Therapeutic medical appliance delivery and method of use
First Claim
1. A therapeutic medical appliance for introduction into a cavity in the anatomy of a patient, the medical appliance comprising a tube with distal and proximal ends and the tube defining a cavity extending between the distal and proximal ends, and a first self-sealing membrane disposed in the distal end,wherein the distal end comprises a convex surface arcuately tapered towards a distal tip and defining a distal tip diameter, wherein a medial region between the distal and proximal ends comprises a substantially uniform medial diameter larger than the distal tip diameter, and wherein the proximal end comprises a flared surface with a flare diameter larger than the medial diameter.

Abstract
The present invention, in an exemplary embodiment, provides a therapeutic medical appliance, delivery device and method of use. In particular, plug therapeutic medical appliances are provided that allow for the interventional treatment of pulmonary disorders such as defects characterized by pulmonary blebs and/or diffused destructive parenchymal disease. The plug therapeutic medical appliances themselves combine many of the excellent characteristics of both silicone and metal therapeutic medical appliances while eliminating the undesirable ones. In particular, these therapeutic medical appliances are preferably self-expanding in nature and allow the predetermined differential selection of relative hardness/softness of regions of the therapeutic medical appliance to provide additional patient comfort. An exemplary embodiment also provides a family of delivery devices that facilitate flexibility, durability and/or proper installation of one or more medical appliances in a single procedure. Moreover, the preferred embodiment of the delivery device provides for the reloading of the delivery device with additional medical appliances for additional interventional procedures.

1. A therapeutic medical appliance for introduction into a cavity in the anatomy of a patient, the medical appliance comprising a tube with distal and proximal ends and the tube defining a cavity extending between the distal and proximal ends, and a first self-sealing membrane disposed in the distal end,
wherein the distal end comprises a convex surface arcuately tapered towards a distal tip and defining a distal tip diameter, wherein a medial region between the distal and proximal ends comprises a substantially uniform medial diameter larger than the distal tip diameter, and wherein the proximal end comprises a flared surface with a flare diameter larger than the medial diameter.

23. A method of treating a defect characterized by pulmonary blebs and/or diffused destructive parenchymal disease in a patient, the method comprising the steps of:
-
providing a therapeutic medical appliance comprising;
a tube with distal and proximal ends and the tube defining a void extending between the distal and proximal ends, the medical appliance further comprising a self healing membrane coupled with the distal end thereof, wherein the distal end comprises a tapered, arcuate, convex surface, wherein a medial region between the distal and proximal ends comprises a substantially uniform medial diameter, and wherein the proximal end comprises a flared surface with a flare diameter larger than the medial diameter;placing the therapeutic medical appliance about a target site in a lung of a patient; and introducing an adhesive into the lung through the self sealing membrane; whereby the adhesive causes surfaces of lung sections to coalesce and seal the defect. - View Dependent Claims (24, 25, 26, 27)

28. A kit for treating a defect characterized by pulmonary blebs and/or diffused destructive parenchymal disease in a patient, the kit comprising:
-
at least one therapeutic medical appliance comprising;
a tube with distal and proximal ends and the tube defining a void extending between the distal and proximal ends, the medical appliance further comprising a self healing membrane coupled with the distal end thereof, wherein the distal end comprises a tapered, arcuate, convex surface, wherein a medial region between the distal and proximal ends comprises a substantially uniform medial diameter, and wherein the proximal end comprises a flared surface with a flare diameter larger than the medial diameter; anda delivery device for delivery of the therapeutic medical appliance(s), wherein the delivery device is capable of placement of a plurality of therapeutic medical appliances in a single procedure. - View Dependent Claims (29, 30)

31. A therapeutic medical appliance for introduction into a cavity in the anatomy of a patient, the medical appliance comprising a tube with first and second ends and the tube defining a cavity extending between the first and second ends, the medical appliance further comprising a self-sealing membrane coupled about the first end thereof,
wherein the tube forms a scaffolding, the scaffolding configured to prevent the appliance from undesirably foreshortening or elongating when pressure is exerted along varying points of the longitudinal extension of the appliance, wherein the scaffolding comprises a plurality of circumferential bands connected by one or more connectors, wherein along the longitudinal extension of the appliance, the scaffolding form geometrical interstices, wherein the first end comprises a convex surface arcuately tapered towards a first tip and defining a first tip diameter, wherein a medial region between the first and second ends comprises a substantially uniform medial diameter larger than the first tip diameter, and wherein the second end comprises a flared surface with a flare diameter larger than the medial diameter.
