The present invention provides a stretchable material suitable for use in an inflatable medical device. The stretchable material has at least one reinforcing polymer layer with a top and bottom side forming a porous matrix which is imbibed with a sealing material to infiltrate and substantially seal spaces of the porous matrix and extend beyond the reinforcing polymer layer to form a surface coating.

Inserts can be formed with elution characteristics to cause the inserts to elute an antimicrobial agent when subject to a fluid within a medical device. An insert can be formed with a desired geometry to allow the insert to be compression fit within a medical device to prevent the insert from moving or becoming dislodged once inserted into the medical device. The material may also be hygroscopic so that the insert swells when subject to a fluid thereby enhancing the compression fit of the device within the medical device. In some cases, the material can be reinforced using an internal structure. Inserts can be formed in many ways including by casting, thermoforming, or extrusion. In some cases, the inserts can be formed using a peel-away sleeve or material. The peel-away sleeves can be formed of a non-sticky material which facilitates removal of the inserts once the inserts have cured.

The composite electrode type intracardiac defibrillation catheter of the present invention includes a first electrode group including two or more first electrodes for detecting an electrophysiological electrical signal of a site or a cell group in a heart chamber, and a second electrode group including one or more second electrodes located between adjacent two of the first electrodes for causing an electric current by a high-voltage defibrillation electric shock for defibrillation to flow in a contact site in the heart chamber or in contact sites in the heart chamber and in a vein, and a conductive length of a surface of the second electrode in a longitudinal direction of the catheter shaft is longer than the conductive length of the first electrode.

Provided is foley catheter and a composition for producing a foley catheter which is inserted in vivo and a method for producing the same, which the composition consists of the materials which carbon nanotube polymer (CNT Polymer) bonded a carbon nanotube and zinc oxide (ZnO) is combined with a silicon, wherein from 1.0 to 2.2 parts by weight of the said carbon nanotube polymer are combined with 100 parts by weight of silicon.

Medical devices comprise a polymeric body comprising: a base polymeric formulation comprising at least a polymer or co-polymer of propylene; and an additive comprising a copolymer having a polypropylene backbone and hybrid micromolecule side-chains based on organo-functional silanes (PP-g-XSiOA) in the presence of a co-agent, for example, difunctional metallic diacrylate monomers, where X is an organic group or an organo-functional group, and A is a metal, an inorganic oxide, an inorganic hydroxide, or any other inorganic material. X may be derived from a compound selected from the group consisting of epoxy, amino, acrylate, methacryloxy, and vinyl; and A is selected from the group consisting of: silicon, (Si), aluminum (Al), iron (Fe), titanium (Ti), silver (Ag), zinc (Zn), nickel (Ni), calcium (Ca), copper (Cu), tin (Sn); oxides thereof; hydroxides thereof; and mixtures of the foregoing. Optionally, inorganic fillers may be included. The medical devices are laser markable.

A tubing assembly including a signal generating apparatus for a catheter placement system is provided. The tubing assembly includes a catheter and a signal generating apparatus. The catheter includes an elongate shaft having a wall surrounding a lumen. The signal generating apparatus includes at least one electromagnetic coil and at least one electrically conductive polymer that is configured to electrically connect the at least one electromagnetic coil to a monitor unit.

A radiopaque filler material contains a mixture of a first radiopaque material and a second radiopaque material different from the first radiopaque material. The radiopaque filler material may be dispersed in a polymeric material. The polymeric material may be used to prepare a medical device or a part thereof. The polymeric material containing the radiopaque filler material exhibits a level of radiopacity that is substantially even across varying imaging energy levels.
