Intended Use

The Boston Scientific disposable IceRod Cryoablation Needle, IceSphere Cryoablation Needle, IceSeed Cryoablation Needle, IcePearl Cryoablation Needle, and IceForce Cryoablation Needle (CX Needles), when used with a Boston Scientific ICEfx Cryoablation System or Visual-ICE Cryoablation System, are designed to destroy tissue by the application of extremely cold temperatures. The Boston Scientific CX Needles, when used with ICEfx Cryoablation System or Visual-ICE Cryoablation System, are indicated for use as a cryosurgical tool in the fields of general surgery, dermatology, neurology (including cryoanalgesia), thoracic surgery (with the exception of cardiac tissue), eNT, gynecology, proctology, and urology. The CX Needles are designed to destroy tissue (including prostate and kidney tissue, liver metastases, tumors, and skin lesions) by the application of extremely cold temperatures. The CX Needles have the following specific indications: - · Urology Ablation of prostate tissue in cases of prostate cancer and Benign Prostate Hyperplasia (BPH) - · Oncology Ablation of cancerous or malignant tissue and benign tumors, and palliative intervention. Dermatology Ablation or freezing of skin cancers and other cutaneous disorders. - · Destruction of warts or lesions, angiomas, sebaceous hyperplasia, basal cell tumors of the eyelid or canthus area, ulcerated basal cell tumors, dermatoffbromas, small hemangiomas, multiple warts, plantar warts, actinic and sebortheic keratosis, cavernous hemangiomas, peri-anal condylomata, and palliation of tumors of the skin - · Gynecology Ablation of malignant neoplasia or benign dysplasia of the female genitalia - · General surgery Palliation of the rectum, anal fissures, pilonidal cysts, and recurrent cancerous lesions, ablation of breast fibroadenomas - · ENT Palliation of tumors of the oral cavity and ablation of leukoplakia of the mouth - · Thoracic surgery (with the exception of cardiac tissue) - Proctology Ablation of benign or malignant growths of the anus or rectum Additionally, when used with the Visual-ICE Cryoablation System, the CX Needles are indicated for use in the field of Oncology for palliation of pain associated with metastatic lesions involving bone in patients who have failed or are not candidates for standard radiation therapy.

Device Story

Disposable 1.5mm cryoablation needles; used with Boston Scientific ICEfx or Visual-ICE systems; CT-guided placement. Needles convert high-pressure gas (Argon for freezing, Helium for thawing) to modulate tissue temperature; internal heating element facilitates active thawing. Used in clinical settings by physicians; provides targeted tissue destruction via extreme cold. Output is visual/thermal effect on tissue; aids in tumor/lesion ablation and pain palliation. Benefits include minimally invasive tissue destruction and symptom management.

Clinical Evidence

No clinical data. Evidence consists of bench testing, including functional testing of electrical heater and cryoablation performance, system compatibility testing with ICEfx/Visual-ICE platforms, and labeling verification.

Technological Characteristics

Sterile, single-use, disposable 1.5mm needles; 90° angled handle configuration. Materials include gas tube, connector, and internal heating element. Operates via Joule-Thomson effect using Argon (freezing) and Helium (thawing). Dimensions: 1.5 CX (175mm length), 1.5 CX S (100mm length). Features low-friction coating and active zone indicator. System-dependent; no standalone software.

Indications for Use

Indicated for patients requiring cryosurgical tissue destruction in general surgery, dermatology, neurology, thoracic surgery (excluding cardiac), ENT, gynecology, proctology, and urology. Specific applications include prostate cancer, BPH, malignant/benign tumors, skin lesions, warts, gynecological dysplasia, and palliative pain relief for bone metastases in patients failing radiation therapy.

Dear Jake Burke:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

# Device Description:

Boston Scientific Corporation's (BSC) IceSeed 1.5 CX 90° Needle and IceSeed 1.5 CX S 90° Needle (IceSeed CX Needles) are sterile, single use, disposable devices used in conjunction with a Boston Scientific cryoablation system for cryoablative destruction of tissue during surgical procedures under CT guidance. The IceSeed CX Needles are disposable 1.5 mm needles that have a sharp cutting tip, a colorcoded handle, a gas tube, and a connector. The IceSeed CX Needles offer a handle configured in a 90° angled configuration to aid positioning of the needle within the CT imaging system gantry. The needles convert high-pressure gas to either a very cold freezing application or to a warm thawing application. Active tissue thawing is may also be achieved by activating the heating element inside IceSeed CX Needles.

The table below provides a summary comparison of the submitted device compared to the predicate devices.
