled to a compression cap that imparts a compression force on the compression resistant septum such that the lumen narrows and seals when the elongate object is removed from the lumen.
