Abstract: An infusion device including a site and a set for delivery of a substance to a patient. The site can include a cannula that is introduced into a subcutaneous layer of skin of the patient. The set can be coupled to the site by placing the set over the site and moving the set from an unlocked to a locked position. The set can be oriented at multiple rotational orientations with respect to the site, and can be coupled and uncoupled with the site multiple times. Also included is a device for inserting a subcutaneous infusion device into a subcutaneous layer of skin of a patient. Some devices automatically retract a needle used to introduce the cannula. Upon full introduction of the needle and associated cannula of the subcutaneous infusion device into a subcutaneous layer of skin of a patient, the device can move the needle into a retracted state.

Abstract: A site for a subcutaneous infusion device includes a base positionable relative to skin of a patient, and a cannula extending from the base and configured to be introduced into a subcutaneous layer of skin of the patient at a generally ninety-degree angle with respect to the skin using a needle. The cannula includes first and second ends and defines a bore extending from the first end to the second end, the first end being coupled to the base. The cannula includes a tapered wall portion formed between the first and second ends and extending from adjacent to the base towards the second end of the cannula, the tapered wall portion being tapered from a greater wall thickness to a lesser wall thickness as the tapered wall portion extends from the base towards the second end.

Abstract: A needle protector that protects the tip or distal end of a cannula, a trocar, or a cannula/trocar combination, is provided by an extruded tubing that has at least a section thereof that includes one or a plurality of protrusions or protuberances that are configured in a given fashion so that there is a slight bend created at that section of the tube, when the tube is fitted onto a cannula or trocar with the protrusions coming into contact with the outer diameter surface of the cannula or trocar. This results in friction contact between the protrusions and the cannula or trocar to maintain the tube protector in place relative to the cannula or trocar. The protrusions may be punched or lanced in the tube to a given depth towards the interior of the tube to establish a given friction contact.

Abstract: An infusion device including a site and a set for delivery of a substance to a patient. The site can include a cannula that is introduced into a subcutaneous layer of skin of the patient. The site is coupled to the skin of a patient by an adhesive portion including a release feature that allows the patient to remove the adhesive portion from the skin. The set can be coupled to the site by, for example, placing the set over the site and moving the set from an unlocked to a locked position. The substance can then be delivered through the set to the site, and from the site into the patient through the cannula. The set can be oriented at multiple rotational orientations with respect to the site, and can be coupled and uncoupled with the site multiple times.

Abstract: A device for inserting a cannula of a subcutaneous infusion device into a subcutaneous layer of skin of a patient. For example, some devices automatically retract a needle used to introduce the cannula of a subcutaneous infusion device into the subcutaneous layer of skin of a patient. The device can include a housing with an internal cavity, as well as a needle coupled to the housing. The needle can be coupled to a cannula of a subcutaneous infusion device. A member can move the needle. Upon full introduction of the needle and associated cannula of the subcutaneous infusion device into a subcutaneous layer of skin of a patient, the member is automatically actuated to move the needle into the internal cavity of the housing into the retracted state while leaving the cannula of the subcutaneous infusion device in the subcutaneous layer of skin of the patient.

Abstract: A device for inserting a subcutaneous infusion device into skin of a patient. The device can include a housing, a needle hub including a needle, a sleeve, and a spring engaging the needle hub. The device can also include a cap coupled to the housing, and a retention member configured to maintain the device in a ship state prior to decoupling of the cap from the housing. In one example, the retention member can include a boss coupled to the cap and configured to engage the infusion device to maintain the infusion device in the ship state prior to decoupling of the cap from the housing. In another example, the retention member can include a tab formed by the sleeve, the tab engaging a bead on an internal surface of the cap when the sleeve moves relative to the housing while the device is in the ship state.
